I'm a photographer and I have a Fine Art prints laboratory. These lights are absolutely perfect for the quality print check and the whole illumination of the studio.
I bought two bulbs and they work great. After a year, one of them started flickering and I contacted customer service and they had one shipped out the next day free of charge.
When setting up a home office I searched high and low for a great light source that could generate light close to daylight and keep me motivated even on the gray days outside. I tried a few different bulbs and finally found Waveform's color matching bulbs. The high CRI is very good. When compared with another daylight bulb in the same room, the Waveform bulb has the deeper reds where the other bulb is clearly harsher blue in spectrum. It blends well with the natural sunlight on sunny days. Very happy with the purchase and look forward to buying more.
In the past when printing art reproductions I've had to go on faith that my lighting was good enough. With these bulbs I know I'm getting a clear look at the art, the prints, and how they compare. It makes the process faster and easier without having to second guess myself!
Replaced the lighting at all the stations. What a difference! Now the students can really see the colors they create. Thanks Waveform!
I'll never use another light bulb for painting: I use them night and day with confidence in color matching. The LED bulbs also emit low heat when using which really helps in the summer. Also the bulbs are light-weight which makes them easy to use in any fixture--especially clamp-on. Recommend without reservation!
I work in the magazine industry as an image retoucher and it is critical to work within a color calibrated environment with the type of work I do. Viewing printed proofs under these lights while working remotely from home match the light booths that I am normally used to work in at the office perfectly.
My career has been in the printing industry as well as the photography/ graphic arts industry. I am retired now and do photo editing/restoration of photos. I know the importance of color matching.
The Waveform Lighting's D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) was a very economical way of having correct lighting for color matching.
Over the years I've used the Kodak color viewing light selector to verify lighting conditions and print shops and photo booths. When I got the lightbulb I tested it and here's the proof that it works great. Shown below are two samples one with Waveform bulb the other with regular home lighting.
I don't think there is a better economical way of having the correct lighting.
I'm using the D50 5000K bulbs for scanning art. First pieces processed seemed to require less PS color correction. Looking forward to more consistent files for printing.
