Cree Lighting A19 LED Bulb 75W Equivalent - 1100 Lumens, Dimmable, Soft White 2700K, 25,000 Hour Lifespan, 90+ CRI - 24-Pack - Perfect for Bedrooms, Living Rooms, and Enclosed Fixtures

By my estimation, this bulb ran around 6000 hours (2 years, 8-10 hours a day). Bulb failed after 2 years - wouldn't produce light. A tear down revealed a failed component, interestingly not the LEDs or capacitor. While I believe the bulb is well designed, I would hope this specific issue has been resolved since I purchased the bulb.For those interested, the failed component was a filter inductor, L1 on the internal PCB. It failed open and being in series with the incoming power, prevented it from reaching the rest of the circuit. This is a wound component, consisting of many turns of fine wire on a ferrite core. Notably, this one was dipped in heavy epoxy (not the typical magnetic component varnish used on coils and transformers). While I couldn't determine where the wire broke, a teardown of the coil revealed signs of overheating. My theory is that by dipping the coil in the heavy epoxy/potting compound increased the temperature rise within the coil (as the fine wire is also resistive and the coil will heat up while in operation) which led to some type of a stress failure of the wire (not burning but essentially stretching open). Other LED fixtures use similar components - I've never seen one dipped in a similar manner.I was looking for something with more light than the 60 watt equivalent and prefer the bright white over the soft white + was dimmable. For those features, these 75 W Cree bulbs were great. What I do not like is that of the 6 bulbs I originally purchased, one failed within a few weeks and two others failed at about a year. This is not an inexpensive bulb. A fifty percent failure rate in one year for a bulb that lists a 22 year lifespan is unacceptable. After the first bulb failed within the first month, well, it happens and two more were purchased so I would have a spare. When two more bulbs failed within a week of one another at about the one year mark, I am questioning if I should cut my losses and find another brand.Update - I contacted Cree online to submit a warranty claim and entered the information printed on the bulbs. Within a few days, Cree replied and has shipped replacement bulbs. Adding one star back for ease of warranty claim and timely response.The light output of this 75W bulb matches about the output of a halogen 60W bulb. I use halogens and LEDs in the same room, and there is truly no color temperature difference. Color rendering, as for all Cree bulbs, is very good. The only drawback is they hum noticeably with a supported Lutron Caseta dimmer. It is not terribly annoying but noticeable in a quiet room. To note is, that this bulb is hard to find and appears to be identical to Cree's Pro Series A19-75W-P1-30K-E26-U1 bulb, which appears to be easier to find at supply houses. I bought both and compared them side-by-side.After trying and returning three other LED lightbulbs, I'm glad I bought these. The 3-bulb light fixture in our tiny half bathroom is clear glass and the bulbs face downwards. I had 40 watt equivalent LEDs in there as the light is otherwise harshly shining in your face, but the entire tiny room was too dark. These bulbs are soft and warm while plenty bright to light up that roomI bought several of the 5000K bulbs to brighten up the basement. The moment I powered them on they emitted an immediate audible buzzing. I varied the dimmer, but not matter what brightness setting I changed it to the buzzing persisted. That's unfortunate because I love the light and color, but I do audio recording in here and the mics pick up the buzzing very easily. It's also loud enough that I just can't ignore it even if I tried.We replaced another brand of LED in our 3-bulb dimming kitchen fixture. With the old bulbs, one was almost always going out, and had to be tightened or replaced. And the bulbs never really dimmed that much. It was more a matter of on, low, or off. When we had an electrician over for another matter in our kitchen, we asked him to check our fixtures, thinking that was the problem. He tested it and said the problem was the brand of LED. He only uses CREE. We ordered them, put them in, and there was a world of difference. The color was better, the bulbs dimmed all the way, and all three bulbs worked consistently!I bought these for my art. Perfect for color mixing. Good value for the money and plenty bright.I picked this bulb due to the right lumens range and the CRI. It is described on the box as both soft white and bright white.My mistake was in not checking the color temperature. Unfortunately I had assumed that with a high CRI it would work well in a color matching environment. Not so. Turns out that CRI only measures how well the light source mimics a blackbody radiator at the same color temperature. So if you are matching color samples or paint or working with photographic prints find a daylight spectrum (5000k+) lamp.
