I use a Streamlight TLR-1 on my real steel.
Tactical Gun Mount Series - TLR-1Žs | Streamlight
ED Rating: Up to 12,000 candela peak beam intensity and up to 300 lumens measured system output |
Remote switches are available as optional accessories
strobing tactical light
But with that said..
Why do you want a light with a strobe function if it's going on an airsoft? Strobe lights are meant more for harm than seeing.
What I posted is probably overkill but it's a pretty good example of how series these things can get.
