Hello I want to raplace the bulbs of my hayward SP0590SL100 Astrolite which ref should I buy?
Hello Yaber489 - The Hayward Astrolite II SP0590SL100 is a 100w 12v spa light. We do have a color changing LED bulb for that fixture, the PureLine PL5816.
The lens gasket should be replaced when you replace the bulb. The gasket for the Astrolite II is part number SPX0590G.
