I could see the point of a coloured filter for the W30, but at 500 lumens, I wonder how effective it would be with a clear diffuser? Maybe there are better flooders out there for that purpose, but then if you want to carry just one light, and need range for SAR, then some flood for close up, then...….
I remember Eagletac ( Eagtac :ironic: ) used to make a really nice screw in clear diffuser for their M2 and M3 series of lights. I think I have 3 or 4 of them floating around here somewhere. A male thread of about 45 or 50mm dia at a guess. I could measure it if anyone is interested.
Hahahaha, imagine it with a red filter, on top of a hill or tower, and you are dead inline with the beam looking into it, I wonder what sort of distance it would be visible from???? I'd venture a guess of probably 30kms ( 18 miles for imperialists ) or better. Hmmm, sounds like a plan, now, if only I had some hills around the place.
