I just wanted to make sure I'm using the right rating on my resistors that will be used inline with Athearn Genesis mini-bulbs (as found in their F units). I have calculated that the minimum I should use is 680 ohms, but is there a lower rating that would result in brighter bulbs, without severely shortening their lifespan?
Also, I've read that mini-bulbs don't handle special effects well (gyralights, etc.). Is my memory correct here? I have an F unit with 2 bulbs per lamp, and one of the lamps is supposed to be a vertical gyralight. If both bulbs were programmed as gyralights, would this make a decent looking emulation, or is it not worth the time? (I'm accustomed to replacing these bulbs with DCC compatibles, but want to try resistance for a change...)
