Yes, there is a pure white LED bulb that will fit perfectly and replace the edison type bulb. It is made by J&J electronics. I have been talking with them about this and have not ordered it though because I want a color changing LED bulb that will fit the old swimquip niche. Jack with their sales told me last fall that they were coming out with the white light in January of this year and the colored one would be out sometime later. So far the colored one is not out yet .
Contact them. You can find them by googling J&J Electronics or J and J Electronics.
Hope this helps.
Several pool suppliers still carry the light kit for the old SwimQuip niche but not the bulb. You can get it by contacting J&J.
I have not been able to find the lense kit that SwimQuip use to have. No one has it. I found one but the supplier said they did not know if the lense kit would fit the original SwimQuip light.
A pool contractor sold me the Hayward Color Logic light and said it would fit hte SwimQuip niche but it would not and he will not give me my money back. Sorry contractors, I have had 4 of them so far since last fall working on remodeling pool and deck for a cost of approx 32,000.00 and had to fire all of them. I have hired the 5th one and so far he has done what he said he would.
Please let me know your results.
