I've had this light for a year and a half now, in a floor lamp connected to an in-line dimmer. Ideally I would be using an A21 in such a lamp, but Waveform doesn't make one that's dimmable in 4000K. 4000K, I could spend hours talking about this color temperature and very few companies offer 4000K, let alone 4000K in high or ultra high CRI. Not too warm, not too cool and that 95+ CRI really makes colors feel alive, especially reds, something that the majority of LED bulbs fall flat of doing. The in-line dimmer works pretty good for the most part, some positions on the slider may cause the bulb to flicker, but a little tweaking of the switch solves that. I highly recommend this bulb!

I love Waveform's website. There is so much information there. I've really gotten an education about light in general and lighting in particular. The BR30 4000K high CRI bulbs are wonderful in the interior rooms of my condo that receive little to no natural light. I look forward to gradually updating all the lights in my home with Waveform's Full Spectrum, High CRI bulbs. Also, shipping was efficient, and customer service response is excellent.

replaced older bulbs with the full spectrum - Oh my gosh, the difference!! Did one to see if I liked, then you see the difference in the light given off old bulbs (yellow!). Have 6 in kitchen now. We will be going each room.

Very bright. Plants around them growing nicely! And my SAD is under control!

Got the 4000K for recessed lights in bathrooms. The light is wonderful and the bulbs dim perfectly.

I bought 6 of these for my office 1 year ago and 2 have failed.

GIving 3 stars because the light quality is good and Waveform has been good about replacing.

We use these bulbs in track lights mounted high up on the wall ... overhead is supposed to be the optimal position for Seasonal Affective Disorder therapy, but also, it seems to extend the daylight hours in the house after the dark season shortens the day.

Works perfectly - noticeably improved color fidelity next to off the shelf BR30 LEDs. I'll buy more.

I have been buying these bulbs from Waveform for my art studio for the past 2 years. My favourites are a combination between the 4000K and 5000K. I am super picky about my colors so these bulbs have taken out the paranoia for me in the art studio! Life savers. Also Caleb in customer services has always been very helpful.

I compared these bulbs to several other high CRI LED bulbs and the quality of the Waveform light is superior. Hard to explain, but it's a very balanced, pleasant light. We've had issues with a couple of the lights (out of 40+) blowing out prematurely, but customer service has been prompt in sending replacements at no charge. Overall we're very pleased with our purchase and would recommend Waveform lighting.
