Re: MDs Lithium-Ion>Incandecent guide, +compatability/comparison chart
It (the G140 with 4 x RCRs) is noticeably whiter and brighter than a G120 with 4 x primary cells. I'm not sure that I would describe it as "blazing" but certainly it's a worthwhile improvement. It doesn't appear to be on the verge of self destruction and it works fresh off charger. As an aside I just saw that QCG lists the 502D (4 cell) Ultrafire as suitable for rechargeables. I presume that this is the G140 lamp assembly so the factory must have developed it with RCRs in mind. The G120 is no longer listed as a separate item which is a shame because it was a much better bulb for primary cells.
