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

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.

Now that I know my dining room bulbs have room for improvement I’m going to paint them with Green Delete tomorrow. I’m looking forward to checking out the results tomorrow night after dark.

Have you looked at Waveform Lighting? These are pretty terrific bulbs. I use them all over my house and they are actually CRI 95+ according to my Sekonic C800 with kick ass R9

I never knew one could do something like that, I'd be interested in your feedback.

Very tempted to try them. This time I'll just buy one of them and see how they compare to the others, thanks! With shipping and our forever low Canadian dollar it's probably going to cost me $30 a piece, but I can live with that if they are really nice to the eye.

I think the 6 pack is quite a bit cheaper. Also, they have a no question asked return policy. If you do not like their stuff, they will even pay return shipping for the bulbs.

And it’s dark. That’s some good looking white light. I can’t say I feel it was tinted before, but it feels perfect now.

So how did you do it? If I can reduce the green then it would be just perfect.

I spray painted each bulb with Green Delete spray paint. It’s a paint I started making last year and talked about here . One coat of Green Delete makes bulbs and lenses rosier by 0.002 Duv.
User lukehale asked me to make him a can a few weeks ago, and in the PM’s we’ve been having he says he is quite impressed with the stuff too.

Thanks for the link. Will read that thread tonight and see if it is something I want to try!

A can weighs 1 pound, so more than a light bulb. International shipping probably isn’t cheap.

I may try that one day not so sure yet. My wife is starting to warm up to the new bulbs but I'm not really at the moment.

It’s been 2 weeks, what’s your opinion of the tint now, @klrman?

I honestly don't like it, but it grew on my wife so much that she doesn't want me to mess with it anymore so my hands are tied! Since we've had it for awhile I don't even think it's the slight lean towards greenish that is bothering me. For some reason my eyes feel strained with them, they seem to do something weird to my eyes. She loves it though as I don't hang around the kitchen anymore when she's cooking haha.

Maybe they just need a dimmer? idk
Thanks for the update.

That may help me, but she likes that it's so bright as all 6 bulbs are on at the same time. Thanks for suggesting them to me still as she really loves the tint now,
