Good Back Up Light under $50

[redacted]

so even though the switch was crap. I took it diving. Failed and leaked at 65 ft depth upon first submergence..why do i beleive stuff I read on this board?

Did you upgrade the o-ring first?

Nope the light says it is good to 100 meters. i would expect that the light should function as advertised. When I received it, i was extremely skeptical, the body of the light was very thin. Not similar to decent aluminum dive lights i have used.

It shorted out upon leaking and then on ascent (at night) I was watching it. The light was leaking bubbles OUT of the area around the glass lens. When water gets in, it gets over pressurized on ascent. It was so porous that when I opened it on the boat, there was no pop, all the excess air had been released already.

Maybe you need to read the board more. The idea of Chinese o-rings being crap is fairy well posted. Could they actually be engineered so well as to avoid internal overpressure!!! Just lucky is my guess.

I've had mine down to 100ft multiple times. I promise you the "thin aluminum" has no issue handling that depth, but the o-rings can often use an upgrade.
