There is a heap of variants of P7-lamps at DX but only the "ugly light" (sku.29069) is supposed to be dive-proof.
I have made my own reed-mosfet relay that I have used with success with a broken-off head from this lamp (i tried to unscrew the head but shredded the tube) sku.12060
I urgently needed a light for a dive trip, and simply put the whole thing into another big dive torch, with a strong magnet on a velcro sleeve to switch the lamp. It still works but is really-really ugly.
So,
1. Is there any of the P7 lamps on DX that could be sealed by replacing o-rings at lens, top cap and bottom cap? (I am planning to weld the tail-cap shut and use my reed-relay solution)
The 2 variants I ordered just had a flimsy o-ring either on the outside of the front-lens or behind it "sealing" directly against the threads, which would not work under pressure.
2. About the "ugly light": Does it have a good o-ring seal-solution at the lens? Can the tail-cap be screwed directly to the head? (I'm thinking of a canister conversion of this light)
Cheers
