One of my first NDG7475 520nm. This started happening a while ago but I ignored it. Whenever I turn it sideways, it does this and the brightness drastically decreases. This is without any lens on top. Is this inside the diode or what?
They have to. You need humans to physically separate and single out the difference between certain similar words. This will lead to a much better product. I don't really care at all but some people don't like that.
I would like to build or acquire something that would reach and be seen from very far away.
Similar to those concert lights:
I don't mind paying that price for it buuuuuut maybe I could build something more effective. A dozen...
