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.
These don't fit since the base tab are centered on these. My Panasonic bath vent/light takes the 18 watt or more version where the tabs are offset. I got these cheap CFLs to fit by removing the tabs with my Dremel. Would have given these higher ratings except for the fact that after less than two weeks' use these cheap CFLs were already flickering. As cheap as these are, I'd rather pay more next time for Sylvania bulbs at least I can get more life out of them.
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.
I've bought many CFL bulbs in my life. These are rated as Color Rendering Index 82, which isn't a very high number, but I think they might be even lower than that compared to other bulbs I've bought. The light they give off is seafoam green, like the worst kind of subway corridor lighting you'd see in a '70s industrial era Soviet film. Do not use these anywhere there are people or food you want to enjoy the sight of.
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.
Exact fit for our light fixture. Existing bulbs were near end of their service life--would take a minute or two to go from dull glow to full brightness. Ordered these bulbs that arrived ahead of scheduled delivery date, popped them in in less than a minute and, voila, instant bright light at the flip of a switch. Ordered the four pack so that I have a standby replacement set to use in a year or so. Great value, very satisfied!
I had not seen this bulb before (closet dome light that came with the house) and certainly don't have any on hand. I priced in comparison to local and big box stores and this price won. I have lived with the previous bulb for at least 6 years so as far as longevity goes, it'll likely be quite awhile before I know for sure, so far so good!
My light bulb burned out after a few years, and these bulbs showed up as a suitable alternative on a search. I ordered them because the dimensions were correct, and a photo on the site matched the base of our burned out bulb. Got these in the mail very quickly, and it fir into the socket just right and the light is good.
Previous lights (all 4) in our bedroom lasted at least the 3+ years we’ve lived in this house. They started going out, so I replaced them all with these four months ago. Now, already, one is dead. I wanted to replace them all with LEDs, but too hard to remove or bypass the ballasts. Even so, I wish I had done it!
