Hello ALL:
A fellow modeler and I were talking about white LED's a few days ago. He asked me why people are putting white L.E.D.'s into thier locomotives?
I said because they last longer and brighter. He braught it to my attention that it's not phototypical correct. He asked me, "Have you ever seen a super bright, white light coming from a locomotive? Specially steam?" I said no.
His point was that everyone was jumping to use LED's, but shouldn't. He prefers to use a wheat stone bulb that is dimmed. He loves his steam in N scale. The main headlight should not be an LED. It's ok to use LED's as marker lights on your passenger cars and cabooses. We even reconmend that you do.
How do they make a white LED white? The main LED is blue. Then they add a red and yellow phosphorus. When the blue light hits the phosphorus, it makes white light!
Look very carefully if you have one of these turned on. Do you see a blue tint?
Andy
