Quoted from arcadenerd925:I think what they were talking about was the color tint depending on the type/model/PN/spec of the LED used (although, being an RGB LED I would find that odd, but I'm no expert). If your saying it started out bright white, and then later turned yellowish, that would be pretty strange.
However, this topic is being beat to death, lol. Time for a beer.
As i said in another thread. Led's are sensitive to voltage drop, and White require The most power.
If lights start to change from White, i would bring my trusty old volt-meter.
