Hi, Jeff. This bulb is not compatible with your fixture. There is not an LED bulb that will fit the fixture that you have.

will this work with pentair orginal bulb is 12 volt - 100 watt

A  Answered on 3/12/2017 by InyoPools Product Specialist Patrick P.

Hi Warren, If your bulb is 12 volt then you would need the 12 Volt LED PureColors Spa Bulb. To make sure the PureColors bulb will work in your Pentair light fixture, you will need to double check that your current bulb has a screw in base like this Spa Bulb if your bulb does have a screw in base then the 12 Volt PureColors LED Spa Bulb will work for you.

i want to replace my pool and spa bulbs, for the pool i want to buy the RF bulb but i don't see any spa RF bulb, so how can i make it work so both bulbs synchronize?

A  Answered on 4/19/2017 by InyoPools Product Specialist Stacey M.

Hello Jon, If you have two RF Remote bulbs they may not always synchronize. Because the lamps are installed underwater and the water will block the signal in various degrees, also since the bulbs are at different distances this can affect synchronizing. Most likely your lights will also be hooked up to a light switch and if the lights are wired to the same switch then cycling through the color show with your light switch instead of the remote will ensure that the bulbs synchronize together in color changing mode. Please make sure you have housing that is compatible which is Hayward Astrolite II SeriesPentair SpaBrite Series.

My whole house has LED lights and it was time to change that 100 watt spa color!

Written on 1/23/2020 by JOHN B.

If you are handy with DIY projects, this is one you can do. Having LED lights in the pool and spa is a huge energy $$$ saver. We have our pool lights on every morning and evening now. Prior to this, we rarely used the lights.

NOTE: This light should NOT be used with a dimmer. This important information is not very obvious in the documentation.

1. Turn off power to pool lights at the breaker.
2. Layout tools on towel along the deck above the light niche.
3. Get in the pool (I will use any excuse to get in the water).
4. Unscrew single pilot screw at top of light niche.
5. Pull out light fixture and lay on towel.
7. Note location of screw and clamp holding lens in place (You'll want to reassemble it in the same position).
8. Use a socket set to loosen clamp holding lens and ring to fixture. Remove clamp, ring, and lens.
9. Remove old gasket, clean rim of fixture, replace with a new gasket.
10. Remove 500 watt bulb and replace with 35 watt color changing LED bulb.
11. Clean lens.
12. Turn power on at breaker, test bulb, turn power off at breaker.
13. Reassemble lens, ring, and clamp to fixture. Securely tighten clamp with socket wrench. Use pliers to take out some slack in the clamp ring, if necessary.
14. Set light fixture in water and test for air leaks. If a steady stream of bubbles appear, quickly remove the fixture and check the assembly around the gasket.
15. Wind cord around fixture and you return the fixture to the niche.
16. Align the fixture to the niche and replace the pilot screw to hold it in place.
17. Turn the power on at the breaker.
18. Test the light (See the directions for selecting the desired color setting or syncing with a color changing LED spa light).

Boring White Spa Light

Written on 4/15/2019 by Guest

Purchased new LED color changing bulb, gasket, and screw. Lowered water level in spa so I could reach light without submerging myself. Removed one screw to detach light assembly. Loosened retaining ring and detached lens. Cleaned gasket residue from lens and housing and replaced light bulb in housing. Reassembled with new gasket and replaced in the niche.

A couple of small issues:

1) Niche retaining screw had corroded, so purchased a replacement
2) Light housing had a dangling spring-like assembly (assume temperature sensing device). It would catch on new LED bulb while screwing it in. I used a small screwdriver to hold it away from the bulb while replacing.
3) Retaining ring was very difficult to re-install over new gasket, as the nut was at an odd angle to the bolt and wouldn't catch. Ultimately assembled ring separately then pried onto retaining clips. This took the bulk of the time.

Decided after 15+ years of my 150 W $$ eater to go with the LED!

Written on 6/5/2017 by lesis

After retro-fitting spa with a new Pentair light fixture from INYO Pools (best available price found on the Net), simply unscrewed the light fixture's lens retainer bolt, removed the white light bulb and replaced with the multi-colored LED spa bulb. Thereafter, re-fitted the fixture lens to the light fixture body and re-tightened the lens fixture bolt. Then, re-inserted the entire light fixture into the spa light niche and attached same with a screwdriver.
