POOL & SPA LIGHT LENS GASKETS

Remember when replacing your pool or spa light bulb it is very important to replace the lights lens gasket. After long use, heat, and harsh chemicals, the old gasket is probably compressed, and if it doesn't fail immediately, it might fail before the next bulb change.

My bulbs burn out after a few hours of use. What would cause this?
 Reply

A  Answered on 1/21/2013 by InyoPools Product Specialist Patrick P.

My first guess would be to check the voltage. If you are getting anything more than 12v to the light, it will run hotter and burn out quicker.

Will this Bulb fit and work with Hayward Astrolite Model # sp0581s15. I think it does but want to make sure.

Hello Orlando, yes the Seit NA700 bulb is compatible with the Hayward Astrolite fixture. I recommend confirming your voltage is 12 volts before placing the order.
