So after a few hours of search CPF and Google I surmise that battery life is calculated as such:
Battery Life= Battery Capacity in mAh/(Lamp Wattage/Battery Voltage (Total of all Batteries)=Discharge Rate in Amps)
So in my case, I bought a LED replacement bulb for my Surefire G2Z with a Cree XLamp XP-G which is rated at 4.9W and assuming 2 123's @ 3V each giving me a total of 6V @ 1600 mAh.
That would give me:
Battery Life= 1600mAh/(4.9W/6V=.816A or 816mA)=1.96 hours or 1 hour 57 minutes
My understanding of lumens is this:
Lumens=Bulb Wattage*(Lumens/Watt)
In the case of the bulb I ordered it is 4.9W @ 93lm/W
So I would have 4.9*93= 455.7lm
Do I have this right? If so great, if not some input would be great :thumbsup:
