After years of dreading turning on the power hungry 300 watt bulb used in my pool's waterproof surround, I bought a color changing LED. I found myself leaving it set to blue, or maybe a program doing a subtle blue-to-purple shift. I really liked it until it died a few months later. Then his successor died a little over a year later. Although the seller of the color changing LED replaced the first light, the second one cost me $60+. Not to mention that accessing the bulb and replacing it is a pain. So I decided on this blue pool light bulb having already used the red model in my hot tub with excellent and trouble free results. Red is perfect for hot tubs; Red light doesn't penetrate well through water, so it's not very bright there. Blue light transmits better, so I tried this 10W blue LED in a pool. It looks great, is bright but not too bright, is inexpensive and should last a lot longer than the color changing bulb it replaced. And because it's a sealed lamp (as opposed to a color-changing lamp with exposed LED elements), it must withstand any moisture inside the sealed housing. I am happy.
