1) My Lights are tripping
the Circuit Breaker.
If your light or lights are tripping the circuit
breaker, this is an indication that you have some type of short
circuit. You will need to inspect each light on the circuit for
a possible leak. If you find one light which has some water in
it, this would more than likely be the cause. Electrical issues
can be the most difficult to find and fix. Sometimes it is
obvious what the problem is, a broken lens, a cut cord etc. But
other times it can be extremely difficult. If you have multiple
lights on the one circuit, Disconnect all of the lights in the
main junction box. Then hook each on up to the power separately
and test the circuit. The circuit will trip when you find the
offending fixture. Caution: sometimes the
lights will not trip the circuit when they are out of the water.
So you may need to test them fully submerged. With a lot of
patience, you will find and fix the problem.

2) Does the light have to
be underwater.
Yes, the light has to be
fully submerged to operate. If the light or lights are operated
with the lens exposed out of the water, it will get extremely
hot and break the lens. It will possibly burn out the bulb
also.

3) Can I replace the
cord.
No: you can not replace
the cord. The only part that can be replaced in the potted can
assembly is the porcelain bulb socket.

4) What type of bulb does
it take.
The Model 4600 light fixture, required a 200 Watt
120V PAR46 bulb with side prongs. They are available in NSP
(narrow spot) of MFL (medium flood) with NSP being the most
popular.

6) Do I have to replace
the gasket.
The lens gaskets seem to last forever, but if it
is cut or damaged in any way we would recommend that you replace
the gasket.
