Very fine light for a vanity

I purchased this for the vanity in the main bathroom. It has three lights. I'd installed 2700K and 3000K since lower quality LED's looked better at those color temperatures. 5000K looked harshly blue. These don't appear harsh or blue at all. Skin tones look healthy whether white or black skin. This light also works well for artwork although the Waveform Absolute Series 99CRI Lightstrip is better. The difference matters for specific oil pigments. I may make a small strip light for the bathroom just to satisfy my curiosity but the difference between Waveform's LED's and other manufacturers is breathtaking enough that it may be a long time before the strip light project is realized. I have other places for the strip light first.

I use these bulbs in my office where I do print work. They provide the perfect environment to do such color critical work. I'll be buying again.

Northlux 95 CRI Bulbs

I recently bought several Northlux 95 cri bulbs from Waveform to use in drafting table lamps, and I have to say they work just as advertised. Both color temperature and luminosity are great and perfect for the copy and print work that I need to do in conjunction with my art practice. I just got them so I won't comment yet about durability, but right now I would not hesitate to order again when I need replacements in the future.

Convenient Quality.

These bulbs allow me to use the quality 95 CRI lighting in my standard bulb lighting gear. Love them!

Flicker-free light for the studio

These bulbs are truly flicker-free. There’s no invisible flicker to trigger my migraines. I couldn’t be happier about discovering Waveform. These are the perfect bulbs for the studio, especially if you want to avoid the health risks of invisible LED flicker.

While not specific to this product, I’ll add that Waveform’s customer service has been absolutely amazing helping me to understand the options for flicker-free industrial LED lighting. We need to fix the lighting in a workplace renovation because LED products made by other companies have invisible flicker that gives me headaches with debilitating “brain fog” that keeps me from doing my job. I am so grateful to Waveform for their product lines and outstanding customer service. They have given me hope that solutions are possible.

Every bulb burned out within 2 years - Important Update

I ordered a six pack of these back in Jan of 2019. Every last one burned out by the two-year mark. While they worked they looked very nice (which is the only reason this isn't a one star review), but the supposed benefit of LED longevity was way overhyped (and overpriced). My friend, who bought other bulbs from this same company has had similar problems, and when he tried to use the warranty this company gave him the run around, so I won't even bother. I'm going back to standard bulbs, at least then I'll get my moneys worth.


Josh from Waveform got ahold of me and confirmed that there was in fact a defect in the batch of bulbs I purchased. He offered to replace the bulbs in accordance with the 3-year warranty with no hassles. I am beyond impressed with both him in particular and Waveform in general, for the way they handled what could have easily been a bad situation. I also contacted my friend and got his situation straightened out too -- both of us are now very happy and will undoubtedly continue as customers of Waveform going forward. It is comforting to see a company that stands behinds it's products and takes the warranty seriously.

Hi Jason,

Thank you for reaching out and we sincerely apologize for the inconvenience and disappointment caused by the premature bulb failures. Our early batches of this product did indeed have some longevity issues, but these have been resolved with subsequent production batches (shipped mid-2019 onwards).

Please do know that your lamps are fully covered under our 3-year warranty, and I will be reaching out to provide free replacements for you immediately.

We're also sorry to hear about your friend's experience in processing a warranty claim. I'd like to follow up on this as well to ensure that your friend's replacement lamps are also taken care of.

So glad I found these

I have always been looking for the best lighting for art working and these are it! I got the regular style bulbs and they do the trick.

Hi fi lights

I’m a painter, and use these lights for maximum color rendition in my studio. I believe the are worth the price.

Comparing Northlux 5000K and 6500K bulbs with Cree 5000K bulb

I'm a painter, and have no affiliation with either company -- just interested in which bulb will work best for my painting studio and for photographing paintings and comparing scans with the originals.

Compared the Cree "Experience Exceptional" 60w equivalent 5000K bulb (TA19-08050MDFH25), with the Waveform Northlux 5000K bulb, for use in painting. My first impression was that the outer shell of the Waveform bulb seemed thinner, and had noticeable scratches and odd places on the surface. Nothing like that on the Cree bulbs. (Once I did get a Cree bulb with a slight scratch and Home Depot replaced it immediately.)

Then, although the labeled lumens on the two bulbs are close -- 800 lumens for the Waveform, 815 for the Cree -- the difference was immediately noticeable. At the same distance, my lux meter measured 722 lumens for the Waveform, 956 for the Cree.

I knew about other differences. The Cree bulbs are less expensive, dimmable, and carry a 10-year warranty (which I've used and has always been fulfilled). I was willing to overlook these differences, though, if I could see that the Waveform bulbs did show color more accurately, and if the 6500K bulb would be valuable for checking paintings, in case a collector or gallery displayed my paintings in that cool a daylight.

So, on to the color comparisons. This was made difficult by the difference in brightness. This seemed to make more difference, to my eyes, than the CRI of the bulbs. The stated CRI for the Waveform is of course 95, and for the Cree just 90+. When this particular series of Cree bulbs was introduced, I talked with a technical expert at Cree about the CRI. He said their tests show that it's quite a bit higher than 90, but they prefer to understate it.

Looked at my paint swatches under both lights at different distances. Keep in mind that I'm only using my eyes here, not a spectrometer or any other special tool. I did recently take the hue test, and came out with a perfect score, so my vision seems to be reasonably trustworthy. Having studied the Waveform technical information, I paid special attention to the reds -- also to see if blues and yellows looked warmer or cooler under the two lights. I just couldn't find a difference.

So the other question was, would it be worth at least buying the Waveform 6500K bulbs, since Cree doesn't make bulbs with a Kelvin rating that high. I don't enjoy 6500K lighting, but if it made a difference in color values or anything else that would make my paintings look wrong if hung in mainly north light, it would be worth using the bulbs to check that, just as I'd want to check a painting under 3000K halogen light (since many collectors and galleries use that).

The 6500K bulb seemed a lot bluer than the daylight -- at least by judging a whiteboard under it in lighting from different directions. And the paint swatches looked fine in that light, no matter how I arranged them. So I decided not to get even the 6500K bulbs. I'll keep them in mind if I do decide later that it matters.
