Uniquefire UF-DT1 is now only $16.39 at DD. With coupon code 10OFFSALE it comes down to $14.75!! It is supposedly well built and water proof with magnetic tail switch => I pulled the trigger to see how it performs..
This is supposed to be the new version with XM-L emitter, but the price is good even for XR-E. (The specs are a bit messed up, so it might be either XR-E warm white or XM-L T6, a bit gambling..)
I don’t see “diving” in specifications.
Yes. It's meant for diving, even though the outer spring in the magnetic switch is not stainless (or at least wasn't in earlier versions).
Looks like a xm-l from the pics, but 200 lumens and when you read the description further down its a 1000? Standard chinese xm-l claim…
7500ma too, better use an IMR then… 
I'm 90% sure it's XM-L. Let's see in 2-3 weeks. :)
DIving light with clickie switch
Peculiar (at least for me)…
If its somewhat water resistant, its nice deal though.
Where did you see info about its diving abilities?
Are there some reviews, forum comments etc? PLs give us link if you can find one.
Clickie moves a magnet, which triggers electronics inside the tail cap. Fully water proof.
As I said earlier, the only problem is (or at least was) that the spring inside the clickie was not corrosion proof. (but that can be easily changed, I hope…)
Aha, here are some user comments http://www.manafont.com/product_info.php/uniquefire-diver-light-ufdt1-q5-150lumen-warm-white-led-flashlight-silver-118650-p-7274
In fact Im off oppinion that manafont forgot to delete “diver/diving” from this page.
I’ve noticed that some lights are elsewhere (ebay etc) advertised as diving lights, and manafont doesnt mention diving on pages of these same lights. Probably being afraid od returns etc. Honest approach…
HEre’s some talk about it on cpf - but nobody really tested it at, say, 40 meters
