I had an issue with a few bulbs damaged in shipping and the customer service couldn't have been better. They sent out replacements, I didn't need to send the damaged ones back, and they even threw in an additional bulb for good measure.
Eventually we will have 12 T8HO grow LEDS replace 20 fluorescent bulbs that put off a very unsightly purple tinge. Because Waveform's grow lights put out such natural, high CRI 98 color, it seems brighter already in the plant room with only four T8HO LEDs currently installed than it did with 20 fluorescents of the same length.
My only complaint is that the bulbs are so popular they seem always to be sold out!'
I'm so pleased I'm going to order some of their flicker-free indoor lighting bulbs today.
