Was delivered in 3 days, didn’t have to waste couple of days driving around trying to find right bulb!

Works as intended.

burned out within an hour, dont know if it was the appliance or the bulb???

Worked great

Worked perfectly for my outdoor Xmas fiber optic display requirement.

The bulb works great as promised. The contacts were a tiny bit longer than the one I replaced, but it wasnt a problem.

Two pack of bulbs, but one was broken.

Purchased to replace bulb for fiber optic pumpkin. Manufacturers bulb lasted 20 holiday seasons. Finally burnt out and replaced with this amazon bulb.

We have an electric fiber optic Jack-o-lantern that we have enjoyed for years. The lighted fiber optics stopped working, so I took it apart to see if it could be repaired or parts replaced. It was discovered that the bulb was burned out, so I researched Amazon and located the bulb that I needed. Of course the bulbs came in a two-pack. I only needed one bulb, and I would have a spare if in the next 15 years the bulb would burn out again. FORTUNATELY there were two bulbs in the package because one of the bi-pin bulbs came with only one pin (see photo). The other bulb worked perfectly and is lighting the Jack-o-lantern as I write this review. I FIRST sent an email to the seller requesting help with a bulb replacement but never got a response, so that I why I am giving the review a low score. All I requested was a bulb to replace the defective one. POSITIVE UPDATE: Oct.21,2019 Just received a replacement for the defective bulb. Seller never received my original complaint that was first directed to them, but did reply immediately when they read my review. Kudos to this seller. They totally stand behind their product, and have great customer care.

Bought to replace bulb in fiber optic Christmas display houses. Dont know brand, but houses are ceramic with spinning motor inside. Light shines up on spinning color wheel. These bulbs actually brightened the lights a bit.
