LTG controllers and LED'S.

Postby uccsa1 on Mon Oct 21, 2013 6:30 am

I do realize that one can use LED's with the new controllers. What I am wondering is how you all compensate for the LED's lack of the color yellow. Yellow and blue make green, of course, but with LED's they emit white. How do I compensate to keep my DECO and any glass lenses looking the way they should? Yellow plastic?
easy way is harder than it looks

Not following you. Are you asking can a LTG drive LEDs? Or, if A shaped LED bulbs in a reflector create the correct colors through vintage glass?

On the latter, I run CREE A19 2700K 60w bulbs in my CH AD with Smileys. Yes, the 2700K and bluish lens makes a authentic green-blue "green". I have to set the sockets all the way back to get the focal point right. Ideally, I'd use the CREE A19 2700K TW series bulb, they have a 93CRI and would be most accurate. But I got these bulbs for $5 at HD.

I finally get what you're asking. Like made in china mentions, LED bulbs are a lot like fluorescent tube lamps, they come in a variety of colors from warm to daylight, so you can get the slightly tan glow from an LED bulb like you would from an incandescent if you go for 'warm'.
