- hnick 7y agoI didn't know that! Maybe that's why it's so annoying. My reference to blue was the common belief (fact?) that blue light messes with wakefulness hormones and isn't a good idea around bedtime (hence f.lux).
- londons_explore 7y agoNotably, while green LED's exist, we haven't yet managed to make an efficient green LED. If we had, then illuminating streets etc. with green LED's would save a lot of electricity for the same perceived brightness.
- eveningcoffee 7y agoIt is good then that we have not. Green light is the most ugliest kind in my opinion.
- londons_explore 7y agoA lumen is already a measure of perceived brightness. You can have a 10 watt UV light, but you can't have a 10 lumen UV light for example.
- knodi123 7y agooops, I meant radiant flux instead of lumens.
