Awww mugs got butthurt for mother Gaia.
It really is his loss though. I've tried to completely move away from incandescent bulbs, more for the power savings and cost more than anything. CFLs I once used, but discovered they just aren't as good for the typical household usage scenario, especially for those cost-conscious homeowners who turn off lights when done and tend to turn lights on/off a lot throughout the day.
It helps to be a little more green, but for many, saving on the power bill is a big win alone.
What also helps about LED, those Cree bulbs so far seem fantastic (Cree LEDs ARE fantastic; they being in a consumer product, and affordable, is new) and are super cheap for the technology. We'll see just how good the warranty department is, but these things have a 10yr warranty.
Most importantly, it's all that (dimmable, long-lasting, strong warranty), they are around only $10-$15 depending on specific bulb.
Something that I personally just discovered, right this moment: they also offer higher-CRI bulbs. That's been the largest failing of all types of light that are, well, not standard incandescent. One of the worst offenders in CRI is Sodium Vapor (the green/orange-ish streetlights) you know, the ones that make the area look really weird, muted? That's the low CRI effect, and demonstrates what the spectral limits of different types of light allows our eyes to see in the visual spectrum. True outside daylight is 100 on the range, and most good incandescent bulbs are pretty much right there. Most CFLs barely make 80. If it's not energy star rated, it's probably much less (Energy Star requires, other than a specific electrical usage, any Energy Star certified bulb of any lighting type to also have a CRI of 80, another thing I just learned ). A CRI of 80 is generally "good enough" for the regular household use, but, not good enough for color critical viewing. It's not really helpful in the kitchen, that's for sure. And gallery or photo studio lighting should be high CRI for accuracy (especially in areas working on the digital imagery production - like where you edit your digital photos).
I've just learned that Cree also offers a "TW" series bulb that has a 93 CRI. I'm actually planning on buying these now that I know, lol. Sadly, they aren't available in the Daylight temperature, only the soft-white in 40w and 60w. They also have 75w soft white, but not a TW variant. I think the basic models, the ones I currently own, are mid 80s if I recall what I read awhile ago. They do look better than the CFLs I have owned in the past (the color/appearance of colors throughout the room, the actual color temperature of the light, etc).
I've had a couple Philips warm-white LEDs before, and they worked great (put in kitchen fixtures to replace some CFLs), but they were more expensive than these Cree bulbs by far. I've switched to them completely - that warranty is very attractive. You'd be hard pressed to spend less in any bulb variant when you factor in energy cost as well. Incandescent was cheap, but the difference is in the electric bill, and then some.
