FAQ:

Q: What is bad about LED lights?

A: – Flickering LED lights – LED bulb on transformer flickers Quality of output voltage Minimum load – LED lights flicker on dimmer – LED lights sometimes flicker – LED lights flicker when switched on – LED lights flickering when switched off – LED lights flicker on motion detector – Conclusion

Q: Why do LED lights look blue?

A: Why do LED lights look blue? With today s technology, it is a pretty good guess that they look blue because they are meant to look blue. Quite often LED lights are manufactured to produce bright blue-white light, and in those cases, it is only natural that the light would tend to look bluish.

Q: Are LED light bulbs worth it?

A: TL;DR: Most of the time — Yes! Replace every non-LED lightbulb by an LED, with the exception of energy saving light bulbs. Most of the time, buying a more efficient LED which ues maybe 1W less is not worth it. In Germany, I would spend that much per LED:

Q: Do blue LED lights whiten teeth?

A: LED (light-emitting diode) produces blue light to increase the teeth whitening process without any radiating heat to the teeth. Most over-the-counter tooth whitening kits with lights contain LED products – although dentists might use LED blue light, as well.
