GU24 Light Bulb 4000K Daylight A19 LED Bulb for Ceiling Fan,Cotanic 2 Prong Light Bulbs with GU24 Twist-in Lock Base 9W 60W CFL Replacement,900LM,Non-dimmable,4 Pack

Bulbs were used for a bathroom fixture and work much better than the old bulbs. Nice and bright. Fit perfectly.

One of the CFL bulbs in my ceiling fan had burnt out and I replaced them with two of these bulbs. They have a nice warm white glow and I haven't noticed any flicker. I'm not usually sensitive to LED bulb flicker though. The CFL's were kind of a tight fit and I had no problems getting these bulbs to fit in the space.

I purchased this as a replacement for a defective 1200 lumen fluorescent twist lamp in my bathroom vent / light. The twist lamps that came with the ventilator were nice and bright, but took a few minutes for them to get to full brightness. I was looking for an LED replacement to eliminate that warm-up period, but nothing larger than 3.75" long would fit. This lamp, at 900 lumens, was one of the brighter at that length, so I chose it as the replacement. Knowing LED lamps have a higher CRI, I thought it would be comparable to the 1200 lumen twist lamp, and it has worked out well. The light output and color are similar so it's hard to tell the difference. It's just been installed, but I expect the life to be longer than the fluorescent, so I'm very please to this point.

Great Replacement - LED, brighter, easy to install, longer lasting

The bulbs are easy to remove and just as easy to install. The last bulbs we used in this ceiling fan were soft white so they never got very bright and being fluorescent they took their sweet little time lighting the room, these you turn on and they’re going to be bright immediately, don’t have to wait! It was also a good price!

My closet bulb went kaput. I thought no problem, I have so many bulbs in stock. I opened it up and of course it’s the weird two prong kind. Thanks for Amazon, I could place a order and get it next day. The bulb fitted perfectly and has a nice, soft but powerful glow. Hope it will last and if not I have 3 more.

The bulbs worked great.

4000K color. These fit as the should. I couldn’t be happier. Thank you Cotanic!

Just a few days ago, I ordered 4 bulbs Gu24 2700K from Amazon through a different seller. I was so disappointed because out of the 4 bulbs, only one is working well. The other 3 bulbs will take a bit of time to turn fully bright. Now I would have to go to a Purolator location for the hassle of returning all these 4 bulbs. I am so glad I found this Cotanic brand. I tested all 4 bulbs, and they are working great. In my bedroom, I normally use 2 pieces x 2700K bulbs. With one Cotanic 2700K bulb alone, my room is already well lit. I don't need to use 2 bulbs, which means I have more spare bulbs and I would even save on electricity cost. The product was delivered promptly, and it came in a well-designed box/professionally packaged to avoid breakage. Cotanic brand is highly recommended. You won't regret it.

Bought these bulbs around 6 months ago. All the light fixtures in my apartment building are GU24, and it's so hard to find GU24 bulbs in store. Even when I find them in store, they're dirty expensive, so these bulbs on amazon are lifesaver. These are much nicer than the CFL bulbs and last much longer too. I ordered the 4000K and they're a really nice soft white - not too yellow, but not harsh white either. Will be ordering these in the future.

The bulbs delivered on time. Bright and perfectly fit as described . I am genuinely surprised. Thank you.

Decided to give these a shot after my old CFL bulbs died. Needed brighter than 3000k, but not as bright as the 5000k. Took a chance on these and they did not disappoint. Easy to install and gave my way some much needed light that the 3000k bulbs couldn't do. Their value is definitely worth it as other bulbs go for 10-20$ each. Highly recommended to all!

I replaced compact spiral GU24 CFLs with these. CFLs take a while to warm up when they are cold and they are not very bright. These are a great replacement with no warm up time. They are a different size and shape, though, so you cannot use the plastic housing / cover that comes with those. You would need an LED replacement specifically for the spiral CFLs and they are way more expensive. I have the housings but don't need them so these are great.
