let's talk about some common mistakes in purchasing flashlight first.

Misunderstanding 1: The higher the brightness, the better

  to improve the brightness in flashlight, the first method is to comprehensively improve the design of batteries and mainboards from lamp holder to reflective bowl. International brands and domestic famous brand products have been carefully designed and tested. Ensure service life and safety. The second method is to remove battery protection board from plus-sized voltage and current: overclocking. Therefore, a flashlight of about 100 yuan was marked as a lumen of 250 or even higher, which resulted in huge calorific value, because the two were not matched, resulting in frequent lamp burning and frequent over-discharge of lithium batteries. Light can only light for a few minutes and often need maintenance, while heavy is caused by high heat!

Myth 3: Orange Peel reflective Bowl may not be better than glossy ones

  the reflective efficiency of orange peel reflective bowl is lower than that of glossy. You can find that the high-power search lights on the market are basically glossy bowls, because the reflective efficiency is high and the range is long. Then why do most tactical flashlight use orange peel reflective bowl? The reason is very simple, in order to get a complete spot. Because the bulbs we usually use have filament, and the spot reflected by reflective Bowl happens to be a projection of filament, and its principle is similar to the phase formation principle of convex lens. In this way, the light spot is a clear filament, which is very ugly. In order to obtain a complete light spot, orange peel reflective bowl is used. Diffuse reflection will disturb the shape of the filament in the light spot, making it more soft. Generally speaking, flashlight of professional players attach great importance to the perfection of light spots, but personally, it is a waste to waste so much energy on light spots for those of us who require practical effects!

The parameter depends more on the actual effect!

The store sells flashlight real marked brightness, long battery life, pure and white light color, perfect spotlight effect! It is an excellent auxiliary tool for engineering and field sports!

  A: bulb operating life 10W hours. In case of bad luck, you can buy it in the electronic market.

  Q: Can I buy another backup battery?

  A: Absolutely OK. The store also sells batteries. But generally, there is no need to buy them, because full power can be used for 2-4 hours.

  Q: What is lithium battery over discharge?

  Answer: the brightness is obviously weakened and continues to be used, resulting in battery damage. Even after professional activation, the power will be significantly reduced. Therefore, please pay attention to the maintenance of the battery at ordinary times, and charge more if you have nothing to do.

High light flashlight maintenance notes

  please be reminded to the torch for day-to-day routine maintenance to enable it to continue to provide you with high-quality of the service.
