I have made about 11ty billion threads about this so far, so I'm sorry for making another. Hopefully this will be the last. I ordered a SureFire 6P from CableGuy and wanted to drop in a DealExtreme LED. I have been reading a thread at CPF that talked about each one but it is all pretty foreign to me still.... Anybody who has done this dropin mind telling me what kind they got? I am leaning toward these right now: http://www.dealextreme.com/details.dx/sku.21037 http://www.dealextreme.com/details.dx/sku.11836 The R2 is a lot cheaper but it looks like it would be a lot less bright. I also don't really understand the whole "mode" thing...thanks WMD!
