The L3 appears to have more features (like soft switching of modes and more options for them), but is there any output/beam difference between them? They both appear to have the same lumens (per Oveready's site) and appear to have the same optics (just looking at the photos). Other than the bells and whistles changes, is there really much of a difference besides the price? Also, the dropins fit Surefires, but does anyone know if it fits a Malkoff MD2? Since Malkoffs fit SF, I was wondering if it went the other way OR if the L1/2 head will fit an MD3 body or do I have to get a complete light to get a 3 cell setup? Thanks!
