Re: FS: Blue Hotlight Kit
Ok, here's some info and pics of my hotlight I mentioned above^^^^
I bought some NJG-18 LED drivers as a curiosity, mainly because of the shortage of flexdrives that has plagued us as of late. I never really used one, and everyone else here were using them on 445 diodes. I wanted to see if they could be used for something smaller, such as a red or a low-power 405. So, I had this hotlight kit laying around. I've seen the methods of coins and such to mount a driver, but I like things clean. So, I planned on making a heatsink extension for the existing hotlight to mount the NJG in contact with the host's positive contact. Here we go....
Stock Hotlight heatsink bored out on tailside
While I was on the lathe, I cleaned up the front-side face with a nice high-speed cut/polish
I turned out this piece to press into the modified hotlight sink. It also has a groove cut into the tail for the NJG-18
2 pieces pressed together
Driver pressed in tail of sink. I set the output at 200 ma with my test load. This setup makes a nice, self-contained drop-in module
Hotlight assembled with a SF-AW210 6X 405 diode.
A somewhat decent beamshot. :eg:
Ok, so I realize that most people that buy this kit do not have a lathe, otherwise they wouldn't buy a kit. I just bought the hotlight kit to see what the fuss was about (it
is a nice host, by the way). I just wanted to share how I mounted a Njg-18 in a hotlight, as well as show that the driver will work on lower power builds. I power the driver with one Li-Ion (4.2vdc). It also surprisingly works well with 3 aaa alkalines (4.5vdc) in the stock battery holder.
I like these hotlight kits. They are simple and easily modifiable. I'm sure alot of people are sad to see them go. Grab the last few while they're available! There were 3 left the last time i checked.
Sorry to Moh for sidetracking the thread with this review/tutorial. :beer:
