Customer Service

Customer service is great. Very responsive and expedient.

Its Daytime Again!

The full spectrum 6500k bulbs do a great job of reproducing a daylight effect in a room with windows on cloudy days.

Did not work with magnetic ballast fixture.

I have several Waveform medium screw base bulbs and I really like their color output. So I ordered the Waveform Full Spectrum T8 LED tubes. They did not work in my lighting fixture which has a magnetic ballast. I live in an apartment, so I could not change out the fixture or rewire it to bypass the ballast. Waveform accepted my return with no problem.

Great lights

These are great lights. I got them to replace existing fluorescent tubes.
I had some difficulties installing the lights, they only worked in one specific order and orientation. It took a while to go through all the permutations. I did not bypass the existing ballast, simply tried the lights.
Once installed, the lights work great.

Great tubes

I bought 4x of these high-CRI, 4000K T8 LED 4ft tubes for a photography application and was very happy with the color. The price is astronomical, so I can't afford to do the whole house, though. Unfortunately, 2 of the bulbs didn't work on receipt (sounded like something was loose/broken inside them), so I contacted Waveform and they immediately sent me two replacements, which did work. I'm building some custom light fixtures for them now.
