LED conversion

(1/1)

jennifer:

           Thinking about swaping the 44s for LEDs on project Galaxy.... since this would be my first convert any advise would be helpful.

Jeff AMN:
When I do conversions I only do the inserts. For GI, the game looks best with the incandescent bulbs. With LEDs, those inserts really pop and they're amazing in a dark room.

jennifer:

         Do you use the colored ones under corresponding colored inserts. i.e red under red, green under green, or do you just use the white?

Yes, I color match LED to insert. If there's no good match, white does fine, just make sure it's not a real cool or warm white or else it can make the colors go off a bit. Also, be real picky about the differences between amber and orange, because you want to keep those looking true.

For white inserts, there are several different kinds of white LEDs. I like a cool white in my inserts as they pop more, but warm white looks more like the original incandescents. It's really a preference thing when it comes to that.

      That"s interesting.... I"d venture to guess a cool white would be somewhere in the blue spectrum, under a yellow insert , It would emit a greenish light.
I"m kinda wondering about ghosting [a faint flicker] in the off state. Does the mix of LEDS and bulbs stablize this problem? Would clipping the sine help?
Or is this not even a issue with modern LEDS?
