Replacement Light

I have a Hayward Starlight - SP543-L that has gone dead. I would like replace the light but am not sure what will fit without replacing the Niche. Any ideas?

Welcome to The Forum!

It's usually just the bulb that needs to be replaced.

MOST builders are savvy enough to leave a few feet of extra cord in the niche so you can unscrew the retaining screw and haul the light housing up onto the deck. Make sure the light won't turn on when it's out of the water!! (retaining screw should be phillips-head and located at the top center of the retaining ring)

Check the bulb and get back to us. You also need to know if it's 120 volt or 12 volt. If there is water in the housing, you'll need to completely dry it and get a new gasket.

Check it out and let us know what you find - we can help you with this. :)

I can confirm it is not the bulb....I had ordered a replacement bulb and was in process of replacing it. It is a 120V light. I have 120V as the junction box but nothing at the light. Internal to the light there is a "metal" cap that appears that it covers a "circuit" that would trip the breaker if water was in the light cavity. The cap easily (too easily) popped off and i found the "circuit" is rusted beyond repair. (Obviously some water had gotten it at one time - I should note that the light cavity was dry when I went to replace the bulb). Note - the retaining screw is slotted....I would like to replace the light housing. But since the Startlight series is old, I cannot find a replacement part. I am looking for advice on what replacement assembly will fit in the existing niche.

bump - any thoughts on what will fit as a replacement light assy?

I'm not 100% sure but any light should fit the existing niche, even between brands, the niches are fairly uniform and will accept a new light housing.

Have you talked with Hayward?

If you need help removing the old housing & cord and installing the new one - or, if you actually need the niche replaced - get back to us.
