JandCase BR30 LED Flood Light Bulbs, Indoor Flood Light Bulbs, E26 Base, Dimmable, 11W(65W Equivalent), 5000K Daylight White, 850lm, UL & Energy Star Listed, 6 Pack

These lights are a really rare find and are true high quality low blue output RG0 LEDs. High quality/super high CRI, low power, and all at a fairly low price. The only real way to know how good they are is to measure them and they deliver beyond expectations.Results using Sekonic Spectromaster C-800-U:3000K rating: 2891K, CRI/Ra=98.2, TLCI=98, R9=89.6(See pics for screen shots of measurements…quite incredible.)Power consumption is as advertised at around 10.7W at 100% (not dimmed). BTW, they dim great and the color measurements stay consistent across the dimming range. I verified that with my spectrometer. There is no problem dimming and I have seen no flicker problem. BTW, most flicker issues with LEDs is not related to the lights, but a poor neutral connection to (or inside) the power panel or an incorrect/incandescent dimmer being used.I haven’t measured the 5000K versions, but I don’t want those inside my house as 5000K is good for garages or work surfaces (not for relaxing as it will keep your eyes nearly dilated/pupils wide open)…3000K is perfect for most spaces. It would be nice if there was a 4000K option for the kitchen as an option.These lights are in a different league compared to Suncos that have a CRI around 83-83 and give off a green/grayish cast to everything. Good color saturation and accuracy from lighting can really make a huge difference in the feel of a room.

These have a really night output level for the power rating. And by that, I mean a lot of the LED bulbs advertised as 65W equivalent only put out 650 lumen, where as these are 850. I don't have any way to measure the exact output, but they are noticeably brighter than a 650 lumen.The 3000k color temp is a perfect middle ground between the yellowish 2700k and the blueish 4000k.Most importantly, they handle a full range of dimming without any noise or flickering. I have 2 of these behind a Kasa Smart HS220 dimmer, and the other 3 behind a Kasa Smart KS230 3-way dimmer. All are working perfectly.

I am building a new house and wanted to pick a standard bulb with a consistent temperature. After testing several other brands, I determined this bulb fit my requirements. I am dimming with a Jasco Product Z-Wave + dimmer, and it performs flawlessly with no detectable flicker. I gave it five stars for longevity, but who knows? Check back with me in about 20 years.

These have the best light quality and color and of any LED bulbs I've ever used! I replace one of my old bulbs with one of these and noticed such a improvement that I swapped out the entire room! Things in the room look better and I feel more comfortable / peaceful.To explain several factors that make these bulbs great:Traditional incandescent bulbs have a "soft white" color (which has more yellow and less blue) and are rated at a "color temperature" of 2700K. As bulbs get more toward true white (sunlight), the number gets higher. You can even get LED bulbs that go as high as 5000-6000K. However, even though light similar to "true sunlight at noon" sounds like it would be good, it is best not to go with extreme whites at home, because humans are not supposed to use "blue light" or true white at night.I prefer bulbs rated at 3000K, because they are just a tiny bit less yellow than 2700K but still in the healthy range. So 3000K is the color of these "JandCase" bulbs that I've been buying. I bought 12 of these bulbs in Oct 2021, and 24 more in Nov 2023.But these bulbs are great for reasons beyond the "3000K" color they are available in. One of the MOST IMPORTANT things is the "CRI" or Color Rendering Index. The index goes up to 100, and 100 would be "100% accurate color rendering". The best light will make colors show up accurately. I always avoid bulbs if their CRI is less than 90. Many of the "good" bulbs will list "90+" (as do these) which is a helpful guideline but obviously it still leaves room for uncertainly.Why does CRI matter? Have you even lit a room with LED bulbs and then felt like "it's bright enough but I just don't feel like I'm seeing everything correctly? It feels like my eyes are weak or malfunctioning!" That's because some LEDs don't give enough of the true visible light spectrum to let you see every color accurately. If you used a prism to break down sun light into a color spectrum (rainbow), it would be a continuous range of every visible color. If you do this with light bulbs, there can be many large gaps in the spectrum. LEDs rarely generate the full spectrum, and often even less than old incandescent bulbs did. So the question becomes "how much of the spectrum is enough for things to look right?"I already had "90+" CRI bulbs that I was quite pleased with. However, the moment I replaced my other brand with one of these, I noticed an improvement.How bright (lumens) is also important. These bulbs are great by this standard also. They are labelled 850 lumens (which is pretty high) and seeing them in action convinces me of their brightness. (Not all brands seem to live up to their rating, but these do.)UPDATE: As of June 2024, three (out of my original 12) of my bulbs have stopped working (after about 2.7 years of use). This is a shorter lifespan than other LED bulbs I've bought.

So far these are great lights. Bright white and no yellow tinge. They also do not hum or buzz at all like some LED lights. They are bigger round at the ends (didn’t pay attention when ordering) but they fit perfectly into our cans.

I ordered a 6 pack after I moved into my new house last year. I've already had 3 of these bulbs burn out, after 6-18 months of use. These things should last for years in a normal household application, but the supplier cheaped out and made these with the absolute cheapest components.The lights look fine at first but don't last near as long as they should. Just creating more junk to fill our trash heaps!

I studied a lot bulbs before making my purchase. These bulbs are perfect for my kitchen canister pendants. They work with my old dimmer switches without a buzz. I'm very happy.

These live up to expectations. They use very little power generate almost no heat, and are way better than the incandescents they replaced. One did flicker a little at first, but that stopped after a few days.
