POOL & SPA LIGHT LENS GASKETS
Remember when replacing your pool or spa light bulb it is very important to replace the lights lens gasket.

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.

Can I replace myself?
Yes you can replace yourself as we have a great guide on How to Replace a Pool Bulb which will walk you through the process.
My bulbs burn out after a few hours of use. What would cause this?
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.
