I've made multiple purchases from Waveform Lighting. My most recent is the B30 LED full spectrum bulb. I'm using the 5000K bulb for proofing photographic artwork, and the bulb lighting is beautiful. I have a spectrometer, and the light is indeed full spectrum at approximately 5000K as advertised. I've tried other brands of so called 5000K daylight lamps, and determined they were not full spectrum. That's what led me to Waveform Lighting. I would also add that customer service is excellent. They respond to my questions quickly and pleasantly.

I purchased a dozen high CRI lamps from a number of manufacturers. This one was the best at revealing every color in every artwork, photo, plant, and even a random gray cat. It seemed better than a couple CRI 96 and 97 lamps. It did not seem to trend excessively blue like some 4000K lamps.

It's effective at combatting Seattle winter overcast and 16 hour winter nights.

i originally bought these lights for a track extension They changed the room

I then bought and redid my entire track system with them.

They make such a difference in December in Manhattan

Light is primo and these are fabulous for artwork and for general use

The bulbs are, by far, the closet to halogen or incandescent lighting I have used. I will use these ultra high CRI bulbs from now on in my home. Great product and well worth the cost!

I got this bulb because I was tired of low CRI LEDs that blinked like crazy and made my dog restless. I have used a Sekonic C-800U to measure the spectrum response and found it to be 99+. That is almost as good as incandescent bulbs. I like the much cooler tone compared to incandescent bulbs (4000K). I am planning to replace all the LEDs I have with Waveform lighting bulbs.

I’ve juggled light bulbs for over a month looking for clarity and pure color for my art and home decor. Everything seemed to still have a yellow tone, going to higher kelvins gave a blue tone. This bulb is great! It’s enough kelvins to get out of the yellow and not in the blue! Add the high CRI and they are perfect!

I bought these for my “dog room” to be sure to provide daylight for my dogs while I’m at work.

I ordered 1 qty of BR30 4000K bulb to try out first before ordering more for my project. The light output seems OK as described. However the bulb arrived packaged poorly in plain white box inside an envelope via USPS. The bulb itself didn’t look new having some scuff marks and visible black spot on inside of its body. This was enough to convince me not to buy more of this for my project. I will keep the bulb and not go through the hassle of returning it.
