Best LED color to mimic incandescent lighting

Dan, Since you seem to be the wizard with LED's around here I figured I would pose this question to you. So I am creating some paper lamps and I'm looking to power them with ultra bright low power LED's, My goal is to make them green laps with the option to use a battery pack with a solar cell. So with that in mind what do you think would be the best selection of LED's for me, I was looking at the Luxeon Star LED's, but was wondering what color I should go with if I want that incandescent look, I was also thinking of creating a single rgb rig to control the color of the lighting for each lamp, your input will help me decide. Thanks in advance, Joshua AM

I color my own leds. :) leds dont produce a lot of heat. Ive heard its somewhat around 60 degrees farenheit. So what i do is take glue, usually craft glue, and mix it with food dye. One to 5 drops of yellow should create the warm cream color you are looking for. The great thing is that the glue can be peeled off if you feel youve went to dark/rich or didnt like it :) also a slightly orange color might do it. I sometimes use glue to diffuse the light so it is less beam like, being as they are directional lights.

That is such a simple brilliant idea. I bought a cheap ass (maybe not so safe) Chinese smd e27 light bulb and I didn't like the light colour, so I was thinking about replacing some smd leds for red/yellow. The problem is red/yellow leds have a different voltage then (warm) white, so a simple swap isn't possible. I just might happen to have some food dye! :D

My impression is that the "warm white" LEDs are meant to look like incandescents, while the "cool white" LEDs (or just "white") look more like fluorescent lights. I don't know if you can get an effective "white" out of todays RGB leds; the brightnesses of the individual color chips tend not to match up as nicely as you might like, and the individual colors tend to be "peakier" than the phosphor emissions of the "white" LEDs.

He asked to post any question to him to the forum so that everyone may learn from these discussions.
Ah.

make sure the led you get has a wide viewig angle, like higher than 100 degrees
