The Cree 100W Replacement LED is a bigger, brighter version of, a highly acclaimed 60W replacement that made its debut back at the start of 2013. With the 100W version, Cree looks to be following the same formula: familiar-looking light, an industry-leading 10-year warranty, and an appealing price point.
Specifically, that price sits just a few cents below $20, which is certainly enticing when you consider that 100W replacement LEDs were selling for $50 or more just a few years ago. That said, Cree isn't the only LED maker that's recently taken big steps forward. For example,costs just a dollar more, and offers that same decade-long warranty along with a more efficient build. Cree's 100W Replacement LED is an excellent bulb -- but it's not your only legitimate option in this class. Put it at the top of your list it if you use dimmer switches, or might need to use it outside, but don't rule out GE, especially if efficiency is your top priority.
Cree's 100W LED looks a lot like the 40W and 60W replacements that came before it, albeit with a bigger bulb and a larger collar of heat sinks around the neck. This gives it some extra bulk compared to competitors like GE's 100W replacement -- that bulb has elongated, fin-like heat sinks, which makes for a narrower design.
Extra girth aside, Cree's LED is still a relative lightweight, weighing less than 6 ounces. The, for instance, weighs more than twice as much.
Cree's LED puts out 1,600 lumens from a power draw of 18 watts. That's very good, putting its efficiency just shy of 90 lumens per watt. Still, both GE and Utilitech do even better, with designs that put out 100 lumens per watt.
As for color temperature, Cree's bulb aims for the same, yellow-toned 2,700 K as most of the competition. If you want something hotter and whiter, Cree offers a 5,000 K version of the bulb for a dollar more. That's a nice option you won't find with every brand.

Like most LEDs, Cree claims that its bulb will last 25,000 hours -- well over 20 years if used for an average of three hours per day. Couple that with the 10-year warranty and the fact that the bulb will only add a little over $2 per year to your energy bill, and the long term value starts looking awfully good.
The color rendering score of 80, on the other hand, is a little less impressive. 80 isn't a bad score per se, but it isn't a standout, either. We've seen affordable competitors from brands such asand even score several points higher, making for a noticeable uptick in accurate color quality.
Outside of the 100W class, we've seen bulbs push that CRI score up even higher.does even better, scoring up into the 90s, as does and other bulbs from the GE Reveal line. Moving forward, it'll be interesting to see if any of the major manufacturers decide to release a 100W equivalent with those sorts of color-rendering specs, as there definitely seems to be room for such a product.
