I have a pool built in the 80 and light does not have any tags to tell me the brand. Would this light work? I can read 500 watt 120v r40.The current light is recessed in the wall niche and is about 9 1/2 inches around with 1 screw at the top to attach it .Some lights look like they sit inside the niche but the light ring is on the outside of the niche attached with screws.Would this light work?

does the fixture come with a bulb?
shopper on Apr 14, 2021
BEST ANSWER: No, but the bulbs are not that expensive
Is the lens clear or blue?
Frank H on Apr 20, 2021
BEST ANSWER: When I ordered it the standard was a clear light, but you can purchase a blue lens to cover it. My pool is a light pebble blue, so no blue light lens was necessary. It was easy to install and works perfectly.
Is it ok to put a 400W bulb or an LED bulb in this?
A shopper on Sep 21, 2020
BEST ANSWER: Yes it is. The LED will take less power however the spectral color of the light will not match an incandescent light that may already be in the pool. You may want the lights to match.

Quality Light!
Replaced my 18 year old Pentair Pool light. The new light has some improvements over the old version. The light housing has a raised lip to help seal the light against the lens gasket which is nice. Installed a J&J LED Color Splash bulb, love it!
