What is this bulb (20 year old deck light)?

[Jordan]

Hello -

Can anyone help me identify this bulb? It's 111mm wide and has screw terminals on the back. It's from my deck light and I need a new one. The boat is 20 years old and french. The glass bulb clips into the plastic fixture.

Thanks
Jordan

I THINK it is a GE par 36.

Google sealed beams with screw terminals.
There are several but the par 36 is just about 4.37" (111mm)

That is a PAR36 reflector lamp. Assuming you run 12 volts, Grainger.com has them in stock in 12, 20 and 50 watts. They also have a 28 volt version (for 24 volt systems).



Those lamps are used in tractors and industrial and construction equipment, and are fairly common if you aren't picky about wattage and beam pattern.

If it's a PAR36, there are LED replacement versions available.

I agree with Calistov42, it looks like a PAR36 sealed beam bulb. They are pretty common in spreader lights and other flood light applications. Just Google Par36 bulb and you’ll find plenty of them.

Amazing. Got an LED one for $15 on amazon. Thanks everyone!

In retrospect it's ridiculous how long we've been living without a deck light.

Definitely a PAR36 lamp. I had to buy two similar replacement lamps for the spreader lights on my boat. Unfortunately, I managed to lose one of the v-shaped internal snap rings that retains the lamp in the (42 year-old) housings, and while the lamps are readily available in filament or LED form the snap rings for that old metal shell type are unobtainium. I have a friend who says that he can 3-D print one for me, but I may just take a piece of 4-5mm teflon sheeting and make my own replacement using a jigsaw and Dremel tool. The other alternative is to replace both lights with new LED floods in modern waterproof housings which would probably long outlast my ownership of the boat.

Have those for all my landscape up-lights. I would replace the halogen versions about every 18 months. Finally bit the bullet and went with LED-going strong for 4+ years in below-grade well lights that fill with water, mud, and leaves on a regular basis.

Yes, they are commonly used in landscape lights.
They are not a durable light. Get the LED verson of the PAR 36. They cost more than double the halogen but will last much years longer.
I have them in my Mom's landscape lights and replaced the whole system for what replacement halogen bulbs cost.
