For $5 at a gun show, who could resist?
I bought an SE 8 led fl308bu blue anodized cheapo light. Normally I wouln't give ona a second look, but a budy went with me, and picked up the one they had laying there to look at and blinded me with it.
I got mine home and put 3 fresh AAA batteries in it, and while it isn't a surefire, by any stretch of the imagination it is a bright little sucker.
After testing it thorougly, I did what anyone who is pleased with their new purchase does. . . I took it apart. (whadday mean you don't do that?)
It has a simple, but suprisingly well machined aluminum body threaded at both ends. In the but cap is a simple click on/off button with a rubber cover.
On the buisness end it has 8 leds aranged in a ring aound the outer edge of the lense and the "reflector" (chrome plastic) is pretty much flat and IMHO for show only. There is a threaded metal washer that holds the guts in the head. It is easily removed with a large allen wrench or a small screwdriver if you are careful not to goober up the threads.
The led's are all wired up in parallel, no resistor, no current limiter of any kind.
I guess they are not figureing on anyone using anything other than plain old alkaline batteries in it, as they have a tendency to drop current under load more so than lithium or even nimh rechargeables. Those would probably make it even brighter, but I doubt it would survive long.
All in all I have to say it is a cheap, semi disposable light that seems to work well. I am in the process of trying to get a few to hand out at Christmas this year.
