POOL & SPA LIGHT LENS GASKETS
Remember when replacing your pool or spa light bulb it is very important to replace the lights lens gasket. After long use, heat, and harsh chemicals, the old gasket is probably compressed, and if it doesn't fail immediately, it might fail before the next bulb change. Click here for Pool Light Lens Gaskets

First time replacing bulb for light fixture. Pic of cart and fixture housing. Heading in the right direction?
Hi Joe, Yes those are the correct items in the shopping cart of your photos.
Does the light come with the lens gasket, if not where do I find it?
Hi Graciano, these do not come with the lens gasket. Could you send us a few photos of the light fixture or the model number? To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation.
Is this bulb a replacement bulb for Amerlite underwater light - I was looking for product # 79102200. a 400- watt r-40 medium base bulb.
Also I believe the current bulb is fixture is punched saying bulb is a 500 -watt bulb, but the bulb I pulled out doesn't look like the 500 watt bulb on your site. The shape of the bulb I pulled out looks like this 400-watt bulb, using this in the fixture is Ok?
The shape of this bulb is different from the original however is a compatible replacement bulb for your original part number 79102200.
Is this bulb the correct one for this housing. I don’t see you have a 300w version?
That shows a non screw type bulb my fixture takes a bulb that screws in..
Garett, The fixture label has T3 R7S as the bulb type, this 400W, 120V, R40 bulb can be used with your fixture.
I need a new pool light. I removed the blub. On the inside the label reads 400 watts 120 volts R-40 bulb type. It also reads model 7884XX, 7844XX, 7894XX... could you please tell me which blub and casket I need
I need to replace a light bulb in a 15 year old pool light. No label left on the light fixture.
American Products Co is embossed on the approx. 8" diameter glass lens. The niche is part # 792067 (Pentair?).
Circuit is 120V.
Must the new bulb be exactly the same watts as the old one or could I just use a 400W bulb?
I assume the gasket is the 8 1/2 inch version such as LPL-G-P or 3525-07?
I love the details you give on your website! Thanks!
I have an American products underwater light(wet niche type) model is R-400 BCL. the gasket I see on your site is 791016. the bulb is an R 40 reflector bulb p/n 993650, not sure which bulb that is you have listed. other #'s on the light are 98708400 & L 777985. thank you for your help.
Hello, Steve. The part number for R-400 BCL cross-references to the Pentair Amerlite Pool Light and the part number 98708400 cross-references to the American Products - SpaBrite & Aqualight. I best recommend verifying the voltage and watts on your current bulb or the casing of the fixture. You may find this link helpful as well.

To replace light bulb in pool light: I shut off the power at the circuit breaker. Removed the one screw holding the light in place and attached to the side of pool. I then proceeded to take the light completely out of the pool.
Removed all the screws holding the light cover in place. Removed the old light bulb and placed new bulb. Be sure to change the gasket for your pool light to insure a tight seal ( this product also sold by Inyopools.com). Tighten all of the screws firmly and placed light back in pool. Turn on circuit breaker.
