out of the box, the flashlight has the lens and reflector glued on, do not worry if it is hard to unscrew, you will NOT break it

grab the flashlight and twist counterclockwise
do the same with the led module(by the way, if your flashlight ever starts to get dim and flicker, clean the aluminum where the led module connects to the flashlight, aluminum against aluminum oxidizes badly and the connection grows poor)

wow, i do not like the rebel line of leds
my 3rd flashlight(yay for menards replacing it free when it dies) 1st 1 went blue, 2nd 1 flat out died, 3rd 1 is now blue again(with no intentional damage what-so-ever to any of them) rebel diodes are small and bright and built hella cheaply

bad news all the blue led flashlight is no more, i accidently dropped it on the end with the cap off and it stopped working... oh well, i got a new white rayovac, gotta love menards return policy, they gave me a new 1 no questions asked

Nice idea, especially with scraping the phosphor off the rebel. Blue light is just cool. I wouldn't try this with anything but a TFFC rebel or K2. With anything else you'll probably rip off the tiny bond wires with the scraping and dome removal.

What is the advantage of a blue flashlight over a white? (Forgive my ignorance ...)
Conventionally a red LeD is used in dark environments, to not disintegrate you natural night vision. An incandescent or white light causes your retinas to close making it hard to see, in the darkness around you. I would imagine blue would work in a similar fashion. Not sure if that is the purpose of this particular I'ble. It may be of advantage because it is just nice looking and unique though.
A blue LED is at the 430-460 nm range. Night vision is based on IR that is in the 900 nm range. Red is about 560 nm. The advantage is that the blue is less detectable by night vision. Check this light out and the research http://www.phantomlights.com/faq.phtml
Thanks for the clarification. Although I do doubt that being "less detectable by night vision" was the main purpose of this particular convertion. Not exactly alot of people using night vision to track you in the burbs.

added a pic of it in comparison to other light types through nightvision

i own a gen 1 tube based night vision scope, your understanding is very off, night vision scopes gather ANY light they can, from uv to fir, they amplify it and send it into a phosfer screen thus making it green

If that is true I would like to see a photograph of the research that you have done to prove your point. All of the research that I have done with my gen 1-3 tubes have shown a significant reduction in dispersed light. It is true that all night vision works across the spectrum, however, it is designed to be more sensitive toward the IR end. To tell a person their understanding is " very off " is quite rude. So lets see what you have now: pics, research, or just uninformed rudeness.

eh i'll take pics through my scope some time, maybe its just that this flashlight is bright as **** but its MUCH brighter than my ir emiter

Have you even looked at the link that I posted?
Yes, very interesting.
Thanks to both.
