I am excited about LED lights for their efficiency, but keep seeing articles like this and don't understand the practical ramifications, like "what bulbs should I buy?"
I messaged Cree on Twitter, expecting a very corporate response, but they linked to some studies (which I haven't yet had time to explore.) FWIW - https://www.energy.gov/eere/ssl/street-lighting-blue-light-and-light-night https://www.energy.gov/eere/ssl/street-lighting-blue-light-a... and https://www.lrc.rpi.edu/resources/newsroom/pr_story.asp?id=378#.WjLMBFWnGM9 https://www.lrc.rpi.edu/resources/newsroom/pr_story.asp?id=3... were the resources they suggested.
- herf 8y agoThe message is: there is no more risk from LED than older sources, by the metrics we have now. I would suggest that one problem is that LEDs don't "warm dim" (unless you get some special ones from Philips and a few others), and people tend to dim them less overall.
- nathan_long 8y agoWhat do you mean by "warm dim"?
- herf 8y agoAn incandescent/halogen will go to warmer temperatures when dimmed. So it might start at 2800-3000K but be 2100-2200K at 1% brightness.
