Hi Epsac, Could you send us a few photo's of your bulb? It would be helpful if you could put a measuring tape in the photos showing the width of the bulb and the depth, also a photo of any labels would help us determine if this will work for you.

how do you control changing light patterns?

It is controlled by the light switch. Every time you turn it off and on it goes through the different modes.

Hi Terry, The PL5816 bulb is compatible with the Hayward SP590SL fixture. You will also need to replace the Hayward Astrolite II SP590 Series Lens Gasket (SPX0590G).

Would this work with an American Products 7810XX housing? Right now it is connected to a dimmable switch, but I can change it to a standard switch if necessary.
 Reply

A  Answered on 6/4/2017 by InyoPools Product Specialist Patrick P.

Yes, this bulb will work on the American Products 7810XX housing, however, you will need to double check if it is 12V or 120V. This bulb is 12V and here is the 120V PureColors Spa Bulb. None of the LED bulbs are designed for a dimmer so a standard light switch would need to be installed.

I plan on replacing my spa (12 V, 100 W) and pool (12 V, 300 W) incandescent lights with LED Color Changing bulbs. The existing spa light is Hayward Spa Astrolite II 100W 12 Volt for a Hayward Model SP0590SL. The existing pool light is Hayward Astrolite 12v, 300 Watt for a Hayward Model SP0581100. Please provide the following: 1. Part numbers I should use for the spa and pool LED changing bulbs. 2. Part numbers for the spa and pool gaskets I should use.

Hi, Ernie. You will need the PL5816 (bulb) and SPX0590G (gasket) for the Hayward Model SP0590SL light and PL5808 (bulb) and SPX0580Z2 (gasket) for the Hayward SP0581 light.

I plan on replacing my spa (12 V, 100 W) incandescent bulb with an LED Color Changing bulb. The existing spa light is Hayward Spa Astrolite II 100 W 12 Volt for a Hayward Model SP0590SL. INYOPools has recommend the PL5816 LED bulb which is a 5 W LED. I was wondering, given that the niche that encloses the bulb is air/water tight, how is the LED bulb cooled. Will there be any heating issues with the LED bulb. Will the LED bulb generate less heat than the 100 W incandescent bulb.

Ernie, Any pool light bulb is kept cool by the water surrounding it. LED bulbs run cooler than a standard incandescent does.

I have a 300 VA, 120/12 V transformer for my spa and pool lights. Is this transformer adequately sized to power a 5 W, 12 V spa LED AND a 35 W, 12 V pool LED at the same time.

A  Answered on 8/5/2017 by InyoPools Product Specialist Alex V.

Ernie, Yes, a 300 watt 12v transformer can power both bulbs.

I have a spa bulb in my pool I want to replace with led color changing bulb it’s a 12 V should I use 35 watt or five watt ; Will a 5 W light the pool up as well as a 35 W and do you carry 35w

A  Answered on 4/5/2018 by InyoPools Product Specialist Megan C.

The model of the fixture will determine whether or not a spa bulb or a pool bulb will fit in the fixture housing. The spa bulb is much smaller than the pool bulb, it is best to provide the model or series number of the fixture to determine if the bulb is compatible with it. Please note, you will also need to replace the housing gasket.

I purchased this 12v color changing LED to switch out the Pentair Spabrite incandescent light in my pool. The incandescent works in the fixture, However, the LED does not. Any clue why? My transformer is 12V 100 watts.

Hi. Double check to make sure the bulb is installed properly, screwed in all the way and that you're getting 12 volts at the socket.

Hi, Tom. This bulb is compatible with your fixture as long as it's a 12 volt fixture, if it's 120 volts use p/n PL5817. You will also need one of the Lens Gasket - 79108500 (OEM), LPL-M-G-P (Heavy Duty) or O-344 (Generic).
