POOL & SPA REPLACEMENT LIGHT BULBS
This tandard flood lamp will replace a 500 watt 120v/130v bulb in many common pool lights including the Hayward Astrolite and Pentair Amerlite. Our bulbs feature thicker filaments and glass along with heat shielding to extend bulb life.
* Dimensions may vary slightly
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. Click here for Pool Light Lens Gaskets
For additional pool & spa light bulbs
Have a Hayward Light Fixture in an older in ground pool. The old bulb expired at the end of last season. Pulled it. It is a 'GE Pool Light, 500w, 120v' bulb. Does not say 'flood' on it. A label on the body of the light fixture says, 'Hayward Pool Products, Fix Mod: SP-583-L, Watts 500, Volts: 115, Bulb Type: R40. Will this bulb fit in my fixture?
Hi A.D., Yes this is the proper replacement bulb for your Hayward SP0583 light. We would also suggest replacing your Hayward Lens Gasket when replacing your bulb. If you would like to upgrade to LED Color Changing then you can go with the PureLine PureColors LED Color Changing Bulb. We also have this Video on How to Replace a Pool Light Bulb which may help when you tackle this project.
My bulb has a hole in the bottom of it and there is a copper wire that goes into it from the light housing. Can i use any bulb? I have never seen a bulb with a pinhole in the bottom. This is for an inground pool light. Thank you!
Hi, Nancy. Please upload pictures of the fixture so that we can see what you're referring to and identify your fixture housing.
Do I have to drain the water from the pool below the light fixture (120V, 500 W) to replace the bulb?
I have an American Products Inground Pool Light with a Cn-5 submersible can. It originally had a 120v 400W bulb that finally burned out. Can I use a 500W replacement Bulb with a new gasket?
Currently have 500 Watt, 120 volt light (Astrolite SP0583L30). What LED light would be comparable to what I have now.
What do i need to change from regular 500 watt bulb to an led bulb.
Will this light bulb work on a Hayward Astrolite?
Yes, this bulb does work on Hayward Astrolite, as well as other makes and models of pool lights. The most popular of these lights being Pentair Amerlite, Hayward Starlite, Haward Duralite, and Sta-Rite SwimQuip Lights. Click here for a full listing of our >Pool Light Bulbs & Spa Light Bulbs.

Best Price and fast shipping with GREAT Tracking!!! (USPS) You will see all over the web that the Bulb almost ALWAYS breaks. Sure enough - it did!!! They quickly sent me a replacement Bulb - but when it arrived it was a 300 watt instead of a 500 watt!!! Very quickly they sent me the REAL 500-watt bulb. This all took place in about 10 days. GREAT JOB!!!

This was a great low cost replacement for the underwater light in the pool. Product was exactly as advertised. Website was easy to use. The light bulb arrived quickly and in perfect condition. Website also had easy to follow instructions to replace the bulb. I also ordered a rubber seal around the light based on the instructions on the site.
