What is the total diameter of the light?
Michael B on Apr 27, 2016
BEST ANSWER: Out side diameter of light ring
Can the case be replaced keeping the existing cord?
David L on Nov 23, 2017
American Products company inground pool light on the glass 3915 120 v 300watts and I want to switch to LED ....which would be a comparable LED bulb ?
Stefan K on Jun 10, 2019
What is the diameter from edge to edge including the stainless ring?
Michael B on Apr 27, 2016
BEST ANSWER: 10 inches across. 7 3/4 deep from pinnacle of glass to back of shell.
Any 75 ft cord? My distance is 55 ft
A shopper on Jun 3, 2017
BEST ANSWER: I only needed 15ft, due to my wiring being run through conduit buried near my pool. I would purchase the light light with a long cord, and cut to needs for first time installation. Less chance of water intrusion. I grounded at house mounted switch, this way it is grounded along with the house, not at the buried junction box.
Why is it rated 120 volts, isn't it on a transformer that knocks the voltage down to 10 v. or so?? thx
Chris A on May 8, 2017
BEST ANSWER: Surprisingly many of the systems are standard 120v. In fact the bulb inside is often just an everyday screw in light bulb. It does have a grounding system. However my light was full of water and on and no fatal hazard!!rather than replacing the bulb and trying to reseal, I would just get a new sealed unit.
can an amerilite be replaced with a pentair fixture?
A shopper on Jul 10, 2017
BEST ANSWER: It's just a light fixture, if it fits in the basin of your pool, it's only held in with one screw, just do your measurements before you buy, and good luck
Can you use dimmer switch with these lights?
A shopper on Nov 15, 2016
BEST ANSWER: ok what I did was take the big bulb out---went and bought a "dimmable"L.E.D. light bulb -----it is rated at 10 watts----but produces a 200 watt effect without a big electric bill---plenty of light for the pool-since I have the on/off switch in the living room wall to light up the pool----I simply put a dimmer switch in the regular out lit where the "switch" used to be and ------presto a totally 100% dimmer light.-------you can do it to the out side switch also-----might have to re-design the box-or replace it with an in house G.F.I.switch-----dimmer.
hope this helped.
I replaced my 500 watt incandescent light in my Pentair Amerilite with a J&J Colorfast LXG and replaced with new gasket. No air bubbles after putting back in niche and leaving on for 10 minutes as instructed. First day, all worked perfect for all lighting options. However, on second day, I cannot get light to come on. The circuit breaker is not tripped. I have a new GFI outlet on the pool light j-box which I reset to ensure this is not the problem. I have turned light switch off and on for many different options all without having the light come on. What can I do to get light to come on?
John I on May 29, 2018
BEST ANSWER: Have you confirmed that there is power going to the fixture? If so, I'd suggest removing the fixture from the pool and testing the bulb in another socket that's known to work. I would also test the GFCI. Good luck!
Can I use a transformer to lower the voltage to 12v?
Dennis F on Jun 20, 2017
BEST ANSWER: I don't think so, It's a 120 volt light, a 12 volt transformer would only send 12 volts to the light which wouldn't be enough voltage for a 120v light.
whats the dimensions of the smaller one for spa light? i have an existing niche of 7 3/4 inch opening?
celcon electric on Nov 26, 2016
BEST ANSWER: The smaller spa size lights are 6" wide.
do i have to drain pool to replace this light?
A shopper on Nov 22, 2016
BEST ANSWER: No I did not. I tape the end to keep it from getting wet as much as possible. I tied a piece of string to the end of the broken one and pulled it out. Then I tied the string to the new one and pulled it back thru. If you go on YouTube there is a video.
Do you have the pentair light fixture in 400 watt 120 volts 30 ft?

It's just a light
Good value for this light, put an LED light in right a away for color effect, easy install, local pool store wanted 400 dollars, and it's the same light, would recommend this one for any occasion, just remember when shopping for a pool light, it's just a light bulb in a case, not a Pink Floyd concert
