I'm thinking of buying a Cree XR-E Q5 Emitter on Premium Star which has about 228 lumens @ 1000mA and 3.7 volts. 3.7 volts @ 1000mA is 3.7 watts.
The torch I have is 3 watt, 6 volts @ 500 mA. If I use a volt regulator for step down a 6 volts @ 500mA how many lumens would it give? Would it be 114 lumens @ 500mA and produce only 1.85 watt?
