4000K is yellowish, but 5000K is like the natural sunlight. If you want the room to be like early morning, use one bulb. If you want it to be like mid morning, use 2 bulbs. If you want it to be like noon time, use three bulbs. You get the idea!

What a relief to have color that feels full!

I bought one bulb to try out in the 5000k range and was surprised at what a nice light it gives. I never liked the coolness of led’s; they felt harsh to my eyes and less natural. I’m now gearing up to order a linear tube, color correcting bulb for my art space. So glad this company makes high quality led lighting with a high CRI. I’ll surely be a repeat customer throughout the years..

I placed this thing in my dining room and bedroom and it lit up like I was outside. I take a lot of pictures of old photos, and getting the right color as the original is very important to me. These lights performed outstandingly in allowing me to achieve what I was looking for. The true colors of items in the area of use are now MUCH more realistic than ever. Thanks

Bulbs are great! No need to buy expensive new lighting for painting. I just used my old and replaced the bulbs. I wish I could buy in Canada.

I am an artist (painter) and so very careful with the lights I use in my studio. Couldn't be happier to have purchased these. Great in every aspects Waveform Lighting promises. Thanks

Just starting my printing and framing journey. After researching several lighting options, these bulbs came across as the most economical way to start. And they do not disappoint.

Being a standard E26 bulb I can place them in many different locations, situations, and setups to evaluate the future purchase of more expensive lighting options for displaying my work.

If you're new to art lighting, this is a perfect bulb with which to start. If you're experienced, this is a perfect bulb with which to experiment with "proper lighting" in different locations and situations.

I work in the Art Department for film & television and recently ordered two of these bulbs to help with colour matching. We often pick Pantone colours and match against our supplier's paint chips. They have been hugely helpful and have made a significant difference for myself and my team. I would fill our office with them if I could.

I have a mild case of deuteranomaly colourblindness and these help me to close the gap when dealing with nuanced colour differences.

These bulbs are bright without being harsh on the eyes. Great for illuminating surfaces when working day or night. Also excellent when taking photos of art work.

Purchased a 6500k bulb just to see what it was like. I am extremely satisfied with the bulb as well as the help I received from the company in determining my needs. I will be making additional purchases from the company in the near future.
