StreamLIght Jr. Luxeon \"Turbo\"
I got a SL Jr. delivered today and had it on the *table* in no time. /ubbthreads/images/graemlins/icon15.gif
I had to remove material from the bright Al retaining nut as well as the 27 mm reflector to get the reflector down into focal range. Although the LD is not a bad beam with the reflector, this was to be a turbo so I took out the LD star and replaced it with a R2K star that I had. I chopped the rear end off a PR head that I had and bored and tapped it to go on the Jr.'s body. I couldn't cut the proper pitch (34 TPI or perhaps metric) but a 32 pitch worked because I ended up with very little thread engagement anyway. I was surprised to see that a cut down star was used instead of an emitter. While the LED was disconnected, I did a quick bench test and if I recall correctly, there was 320 mA at around 2 volts going to the LED and maybe 440 mA at 3.3 volts or so? Anyway, I suspect this is not a constant current driver but I leave that to the electronic experts.
At one meter, the stock light mesured 340 lux and the "turbo" measured 1230. This is kind of a cool light and longer than I am used to. Below it is compared to some other "long" lights:
Although the subject line includes the term turbo, it's probably a cheap shot including the pedestrian E3t with its 11400 lux, 120 lumen "scalped" P91 but in grabbing the "long" lights, I culdn't resist. /ubbthreads/images/graemlins/nana.gif
