This is the Surefire light that came with the filter. The light now has a LED drop in.
Is this a M951 Surefire light?

It will have horrible performance with an LED replacement head. But could be great as a nav light for NODs lol.

This, those filters only work well (comparatively) with the old school incandescent bulbs and heads, because they blocked visible wavelengths but allowed the IR wavelengths to pass through. White LEDs emit little to no IR light.
