If you want them to last and make it through a couple night hunts when the sh1t hits the fan, spend the money on a good light. If you are easy on your stuff, buy direct from China for about $25.

I spent money, $130, on a "good" light and the good lasted until a lens fell off and scattered the hogs when it hit the floor of the stand as I was raising the gun to shoot.

On the other hand, I have bought six cheap Ultrafires for about $12 each, the 501 and 502 series, in white, green and red LED's, I take them hunting with me every other week, and they have not given me any problems. I'll even mount them on my rifle when hunting at night. I keep the batteries charged and they work.

So much for the theory of you get what you pay for.

I have found that lights are like anything else... You get what you pay for. Careful buying the cheap china lights that have no warranty. I have heard a TON of stories of guys getting a great deal on a light only for it to crap out the 2nd or 3rd time out. Save yourself the wait and Heartache and buy a light with a warranty. Something like Wicked Lights, Coyote Lights, somebody who has been around a while. Good Luck.

I find it hard to believe any light being more worth the money than a UniqueFire T20. Put a doubler on it for $15 and you can get a "high pass" filter in any wavelength you want for $15. Why spend 3 times as much than need be?

Here is what I would buy
$19.99
UniqueFire T20

$29.98
Panasonic ncr18650b w/charger

$3.28
Lens adapter that fits UniqueFire T20. Must be pressed on.

$11.29
2x lens with 52mm threading

$11.95
720nm cut filter

So that's $76.49 including batteries and Charger. These lights are crazy bright. If your going to mount it on a weapon you will want to wrap Teflon tape on the focusing thread to create a snug fit.

Watch this video. These are 940nm T20's. Which means they can not be seen by humans. Thanks to Hard_ware, he shared this easy and inexpensive mod to increase the lights range by about 25%. The parts are a camera adapter that adapts from a Panasonic LX3 lens to a 52mm filter thread, and a 52mm thread 2X telephoto lens.



The camera adapter fits tightly over the bezel of the T20. The press fit requires the use of a vise or a clamp. Here the adapter was started by hand then transfer to a smooth jaw vise to squeeze it further down the bezel. Warning, you should remove the T20 bezel from the host before placing in a vise or clamp.



Shown here are a stock light, then a light with the adapter attached and lastly with the 2x telephoto lens mounted.



Here is a video of before and after using a 940nm pill in the T20 host. Camera Zoom is out all the way so the whole beam can be seen. I zoomed the lens about half way through the video. The first light is without the doubler. http://s1284.photobucket.com/user/edgeer1/media/T20_2x_mod_zpsfc9e5e38.mp4.html

You can try our lights, I've got several to choose from and a 3 year warranty, anything happens being it to me and I'll replace it!
