Cree 9.5-Watt (60W) "2-Pack" Soft/Warm White (2700K) LED Light Bulb

As of 2024, I believe these bulbs are new-old-stock - and they’re (in my experience) far superior to newer more cheaply produced Cree (and other brands) bulbs.First, longevity on these bulbs really does run 10 years or longer as I have yet to have one completely fail. Of the two dozen I’ve bought over the years, I’ve had just one dim due to a few failed LEDs, but not go outright dark. I think this is largely due to the earlier (somewhat less efficient) technology using a larger array of LEDs with a heavier duty transformer and heatsink. Additionally, I think the LEDs are arranged in parallel series, so one LED failing open doesn’t take out the whole bulb. This is probably due to the comparatively high price of these bulbs during their production-run when LED lighting was new - back then they were still competing with incandescent and CFL bulbs. Today’s purposefully single point of failure LED arrangements are designed with “planned obsolescence” in mind, whereas these bulbs were about proving LED lighting reliability claims.The second interesting aspect of these bulbs is they exhibit measurably better color rendering beyond just what the CRI value indicates (which at 85 is numerically higher than the average soft-white bulb, which is usually 80). But even with the higher number, the actual color spectrum output is better tuned for “soft-white” than what that number might appear to indicate. Specifically, when analyzing the wavelength distribution (and, yes I measured the bulb versus common competitors with my own equipment), these Cree bulbs output a significant amount of longer wavelength (yellow-red) light, but also with a reasonable portion of blue light, while minimizing green values. This is in stark contrast to a typical modern “soft-white” bulb, which tends to output a lot of light in green wavelengths, with nearly all shorter wavelengths filtered out by the diode cap. The result is that sepia tone “washed out” effect where colors dependent on blue (470nm) through violet (400nm) wavelengths are just “lost”. Paintings and photos look nearly monochromatic under such light. In contrast, these Cree bulbs don’t exhibit that issue, producing a visible result that is very close to an old-school incandescent bulb. I suspect that they’re accomplishing this by having a subset of the LEDs pass more blue light (much the way RGB LED bulbs mix their way to a soft-white output).TL;DR - they produce light that handily beats many of the current batch of “best in class” bulbs from Philips and others, and they’re simply more resilient than “modern” bulbs.

I bought these to replace some 60W incandescent bulbs and they are fantastic.PROS:* First, they are significantly brighter than the 60W (855 Lumen) incandescents they replaced. Also seem brighter than the old 13W (900 Lumen) CFL I used in testing.* They use a heck of a lot less electricity than incandescents.* They should last for years and years.* These are hooked directly to a light switch (non-dimmable) and they don't produce any whine or buzzing sound, even with my ear directly against the bulb.* They turn on instantly. Absolutely no delay. I was a bit concerned about this, as I've seen other bulbs (CFLs in particular) that flicker on or take a second to 'warm up'.CONS:* The glass is coated in a shatter-proof rubber that is almost 'sticky' feeling. It clings to dust very badly... probably not good if your fixture is facing up.* They don't warm up my bathroom like my incandescents?OTHER THOUGHTS:* The color is slightly less yellow than the incandescents and CFLs I have, but for me that is fine.* They DO have a dark spot on the tip of the bulb, but it isn't noticeable unless I stare at the bulb.BOTTOM LINE:This is my first experience with LED bulbs and it is a fantastic one. The bulbs are a perfect replacement for incandescents and should save you some serious cash in the long run, if they can last 10+ years.

My outdoor lighting around my home is in roof eave soffits that are about 12 feet above ground and I was constantly having to replace the incandescent lamps due to them burning out frequently and having to lug out a ladder and climb up and change them. Additionally some times, I would forget to turn them off in the morning burning electricity that was wasteful. To counter this problem, I originally replaced my outdoor soffit lamps with CFL lamps but found that caused them to strobe and fail while using the photocell Thomas & Betts HS300D Dusk to Dawn Light Socket because the ad did not state that this photocell will only work on incandescent lamps. Next I purchased these Cree 9.5 Watt lamps and the Westek SLC5BCB photocell socket and they performed flawlessly. I was so pleased with these that next I replaced the CFL lights in my hallway and over the vanity in my guest bathroom because they took so long to get bright. The features that I like about these lamps are the color, brightness and instant on performance and the 22 year life. These are very close to the color rendition of the old incandescent lamps.

I purchased these two bulbs about a month ago and used one to replace a CFL bulb I had in an Ikea table lamp. It looked and worked great, until today. It just won't turn on. I tried it in several other lamps/outlets, but nothing. I might have just gotten the short end, statistically. I'll use the other bulb, and seeing how long that lasts (in conjunction with getting the suddenly non-working bulb replaced/returned) I may revisit this review. At this point, buy at your own risk!UPDATE: It's been a while since I left this review, but Cree did replace my bulb with a working one. It took several weeks, but the replacement bulb has been working wonderfully for the past several months.

Bulbs for my bathroom. Lower wattage then regular bulbs. Thanks

Cannot tell, this review is not final, I am going to just post this for now and wait until I get a replacement until I post an actual review.
