Does this light also come with a bulb or do you buy it separately?

A     Answered on 6/20/2016 by InyoPools Product Specialist Patrick P.

Hi Ana, Yes the bulb is included with this fixture.

Hi I changed all gaskets and new bulbs RW40 300w bulbs in two lights. One of the lights gets about 1.5 inch of water inside no matter how many times I change the silicone gasket. Glass is not broken and not dents on the edge of housing where gasket sits. Where is this water getting into the light from? the electrical cord? Also both lights look very dim? is the water causing an issue inside the housing that dims the light?

A     Answered on 6/16/2015 by InyoPools Product Specialist Lennox H.

Ray, The only other thing that could be the issue id the Unitension Wire Assy. (79111000), is that not securing the fixture properly it can let water into the fixture.

A     Answered on 4/21/2015 by InyoPools Product Specialist Lennox H.

Michael, Yes it can, you'll also need a silicone gasket. LED Bulbs,Gasket
