Great product

Great light with plenty of lumens, the mount for the pressure pad is easy to attach. Wish the pressure pad was a little smaller.


The cloud defensive mounting solution for the tape switch is more durable than the standard mount. Will definetly add to future rifles


I'd put the Stream light HL-X up against any other weapon light out there. It is super bright, has great throw and is solidly built. The Cloud Defensive pressure switch housing brings this light from a A to an A+. And as a bonus the HL-X is also compatible with all SureFire scout mounts....You can not beat this light for the money


Cloud defense will be the only system that I ever use thank you so much invent thank you so much for Fabricating this quality product....
