I have two lights about 3 feet below the water surface. One of them turn on
and one of them went off recently.

I had the electrician who was working on my remodeling take a look, and he
opened a junction box near the pool, and there is power at the junction box,
so it is either the bulb or the light fixture is bad.

He told me normally swimming pool lights are low voltage, but in my case,
the wire going to the light is not low voltage but 110v. He said either the
light fixture has a built in low-voltage transformer, or when they put the
light fixture in back in the 70s, they used a 110v light fixture, and I need
a specialist that deals with pool lights to examine it.

Do I need to hire an electrician that is specialized in pool light fixtures?
or do I need to drain the pool down below the fixture level to take a look
myself?

My water table is very high being in Miami, I was told I cannot drain it or
it will crack, what if I drain my pool to half full (25000 gallon pool) it
will not crack right?

Thanks,

MC
