Last year I replaced my pool lights with bulbs from this company, but were HP16LED, a slightly smaller version of the one you're looking at. I don't see the ones I used on the website, but the bulbs have worked perfectly. I wouldn't have a problem recommending the bulbs or this supplier. Let me know if you have specific questions...
I replaced color changing LEDs that went bad after about 5 years, but found after the novelty wore off, I left them on white almost all the time.
