Ironically, four pieces of 5000 mAh Ultrafire cells seem to be able to power a 20000 lumen Ultrafire Skyray King clone, so 12000 lumens should be no problem….
I Just received the Nichia from the last sale. Seems like a great light with good weight too it. All the LEDs are working well. Although I can’t see anymore from looking side on at the light on turbo during the middle of the day. I am using button top 30qs, they went in fairly easy.
Or you can unscrew the tailcap half turn to cut power, then screw on to power again. Light indicates when power is cut off for convenience. Light will turn on in low mode as well. Also not really elegant… but this works as well.
Hello, I have recieved both versions, but in XP-G2 there is a big space between the lens and the besel - it easily accepts envelope end. In Nichia version I was able to insert “only” A4 sheet. Now this makes me wonder 2 things:
1. Is waterproofness really there
2. If I try to screw the besel is there a chance to damage the LEDs?
The TIR lense is seperate from the glass lens, so you should be okay with turning the bezel to tighten or loosen it. Still, it might be best to push down on the glass lens as you turn the bezel to make sure it does not turn and rip the domes off the leds.
Am I wrong? Possible, I am still on newbie level…
…but if so, why? Looks for me that AMC is still within limits with first LED working as a voltage drop.
PS. Forgot the grounding of the first capacitor
Of course I can use Zener diode + resistor on VDD instead of using LED, for better safety but I wanted to show most simplistic design.
