I was more hopping to get member first hand experience with them, there opinions as well as what they know on them for I want to add a few to my collection. If there are no "addicts" or experts in this family of Surefires I will just google them. Thanks
Jesse, I would say the responses have been limited so far due to this being in the incandescent section of the forum instead of the LED section. Perhaps you could e-mail a mod to have them move it for you.
The product line looked something like this:
1) L1 - A single cell light with two levels of output controlled by a two-stage switch. Press lightly for low, press all the way for high (momentary mode). Alternatively, the tailcap can be rotated slightly for constant-on low or rotated further for constant-on high. There were several "generations" of these lights with outputs increasing over its life cycle. Some of the later versions were capable of being run on rechargeable LI-Ion batteries for some truly awesome output. The L1 and L2 were different from the remaining L-series lights due to the electronics being packaged in the light body instead of the head. Utilizes TIR lens to focus output.
2) L2 - a two cell light with 2-stage output like the L1. Utilizes reflector instead of TIR lens
3) LX2 Ultra - The latest member of the L family and successor to the L2. Two-celled light with the same 2-stage switching as the L1 and also uses TIR lens. Still in production today.
4) L4 - 2 celled light based on the E2E body with KL4 head. Uses clicky type switch and has a single output level. Uses a reflector instead of TIR. Still in production.
5) L5 - 2 celled light based on the M2 (or C2) body with KL5 head. Was sold with clicky switch and has a single output. Uses a reflector instead of TIR.
6) L6 - 3 celled light based on the M3 CombatLight with KL6 head. Was sold with clicky switch and has a single output. uses a reflector instead of TIR.
7) L7 - Rechargeable light based on the 9AN with KL7 head. Uses a reflector instead of TIR
There was no L3.
The L1/L2/LX2 (along with the A2 and A2L) sort of form a family unto themselves as their bodies are unique. The heads are E-series compatible but their 2-stage tail switches will only fit lights from that group.
The L4/L5/L6/L7 are basically repackaged versions of existing (at the time) incandescent lights, upgraded with an LED head.
