I just received a XP-E 20mm alu version of this zoomie. Shelf is semi-hollow, with ~7mm dia opening right in the center. Strangely, I almost kill my emitter even at 1.9~2A.
Finishing is average like Ultrafire F13. Light is not really usable in stock form imo.
It looks like Klarus has updated their RS20 so that the side now uses XM-L color led. (But most vendor sites that that I looked at just now still list the previous RS20 with the ‘switchable’ led). http://www.klaruslight.com/plist_show.php?id=142&lge=en
Thanks, I also saw a post in another thread where the XML was cranked up past 2 amps. 2 amps looks like the point before diminishing returns assuming good heat sinking. Maybe…
I am looking for the RA-601ZOOM 5 mode CREE XM-L RGBW 4 color in 1 LED( red blue green white ) Police torch Tactical Flashlight in the U.S… Not the EagleTac D25LC2.
in 2019 are there any torches/flashlights with really bright rgb(w) leds like cree xm-l? i am struggling to find any. really i want a mini party light. thinking of making my own and having it usb powered
I'm very much interested into the Lumileds SST-90-R that can be driven to more than 13A. But these are probably difficult to put into a flashlight and require special centering rings and reflector apertures.
I’ve looked and looked to for a few years now - nothing. I even bought the multi led and driver and built my own in a host, sadly it lasted a week or so and the red part/emitter/quarter died.
Still after one though, if you find one please drop a link in here!
Here is tab dump of my current diy research. I am not going to try and make it fit in a torch housing. thinking of reusing motor bike led light housing. i want it to be a flood patten. so i dont need lens, just heat dump and protection.
To drive it, a bunch of little driver modules, else some resistors. 5v usb supply.
to control, a little rgbw led strip control module. there cheap and easy to get. some of the really cheap simple ones can be driven from 5v i think. they are not good for video as the pwm stripping shows up in any video of the light output.
