Im a little bit confused with the terminology.
Yep. I'll try to explain.
As far as I understand it the dedicated weapon light is like my M952.
Head-adapter-body-tailcap
WeaponLights use terminology a bit different to flashlights.
Lamp Module
Housing
Switch
Note that sometimes the switches are integrated into a dedicated housing for a particular firearm
Lamp Modules are comprised for three main components:
1) Starting from the front we have a "Bezel" (head).
- On your M95 this is the same bezel as is used by the M2 flashlight.
- On the Classic WeaponLight model 628 for the MP5 the bezel is known as the Z32.
2) Next we often find an adapter onto which the bezel screws. This can be a "adapter collar" as is the case for the LU60 as used by your M95, or can be an adapter body (or Lamp Module body) as used by the L60 on the model 628.
3) Lamp Assembly - in the case of the M95 and the model 628 this is the same P60 incandescent Lamp Assembly.
Housings can be split into two main groups:
1) Universal
Universal Housings, such as the MH90 Millennium Universal Housing Body used by your M95, or the A21 Universal Housing Body can either have an integrated mount (such as the M50 Throw-Lever Picatinny Rail Clamp Mount used by your M952 - "2" indicates the M50 mount), or require an external mount such as M79 Universal Clamp Mount for 1" diameter housing bodies such as the A21.
2) Dedicated
Dedicated Housings, such as the H28 used by the model 628 are intended to replace the stock forend of a specific firearm such as the MP5. There are dedicated housings for shotguns, and for carbines such as the AR15 and HK G36.
These dedicated housings have integrated switches. Most common is a tape pressure switch pad. Also common are constant on/off, or system disable rocker switches.
TailCap Switches
Universal Housings [bodies] require TailCap Switches.
In the case of the MH90 as used by the M95, the most common TailCap switches are the XM07 and SW02.
Classic Universal WeaponLights had a huge variety of switch options. When ordered separately they came with their own A21 Universal Housing Body.
So we're hopefully established that a Millennium Universal WeaponLight such as the M952 is made from a Lamp Module, Universal Housing Body with Picatinny Rail Mount, and a TailCap switch.
We've also established that a Classic Dedicated Forend WeaponLight such as a model 628 is made from a Lamp Module, and a Dedicated Forend Housing with integrated switching.
We've also established that a Lamp Module is a WeaponLight component comprising a bezel, Lamp Assembly and some form of adapter collar or body used to attach it to a housing.
Please let me know if I've not been able to explain things sufficiently.
Note that there are many exceptions and variations to this general rule and I don't intend to use this thread to explore these.
