Botach shows SureFire LED conversions for the Executive lights and the 6P on their website.
The KL1, KL2 and KL3 have been released a while back.
Having all three, I don't think any of then are suitable in terms of beam throw to be WeaponLights.
For example, the KL2 on the M111D I have just does not justify the size and weight of the M111D - these Series of WeaponLights are best used with the MN11 High Output Lamp Assembly in my opinion.
I find the best LED "Luxeon" Conversion Bezel is the KL1 on either the E1e or E2e.
