Replaced the lighting at all the stations. What a difference! Now the students can really see the colors they create. Thanks Waveform!

Rochelle Phister

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!

Excellent Product

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.

A must have tool for photo editing

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.

Improved Light Source

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.

Wonderful hight CRI light bulbs

Painting with watercolors at night was a challenge for me until I found waveform lighting light bulbs. The colors look very accurate and vivid. They've mentioned the CRI R9 in their website and I believe it is true. Red objects look more vibrant.

Great bulb!

I bought the D50 5000K A19 LED Bulb(ISO3664:2000) bulbs for color management, too.
There are no replacementable bulb in Koea. So order it from here.
I'll buy it again.

Highly recommended for individual photographers!

I bought the D50 5000K A19 LED Bulb(ISO3664:2000) bulbs for color management.
One D50 bulb is used as an ambient light source to illuminate the Photoshop/Lightroom workroom, and the other is used to evaluate digital prints.

I also have some D50 lights made by other companies, but Waveform Lighting lights are much cheaper and also offer very good light quality.
In addition, it can be easily installed.
I highly recommend the D50 bulb for color management to individual photographers.

Colors the way I need to see it

Needed a light for comparing and mixing colors. This bulb is bright and shows colors more accurately than the standard bulb.

Got them to put above my station at the tattoo shop. They are great and we are going to put them in the rest of the shop.
