LED lighting produces a different color than strobe in a softbox (my standard lighting choice). The overall color is the sum and average of all the individual LEDS in the panel.
I have two brands of LED panels... Flolight and Fancier. The Flolight is a pricier panel... at $800 for a 12"x12", compared to $250 for the same size Fancier.
The Flolight costs more because it has a dimmer, because it can be run from a DC battery, and because the color rendition or spectrum is smoother than the Fancier. It's color cast isn't perfect, but that can be fixed with filtration. What's more important is that it's SPECTRUM is closer to that of flash or daylight.
I discovered that better spectrum by photographing a GreytagMacbeth ColorChecker Color Rendition Chart. It's color patches tell the tale of how much light along the color spectrum the light is emitting. Comparing the Flolight to flash or daylight, the color patches stay the same relative brightness and saturation. But comparing the Fancier to flash or daylight, some patches get lighter and others get darker... meaning that the Fancier has spikes or dip along the color spectrum. Those absences or excesses can't be corrected with filtration.
As a result I prefer to use the fancier as an accent or background light, where broad spectrum color isn't as critical.
You get what you pay for!
