Will this work in a 12 V pool light?
No. This is a 120 V lamp. A light fed by a 12 V transformer needs a 12 V bulb, so check the voltage on your old bulb or on the light's label before you order.
Any tips for swapping the bulb?
Shut off power at the breaker, lift the light onto the deck, and replace the lens gasket if it is flattened or cracked. Never run an incandescent pool light out of the water: it overheats in seconds.

Let customers speak for us
Great prices, fast shipping, great products
Haven't received yet but I'm sure it'll be great
Ordered on Saturday and we're delivered by Tuesday! Great products and great prices!
PST pool supplies are great to work with. I was having trouble finding this heat exchanger . Everywhere I looked, it was out of stock or back ordered. I contacted the manufacturer about buying the heat exchanger. They told me I couldn't buy it because I wasn't a dealer. If I was a dealer, they would be able to take the order. And make one, it would take 5 to 8 weeks. I contacted PST they put my order in and I received it in about six weeks. Fantastic people to work with. Thanks Tim
As described original equipment, thanks
Easy. Came quickly. Wish the shipping was free. I paid extra for insured shipping and it wasn’t signature required. Simply left in my mailbox.
My hot tub stopped giving a signal to trigger the heating core. I had to replace a whole motherboard and they had the perfect product and with a couple of screws. It went right right in and worked perfectly.
Worked perfectly to get our pool filter motor back up and running.
Great price and it was the exact fit for my TM26 Filter.
Easy to install it took 20-25 minutes and it was back up and running with no issues!
Work perfect
Same pump and motor I needed for my pool setup and would’ve been great if I didn’t have to tear apart the new one to install old part. Best price I found anywhere too.
Great company to work with!
Came in great condition my kid loves it, fit perfect hes 6 and got a medium.
Order received. Thank you
