Yellow light to keep night flying insects away.
ALLED is launching a new patent product at market at Mid of May, which is a dual color LED Camping Light, which includes a programmed dimmer switch to adjust the light between yellow and cool white light. And the yellow lighting function is part of our patent content for this light. Some may become confused that what is the function of the yellow light. To explain it, please you may be mentioned of one situation. If you have carefully observated your outdoor security night, you may find that insects and bugs keep circling around and around. You will find the same situation for the road light. So image the situation that if you are on camping trip at night, what is your feeling when you are boring by a set of insects? At that situation, if you have our light at hand, you are sure to be free from that hassel. So you may ask why a light has a yellow light plus will have that effect? To explain that, first you need to understand why insects are attracted to lights? People may have the normal sense that insects and bugs will be attracted to lights. Actually it is not the fact, only night flying insects are attacted by lights. So why?
There is no single scientific explanation for this behavior, however.Some explanation may be reference.
One saying it is that, Nigh flying insects are evolved to navigate by the light of the moon. By keeping the moon's reflected light at a constant angle, the insects can maintain a steady flight path and a straight course. Artificial lights interfere with an insect's ability to detect the moonlight. They appear brighter, and radiate their light in multiple directions. Once an insect flies close enough to a light bulb, it attempts to navigate by way of the artificial light, rather than the moon.
One explanation is that, Light is treated as the sign to seperated Up and Down for night flying insects. As most insets are living in an environment that are surrounding by plants. So for insects, this is normal sense that, it become darker when more closed to the ground. At the opposite, when higher to the sky, it become lights. Besides, for insects, their hunters are more likely to appear on the ground. So for safety consideration, they will fly higher into the sky. At this sense, the light will be the sign of the high position. So it will be one explanation for reason that insects will be attracted by lights.
Actually not all lights will attract insects. Some kind of light radiatioin attracts insects, while some not. Insects are sensitive to a broad spectrum of light ranging from ultraviolet(UV) to red. Color sensitivity in UV spectrum plays an important role in navigation in flying and terrestrial invertebrate animals. Behavioral and electrophysiological experiements found that the insect eye responds to ultraviolet irradiation. This response leads to several different reactions. When insects are exposed to light, they may go toward or keep away from the source of illumination. For example, many insects forage at twilight when blue dominate the irradiance spectrum the sky.
A LED is a semiconductor lighting source. Originally, LEDs were introduced as a practical electronic component in 1962 and early LEDs emitted low-intnesity red light. However, modern version are available across the visible, ultraviolet and infrared wavelenghts, with very high bright light. Based on our knowledge of insect vision and colors across the visible spectrum, it can be assumed that if the LED light emission is towards the higher end of visible spectrum(>550nm), it may be out of the range of vision of most insects. However if the LED light is within the range you can assure that it is visible by insects.

Camping Trip Power Supply

Once you have the opportunities to escape from work, a coupon of weeks, no matter you want to stay in a campsite or explore for a remote area, the essential conditional is you have all necessary gear to be self-sufficient.
This article discuss about the power needs you need for a trip.

When planning a trip, ask yourself some question, “how long of distance I will go?” “ Where will I get a restore?” “How long will I stay there?” All of the consideration will determine the camping gear quantity, the frequency of restore or something else.

Power is the first essential gear you need for exterior survive. Power to your trip is as food to human beings. Your vehicle driving, cooking, keeping food, illumination etc, all of this will need power. So power supply should be given of priority of when planning a trip.
Normally, there are three kind of power supply: battery, gas, solar panel. A combination of these will be recommended as it will give you a flexible power charging solutions.

A dual battery system will not add to your hassle. Choose the right power consumption is also a good way for longer battery usage time.
Fridge and camping illumination are the main factors which draws current. So choose the right kind of these facility is needed. As the fridge, choose a right-size and never leave too many spare space.

As the camping illumination lighting source, change to an efficient power consumption lighting source is a smart choose. Here we want to do a calculation for you.

When a car battery is fully charged, for example a 12 Volt 55 AH Deep Cycle AGM Battery, the capacity of the battery is 12V X 55Ah=660Wh. To use the same capacity of battery, different lighting source really make a great different. A 10W Halogen G4 for example, your battery can provides a 66hs continuous illumination for one of this light.  To reach the same brightness level, a LED G4 bulb, it just charges 2W of power. That means it provides 330Hours continuous illumination for the same capacity of a car battery.

Lighting source	Halogen G4	LED G4
Wattage	10W	2W
Brightness	150Lumens	140Lumens
Car battery	12V 55AH	12V 55AH
battery continuous illumination hours	66	330

Gas is another power solution especially when conducting cooking. But storage safety should be aware of. Storage of LPG can also be an issue, as it needs to be carried in certified tanks, which means to carry enough gas to power your camp lights, fridge and stove for two weeks can prove difficult.

Solar panel is a complementary power solution as on your trip you are hardly short of sunshine. But you need certain investment on the equipment for it. A 240W system will easily run a 60L fridge, all camp lights, charge all batteries for phone, camera and perhaps a laptop with only 5-6 hours of sunshine a day.

LED Camping Light Installation Spare Accessories Usage Guide

How to fix a LED Dual Camping Light
Actually when going outdoor to conduct a camping activities, it is hard to find a solution to fix your light. A lantern for example, you can place it directly on the floor or hood it at the top. A UFP kind LED Camping Light for example, it is designed with the magnet design, which you can have seperated parts attach to each. But actually it is hard to find a light with the perfect fixing or installation solution that fixs exactly for the tent/ awning area.
ALLED's LED Camping Light has the advantage over the similar product at market. Because it has really considered the tent/ awning environment. It is designed with a transparent velcro coat, inside which a flexible strip light provides illumination. Actually it is the velcro strape coat that makes its difference at fixing aspect.
Turn to the back of the light,you can see this spare accessories, you can tear them down to have a look. From left to right, you have three pieces of velcro strape, a hooks with velcro strape, a veclro back. When got this light at hand, not every person have the clear idea of how to use this accessories. Here is the brief introduction of this fixing spare accessories usage.
The tent or awning will always included the bracket support structure. But perhaps not every one with this LED Camping Light at hand know how to take advantage of this bracket support structure and our velcro strape accessoies to fix this light. Image above is the demonstration of the usage of those three veclro strape. First tie them down from the light body. Then find a bracket area to round the velcro strape. You should go a few distance to paste every velcro strape. As this light is 1200MM in length, every 400MM to paste a velcro strape is recommend. Of course, you do not have to use out three in total. In some situations, only two pieces of this velcro strape can hold the weight of the light. After you fix the velcro strape, then attach the back of the light to the veclro strape. This installation is the "patent" idea, at the market, you hardly find any similar product. As it is so smart that, why not have a try yourself.
Secondly, you can see the hooks with velcro strape.
Nearly every one notice to use the hooks, but not every one knows the details.
The hooks at ends of this LED Camping Light is another fixing solution to take advantage of the tents or awning braket support struction. So how can you settle a distance if the 1200MM is not enough from one end to another end? Here is why this hooks is designed with a velcro strape. But few people notice that this hooks it is with a velcro strape that can be tie down from the body of the light. When you need to settle a distance, you can tear down the veclro back which is along with the hooks, so that it longers. But the velro back which is tearable is just about 250MM long, if it is still not enough after that, you need to settle it yourseleves.
If you can find a smarter usage method of this LED Camping Light, please enclosed a image to show us. If your solution can be an inspiration, you will get a gift from ALLED.

LED Camping Light Dual Colour Restore Method

LED Camping Light Restore Instruction
When you get a LED Camping Light at hand, you will receive a portable package bag from us. Open the zipper of the bag, you will see the light accompanied with all of the accessories( cable and cigarette connectors) lying tidily inside. This light is with a 10M cable, so its cable is rounded by a Velcro back, putted in central of the strip light.
The package bag is not for one time usage. For your recycle usage of the package bag, you need to know how to put back the light onto the bag. But after usage, you may find all things in disorder situation. When restoring the LED Camping Light onto the package bag again, you may come across with the difficulties as followed. 1, The cable is so long that, it is hard to get it in order again. 2, It seems too hard to put the light back onto the package as the restored one is in larger volume than the package bag.
After usage, hard to restore again?
Here is the step by step restoring instruction of this LED Camping Light.
Firstly bundle up the cable. Taking reference of the crease created before will help to take a right dimension.
Secondly, use the Velcro back to tie the cable into bundles.
Thirdly, Round the LED Strip Light. Which radian to take when doing that? Excessively limited radian when rounding the strip light will damage the strip light inside the transparent veclor coat, as there is circuit board inside. But too wide radian is not proper too, because its volume will become so big that you can not put it inside the bag. So take a proper radian when rounding the strip light is needed. Off course you can do adjust at the final step.
Fourthly, put the rounded strip light into the package bag. Adjustment may need to attach the enough space.
Fifth, put the cable bundles at the middle of the strip light.
Sixthly, close the bag with the zipper. Then you can see put the camping light tidily on to your camping equipment. ?

Explore 4 wd driving skills

Explore 4wd driving skills
As you know,it is important for a 4wd driver to be a good hand at Mastering the driving skills.Actually, as far as its geographical features are concerned,it is a magic land with many certain regional elements ,including highland and lowland, deserts, plains, gobi, swamps, lakes, rivers, streams, wetlands, coastal and tidal flats.Therefore, to thread through complex Australian continent at ease, I am afriad that your positive picking up a good driving skills for off-road is inevitable even you are always under the illumation of good quality 4wd driving lights.
Basic structure understanding
First of all, every driver should be familiar with their own 4x4 off-road vehicle, fully understand the structural features of automobile parts,such as tires, transfer, transmission, steering, suspension, clearance from the ground, the brake,whose functional characteristics should be worth of your Primary focus. And whether you make a driving off-road vehicle could have great something to do with some relative abilities,like controling the speed for engine and driving, mastering the time to shift and into the bending Angle. Undoubtedly,handling the skills tends to not only help you out of the obstacles quickly but also lead you to enjoy the pleasure of cross-country challenges in complex terrain.
As you know, there are differences in the nature of 4wd and the ordinary vehicle, which is the pattern of displacement mode, the former has 2 and 4 displacement mode while the latter only owns the displacement mode of 2.
Generally, the 2 displacement mode is operated in dry highway, ordinary highway. While the 4 displacement mode get accostomed to be used in either rain snow weather or wet roads,because both front and rear wheels of the latter, as the power output wheels,are able to prevent the sideslip phenomenon resulting from uneven distribution of kinetic energy,which guarantees the stablility and safty in high speed driving.
Driving recipe for 4wd
Here we will take the topic to off-road driving skills in several typical terrain conditions.
1. Rugged track: the gobi desert, gravel, stones, dry river beds, mountainous area
Driving through such natural wide terrian, all you have to do first is to ensure the  minimum distance from the vehicle to the ground.And slow down to avoid the collision of chassis and stone when you 4wd is threading through the stones or dry wash.Generally, Setting the transfer case with 4 L gearbox, 4wd can run over rocks 20 cm below. The stones unable to run over,get out of the 4wd and shed it in hand ,but if the stone is so big that small stones can be made best use by placing in front of the big one to Combine a temporary step. And you need to make sure that other end of the big stone is placed stones as well, otherwise, the front chassis will met rocks.
2. Steep slope :in mountain, DAMS
In climbing the steep slope,for the common 4x4 ,the limitation in climbing angle is from 30 to 35 degrees or so, which is influenced by many internal or external factors ,including body design, gear of transfer case, tire grip, degree of dry and wet,degree of slippery. Generally speaking, long wheelbase is better than short one with 4 L hanging up before entering slope. Then,star the gearbox with the first gear, then go into second gear, keep the vehicle constant speed with a certain throttle, in order to avoid the wheels skid. To be honest, the primary requirement for a qulifiled 4x4 driver in the incline, would turn out to be not slipping and not shutting down. On your way to the slopes , your had better must meet slopes, not in lateral riding. once the side slope is more than 30 degrees, the vehicle may occur side tumbling, only to bring out extremely serious consequences. If the 4wd is too underpowered to go forward halfway, immediately can you stop to hang the reverse, by means of using the engine of pulling resistance, cooperating snub, keep the steering wheel straight, you would be capable of slowly backing to the slope.
	In the narrow mountain path,it is the most important to correctly grasp the steering wheel. Downhill dosn’t take much horsepower like the uphill, but it is also a danger under improper operation.Actually, it is a common sense that drivers can't continue to hit the brakes. In steep slope with transfer case 4 L is a good way to control the speed.When meeting the corner,you  should slow down ahead of time to avoid air brakes, which is supplemented by gearbox low gear to control speed.And of course,just make slow brakes if necessary.
	In the mud, transfer case 4h, gearbox with second or third degree and fixed throttle can cooperate to make you succeed in passing. Need to remind you whenever you encountered a glade with marsh mud more than one feet, be careful and once vehicles carelessly enter, the vehicle is slowly sinking no matter how great trouble you cost in trassimision, only looking for help and drag the poor 4wd off quickly. In the mud road of hard bottum, go forward with transfer case 4 h or 4 l. Although you grip the steering wheel, the body is still slightly move like snake,which doesn’t matter as long as the vehicle dosn't deviate from the lane.All you need is to have a psychological preparation. When coming across wheels sinking slightly in mud with the soft foundation, you can have transfer case with L4, gearbox with a second gear and steer wheel slowly in order to go forward.
In soft-mud advance, ground subsidence aside, make body tilt and unable to quickly pass. You can sort it out by several steps:after reversing, place stone, wood and other hard objects in road ditch, and then advance with transfer case L4 and fixed throttle.Unless the distacce of the mud road is short, it is necsssary to keep a certain velocity potential.in the journey, if there is a small hard things in your way, just run over directly. Slope mud frequently make vehicle skid, and you can improve sectional situation by adding anti-skid chains.And what you can’t miss to help reducing tire air pressure is strong grip tires.
3, sand: desert, flowing sand, dunes and beach.
The feeling of catching the wind in fast 4 x4 in broad beaches, only happen on you when you are indeed in that occasion.
If 4wd is steering in sand and its tire has a little bit down in the sand, which is slightly. Usually 4wd can be unimpeded in the flat sand, by setting 4h transfer case gearbox second or three gears.
After the current wheel reach to the sand dunes, the rise of head stock will make the center of gravity fall onto the rear wheel, both sides of rear wheel should be touch the ground with the same weight at this time and the body does not tilt. Otherwise, whether it is a transfer case H4 or L4, all elements above can result to back idler wheels sandblast phenomenon.
If continue to trample accelerator in such situation, only turn out to be still round back idlering, may also be got in deeper and deeper. Now it is time to use the winch or calling for a car to help. if you are kind of person to prefer overcoming things in person, just get deeper digging to two wheels under the sand, and place the wood, stones and other hard objects on the wheels. And with transfer case L4 and transmission gear, you ensure the friction of the wheel rotates make hard objects forward . According to the theory, it is not commen for 4 x4 to be stuck in sand, but there is a special case, when 4x4 drives into the sand in two wheel drive,  not shift with continuous forward might not have your 4wd be stuck in the sand.Once starup again after parking and use two wheel drive, fierce at two times, which is expected to more than half of the two transmissing wheels sinking in the sand. At this point, of course, the last resort would be the transfer case for L4, and if the situation of sinking in the sand is not deep, there is indeed a opportunity to climb up.Otherwise, even the other two will also turn in the deep.
If it is three wheels that are trapped in the sand with depth ,which is deeper than the wheel diameter by more than 40%, now the opportunity of climbing out of the sand counting on vehicle dynamic is almost zero. At this point, the friction forward of wheels under the pad hard objects, might as well be a solution to get rid of hardship,or you can get outside for help.
4, wade: shallow rivers, streams, reservoirs, lakes, cities dips water area, are all the terrain the 4x4 would encounter.
As the setting position of the electric system, air intake and exhaust system are higher, 4wd has better ability of wading,the general 4x4 wading capacity has something to do with the tire height. Wading before driving needs probing depth, but it is no easy to master the uneven bottom of the riverbed.The water depth difference between the head street and the tail street sometimes is great. And please pay attention to control the speed, it is frequent situation that splashing wet circuit and bring out shutting down.
	When the depth of the water may flood the exhaust pipe of the terrain,setting the transfer case with L4,making gearbox with a second gear or one gear, holding the throttle to keep the engine high speed and avoiding the shift in water,are all the ways to make the exhaust pressure greater than the water pressure in case of inflowing water,And the wading depth is up to be 20 cm higher than exhaust pipe mouth. In the jet stream, Vehicles have to prevent jet impact.Crossing the river in 45 degrees of the current direction is a rather safe way. Undoubtedly, some drivers with fewer Wading experience would be afriad of flameout in the water, once flameout happens in the deep water, you should immediately shut down all car circuit and not attempt to start the car.Otherwise, the simple behaviour would lead to significant damage due to water drawing into cylinde.It is best to research for other vehicles to pull out this 4wd.

Conclusion

As conlusion,successful off-road driving skills should be a perfect combination of wisdom and courage. Only relying on more practices, repeated experience and frequent summarizing, you,as a 4wd driver, can gradually improve the level of off-road driving.

The yellow color of the LED dual color camping kit

The yellow color of the LED dual color camping kit

When you indulge yourself in the cool gentle wind or board vision in the camping trip, have the bug or month ever be the blue invited ,haunting you with constantly “singing”. Nonsense with screaming or complaining, here you can guarantee your tranquility by means of a special color lighting of LED dual color camping kit, which is competent for keeping the invaders away obediently instead of shedding their blood.

Principle for driving insects

Wonder why the lighting of such extraordinary could fight against the enthusiastic insects, the problem will be figured out in the spectrum.

As the secret is a kind of yellow color, with light band in dominant wavelength 580-650 nm which the moth has to dislike naturally. Under such yellow color lighting surrounded, you can keep from nocturnal insects ‘disturbing like the boring moth or mosquito. And the led dual color light is adjustable lighting with gentle illumination, which is comfortable for eye glaring. By the way, please avoid the mix application with fluorescent tube or other light bulb, in case that various waves interfere with each other and lose effect. Unless you miss the camp with moth and mosquito’s circuiting around.

The yellow lighting is gentle for glaring,isn't it?

dual color camping kit vs tradition moth repellent lamp

May someone would think of the traditional trap lamp for the issue. So, why not makes a arena possible for the LED dual color camping kit and the trap lamp.

1. working principle

While the traditional trap lamp is designed by using the nature instinct of insects’ phototaxis, and mosquitoes would drawn to lamp lights and get deadly electric shock by touching high-voltage-power grid around the outer tube. And it makes use of long wave ultraviolet (UVA) lure source, and its lamp wavelength and UV lighting quantity emitted by the trap lamp will influence the mothproof effect. Mosquitoes, also includes a lot of moths, flies, spiders, etc will all to be the victim will not escape, while the LED one just keep them away by means of the mothproof color ,not to shedding their blood, which is more environmental and there is no need to cleaning.

The trap lamp

2.Impacts on the human health

The impact on the human health should be another focus. As the UV energy of the trap lamp would have something to do with the biology changes. If the skin exposure to the UV for a long time, and the long wave ultraviolet light can deep into the skin.Therefore , the UV gets used to be regarded as one of the factors that cause skin aging and skin cancer. And if the skin exposes to UV for a long time, the eyes would also suffer from lesions such as cataracts and other diseases. Fortunately, the UV containment level of the LED dual color camping kit is low enough to guarantee your relief in the health.

Even though there is criticism about the led’s lighting, whether the light is sufficient good enough for the health, as the Blue-ray just can reach the eye through the pupil, lens and vitreous body retina, which does harm to a degree. But you know it is just for the led lighting with abundant blue , while the color with ordinary blue color , green or the yellow we are talking about, are all safe light sources that will not cause any harm to human body health.

Conclusion

As you can see the comparison of the lighting principle and lighting influence on health, LED dual color camping kitis environmental, appropriate radiation, comfortable for the eye’s glaring, taking a overwhelming superiority in the lighting color. Remember choosing a qualified and environmental camping kit, LED dual color camping kit with yellow color!!

Flexible LED Camping Light with Yellow Light function and velcro back design

It is with Yellow light to keep night flying insects away.
