Maybe there are situaties where we could choose to have yellow light instead of white light. Or indeed: green light. | |

| Jun 7, 2013 at 23:16 | comment | added | Nate | Understood. It's a great question, I just wanted to address part of it, by saying that I do think "standard LEDs" have sustainability benefits. I'll see if I can dig up some more, but hopefully someone else can also chime in and answer your concern more directly. | |
| Jun 7, 2013 at 23:10 | comment | added | Evan Johnson | This is a good answer, and your points about rare earth supplies, recycling, and the long term are excellent. However, I would still like some information not just on LEDs vs other lamps but also on LED A vs LED B if it is available. | |
