Now what I want to see with LEDs is more offerings in the "equivalent to 100 Watts" category (which would actually draw, what, maybe 10 Watts?). I like to be able to see around a room and read things without straining my eyes when I turn the lights on. ;-) | |

I guess I was being a little geeky. LED's for lighting have come a long way and they're finally getting over the final hurdle, which is price. There's just no way $47 light bulbs make sense. But now that they're getting down into the $10 range they're making a lot more sense, and between chemical doping and colored filters, the color temperature is finally into a range that humans can bear for long periods of time. I LIKE LEDs. Honest. | |

If you look at commercial-available LED bulbs today the CRIs tend to be higher than CFLs, and certainly the best LEDs are higher than the best CFLs. Both LEDs and CFLs come in a range of color temperatures, so that's pretty much up to the buyer to choose. I think it's a mistake to conflate color temperature with CRI. | |

But newer ones do have filters and/or colored bulbs that soften the light up and make it warmer in hue. Something to be aware of and check specifically when you're buying LED lights, though. | |
