This build that I did is hardly warranted but it does show the viability of using the Ecan and an appropriate sink slug to allow for various converters as well as 1 and 5W LED's. I went to the added trouble of modifying and integrating a PM6 reflector since the reflector that came with this particular light was a smooth polished one and I prefer the textured reflectors for beam shaping.
The modified light is the one on the left sporting the nickel plated tab. You can see that the PM6 reflector is deeper and comes in tighter to the LED. Below, and again on the left, is the Ecan module and threaded PM6 reflector compared to the stock issue on the right.
The beams from these lights are too similar to justify beam shots. The mod has a fixed focus and its center hot spot is slightly larger in diameter as well as yielded a lux measure of 1160 over the stock ones reading of 940 lux (both at roughly 1 meter). I used a R2H in the mod so it is likely an unfair advantage. Also unknown is the current going to the stock LED. The constant current going to the mod is 450 mA via a wizard buck/boost converter. Even though the wizard is not a real efficient converter, it requires 350 mA of input current at 5.8 volts whereas the stock unit pulls 516 mA at 5.8 volts. Duh! I guess if the resistor is in series then the stock unit is putting out 516 mA to the LED at 5.8 volts, right? /ubbthreads/images/graemlins/smile.gif
Well no real new ground covered here but it was nice to confirm the functional fit of the Ecan for the TL-2. One can certainly visit this light with other intended photon pumps. /ubbthreads/images/graemlins/grin.gif
If you are an insomniac, you might want to mark this thread as a favorite! I suppose a screen saver showing grass growing would work as well..... /ubbthreads/images/graemlins/grin.gif
