Saving energy through LEDs
Hello,

to steer the discussion into a more fruitful direction, we should note down, that by replacing incandescent bulbs with LEDs, energy is saved if and only if:

You have it in a place, where only light, but not heat is needed, which means:

1. All outdoor lighting
2. Indoor lighting at elevated outside temperatures

Additionally, the higher lifespan of LED's , which is up to 60-fold that of an incandescent lamp, reduces litter and saves time and effort to replace it as well as it eliminates downtimes without light.
Furthermore the more evenly distributed wavelength spectrum of LEDs is not so depressing (in my opinion) than high red wavelength fraction light of incandescents.
