What is the replacement for No Y-063073 7878 XX 75 watt 12 volt MR-16 Model 792066 OR?
Tim H on Feb 21, 2017
Does this light work with 10v, 16v and 19v? Or have to be exactly 12v
thank you
Jalinos B on Jul 12, 2020
BEST ANSWER: I believe it is rated for a certain voltage due to the element. If you pump in 16v it may be brighter than normal and burn out sooner, same with lower voltage as 10v it may burn dimmer and burn out sooner due to build up on the element. I would stick with what your transformer emits for load voltage. Some transformers do vary in voltage of the load requirements. Check your transformer.
I had this light installed professionally 2 years ago for my in ground pool.
Just recently the light quit working, so I shut off all power sources and brought the light housing up and out of the pool. I bought the exact same 300 watt bulb and after installing the bulb and reconnecting the power it blew. There was a disc inside the light housing which resembled a buss or fuse and its blown. What could I have done wrong? Please advise and thank you.
If it means totally replacing the entire light and housing I may opt for an LED light instead.
Dan on Nov 28, 2015
BEST ANSWER: There is a transformer on the side of your house probably where the switch for the light is.converts 110 ac to 12 volt DC .your pool bulb is 300w 12volt Dc if the transformer is bad ,that could be the problem.
Does this work with a Hayward Transformer and niche?
A shopper on Jun 4, 2020
BEST ANSWER: Most transformers have different voltage selections to match what you are connecting such as pool light or lower voltage access lighting.usually 12, 13 or 14 volt. Brand name usually doesnt matter. Match the output voltage.
What is the dimensions of the housing on this one'?
Bill H on Sep 5, 2019
BEST ANSWER: The face ring on the light is 10.12" wide and the depth of the light is 7.72".
I have two of these 12v lights 300w with 50' chords installed and ready to be wired to a transformer. My pool guy indicated I need a 300w transformer but what I have read leads me to believe I need a 600w to avoid reduced output in each light. Suggestions?
A shopper on Sep 29, 2016
BEST ANSWER: I Only have one light and it works very well
I have an old (1980 vintage) Amerlite pool light which works fine with an LED bulb and no leaks. I would like to get a new stainless steel face ring for cosmetic reasons
, but the old model has 8 screw-down tab clamps holding the housing and the face plate together. The new ones I can find have a "universal clamp." Will the new face plate with universal clamp work with the old housing?
Tom W on Sep 25, 2016
BEST ANSWER: Slim maybe. But that light is obsolete and sooner or later you WILL change it out. Just do it now and get a color changing fixture. Its worth the little e extra cost.
Do you have a lite with a 50' cord?
A shopper on Jan 12, 2016
BEST ANSWER: no it did not have a 50 foot cord.
is this hook at the bottom and bolt at the top?
A shopper on May 23, 2019
My light diameter of the glass is 7 3/4 inches. What size is your cover for the one I clicked on?

Phenomenal Service, Availability and Price.
I ordered a Pentair Amerlite - 300w, 12v, 15’ cord Pool light #78431100 online on a Friday morning and received it Saturday, the next day. What astounded me was that Pool Supply Unlimited is located in California and I live in Florida. Pool Supply Unlimited's supply chain is phenomenal. This model light is not that easy to find, but they had it available in stock. To top it all off, their price was about 30% lower than anyone else and delivery time from anyone else was a week to ten days.
I am totally 100% satisfied. Great job. I definitely would recommend Pool Supply Unlimited to anyone.
