To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Finally found the light bulb i will stick to. Tried the branded ( GE, Phillips) CFL and even LED bulb. There isn;t too much option for 4-pin configuration. I like the color 2700K Warm White, the best. This is the cheapest light i can find offer with this color.
Even the most expensive bulb, which cost 3-4x as much as this, it won't last even half the advertised lifespan. I have ~20 lights throughout the house and every year, i have to replace 3-4 on average. This bulb last about the same as the more expensive bulb but cost 1/4 the price.
No flicker, instant on, true color (for warm white) and cheap. What else not to like?
Our condominium building has fixtures in public areas that take these weird CFL bulbs, so these were ordered to replace some that have failed. When our association has sufficient funds the plan is to replace the fixtures with ones that take LED bulbs that screw in, replacing these bulbs that are 4-pin snap-in style and require ballasts in each fixture. LED's are more efficient and will last longer.
These led lamps were purchased to replace compact fluorescent lamps in the fixtures in my church. About half the cfl lamps had failed due to end of life or bad ballasts. Once we figured out how to get to the ballasts and bypass them, the led lamps were easy to install and work very well. We've had them installed for over a year now and none have failed. Hopefully, we won't need to replace them for several years.
Perfect replacement at a great price. Quick delivery and well packed. Follow up after a month of use the bulb became dim and had to be replaced. The bottom glass tube started turning dark. Box states that bulb lasts 11 years but my first bulb only lasted several weeks.
We have some sconces in our hallway and staircase that take unique fluorescent bulbs. I searched lamp shops, Big Box stores, hardware stores, and online bulb suppliers, but could not find an exact fit. Amazon had the correct bulbs at a reasonable price, that were just right. I knew that if they weren't, I could send them back and keep looking. I am happy that I did not have to!
I always use LED bulbs when possible. But, LEDs for these sockets are not available from most brands, and are expensive. These work fine, and are nearly as energy efficient. Make sure you get the right base, as there are two very similar, but incompatible ones.
I ordered these as a replacement for 20+ year old fixtures. I was nervous about whether or not they would work and so I only ordered a few. They worked wonderfully and the light (as chosen) was a warm glowing color in the wall sconce. I immediately ordered enough to replace the rest of the burned out bulbs. Super happy with this product.
I was shocked when my original bulb burned out and I opened the casing and saw that funny looking bulb. I ordered a four pack from amazon and it came quickly. My problem is it doesn’t fit my system. Count the pins. I suppose if I had ordered the correct one it would be good. My fault entirely.
They are the correct type of light bulb, but these would not fit in the socket. The only difference I could see was that the triangle shape on the side, was slightly bigger than the bulb I pulled out. I was afraid if I pushed harder, that it would break! I bought them as backups and now I can't return them because its been too long. They probably work just fine, but I"ll never know.
I assumed these CFL LIGHT BULB 2700K would be a Warm White as in the description. I should have tried one in the kitchen ceiling sooner. The light is NOT WARM at all. The light is a BLUEST BRIGHT LIGHT and very unappealing. I should have sent them back for a refund or exchange.
