Re: Any underwater lights with electronic switch?

The 1" NPT fittings work fine. There are 10 of then around this tank,
and it's been pressurized multiple times without any problems.

As for a brief description, this is a hyperbaric tank that we'll be
able to put fish into and pressurize them anywhere up to 500 psi, then
run acoustic experiments on them while they are pressurized. I want
the light so that we can see the fish when the tank hatch is closed.

But yeah, maybe the easiest way would be to just get an LED and make
my own housing for it. Guess I'll have to start doing my research.

Thanks!

NPT can take 3500PSI in my tractor's hydraulic system.

And I remember some fairly old tanks used for diving that used NPT for
their valves... Assuming they design the 1" NPT fitting correctly, 500
psi should not be a problem... I'm a bit curious what needs to be
pressurized to 500 psi and needs a light inside of it... Designing
small lights to handle that pressure is easier than designing large
lights for it... Also, whether the light is going to be exposed to
water or just air at 500 psi could make a difference in the design...
