Jetbeam RRT21 for diving 15m+ underwater

[airmj]

Hey guys, I've been looking for a light to take underwater for my diving expeditions. Existing lights made for diving are either too dim, too expensive, too big and do not have the right beam profile for my uses.

Tried using a Jetbeam PC25, brought it down to 15m depth, but the tailcap and side switch got depressed all the way because of the pressure. So it got permanently stuck on strobe mode. I know 15m is way beyond the specified 2m depth, but damn these lights are so compact and bright, it blows all other diving lights out of the water.

I'm thinking of testing the RRT21 / RRT15, because i can control it using the magnetic ring, and even if the tailcap is depressed, i can twist the ring to turn it on, off, strobe and adjust brightness. I'm confident that the o rings sealing can withstand the pressure, Im just not sure how the magnetic rings are built and their sealant method.

Anyone have experience with the RRT21 or RRT15?

Thanks!

Define too expensive?
I would imagine that if you keep testing several lights you could have purchased one diving light at close to the price of several test models.

Buy once, cry once.

I'd say buy a diving light. Most lights are rated water proof until 1 meter, they are not designed for diving.

Honestly I do not know any diving lights, only the Led Lenser D14 and the Polarion Abyss.
