They are both Solarforce... I have both kind... it's just that they varied with dimensions on all their hosts over time... I've seen three different L2M versions so far... the oldest one was the black one from your pic... it has shorter thread area on the tailcap so you can't get a good contact with regular Surefire clickies... however, Solarforce S7 twisty switch they had in offer a year ago upgraded with Oveready McClicky switch works great in that combo... kind of slippery in hands due to Type 2 and glossy finish... I actually use OR Zero-Rez Shorty so I can accommodate 1xAA battery in that host installed in S7 twisty tailcap; the body is not bored for 18mm cells but only 16mm ones...
The cerakoted one you have is newer type L2M but past generation, the new ones you get from Solarforce-Sales are somewhat different... but they feel good in hand and lego with many parts very nicely... pre-bored for 18mm cells, very good P60 host...
Oh, yeah... the older one I bought alone, as body itself on start of my flashoholic career, back in 2010... I believe it was SolarForce dealer based in US... but last two gen's of L2M I got directly from SolarforceSales page and as complete L2M host, with bezel and tailcap (many here know them as: Jo !!! lol)... everytime they answer your inquiry they sign as Jo but you can see that answers sometimes come from different persona, lol...
