Searching for reliable 4000K lightbulb that doesn't buzz.

Have any decent, budget friendly 4000K light bulbs come on the market yet that are fairly priced, reliable and don't buzz?

You can refer to this, at lease for the light quality perspective. Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest

I think you might need to specify the shape and socket so people can better help you.

I have these Hyperikon, they are great.
4000k, 93 CRI, and no buzz, dimmable, instant on, good price.

Thanks Joshk, I was looking at those yesterday as the 4000K ones weren't on the amazon Canada site. Is the 4000K tint pretty good? Just don't want the harder bluish or greener tints of the 5000k up.

I’ve got the 2700, 3000, 4000, and 5000. My favorite is the 2700 simply because I have a mix of LED, halogen, and incandescent in my house, and the 2700 is the match for the rest. The other 3 temps look odd when they are turned on at the same time as halogen/incandescent just because they are different.
During the day the 2700 color is mixed with sunlight through the windows anyway, resulting in an effective color closer to 4000k.

Looks like you have a lot of lights in your house! Halogen is still my favourite but my wife wants the 4000k for the kitchen so I just ordered the ones you suggested from your link and see how she likes it, thanks.

Sounds good. Report back how you like them.

The bulbs finally arrived today. They seem to be 4K as they are yellower than a 5K bulb and not so yellow as a 3K bulb but they have a depressing feel about them. Hard to explain, but to compare, I have a 4K work light and the tint is just beautiful and pure.

What color are your walls?

All white walls.

Yea, they are terrible bulbs.

jk :innocent:
I went and did a Spectrometer test just now for you on a Hyperikon 2700k I bought on Amazon July17, this year. The results are below. It shows it exceeds the CRI promise at 93.4% and if anything it is a bit weak on the yellow area. The tint is almost sheer perfection too.

Haha, you got me there! Well, at least we know now they make good 2700K bulbs. Just for reference, my work light is 4000K and 5000 lumens and these Hyperikon lights are rated at 840 lumens each. I have six of them in the kitchen so 6 x 840 = 5040 lumens. The thing is, my 5000 lumen 4000k work light lights up the room to almost twice the brightness so something is off somewhere. I know I can't really do a direct comparison, but if I had to guess, these lights are about 500 lumens each max.

haha
But I see now should have measured a 4000k for you. Maybe I have some data on my PC about them…. brb

If you have anything that would be nice thanks. I'm wrong about 500 lumens for my guestimate as I switched one bulb with a 450 lumen 2700k bulb and the hyperikons are for sure brighter so just my eyes I guess. It's not going to be scientific but I'll wait for nightfall and see if everything changes and things all of a sudden look much better.

Our brains can tell us the light is wrong if it’s different than our memories, maybe you will adjust in a few days. idk

Very possible since the kitchen was lit up with the 5000K bulbs for so long that maybe we just don't get it yet. Still doesn't explain how beautiful the work light led is when comparing 4000K lights.

Found the data on my 4000k hyperikons
The CRI of 93.1% matches the advertised 93%. The yellow seems about right, but the green is a bit strong, causing a positive Duv (aka tint). Can I interest you in a can of Green Delete? :innocent:

I think you found the problem that we are seeing in that the green is overwhelming the purity of the light. Nothing like a detailed chart to confirm this thanks. Couldn't put into words what was off but it is the overbearing green that is doing it. Oh well, I'll keep searching for a decent 4K light and hopefully find it one of these days. BTW where do you find these charts?

My wife is using the 5 in the dining room right now with little else on in the house. The spectrometer confirms a tint in that room, but neither of us notice a tint at all. It must be that we are used to it.
