i just got a m1 led to night and put a t-bin 3 watt in. so i did a run time test with a powerizer 3.0 volt rechargeable. it ran 1 hour and 10 mins at full out out. i am happy with the run time off one cell.but the werid thing is the i have the a m3 3 cell with the same t-bin with the same code and it ran for 1 hour and 10 mins with the same three cells. same out put from the two lights but one eats up run time. i could just use the m1 for 3 hours off the same 3 cells. what is the deal with this. because i may take back the m3 for that reason, is this a freak thing or what.
