I have the O-likes you are referring to...
The 250mW 650nm is more like 150mW, atleast mine is. It burns but you need to fiddle with the focus a bit to get it right.
The 1W 445nm is a nice laser. The specs are @ 700mW with the waterproof lens. It is definitely brighter with the 3.6 volt 123a's as opposed to the standard 3.0 volt versions.
The 400mW 532nm is a bit of a mode hopper until it warms up, I don't have a LPM, but compared with another 532 I own that has been LPM'd, it's firing at about 300mW...burns well.
O-like is a good company, they ship fast, communicate well. I recommend them.
