Traditional safelights must use a color filter, but still must operate at very low light levels, This is because, short of hugely excessive cost, those filters pass a range of light wavelengths. They may look red or amber, but they also pass relatively small amounts of light to which photo paper is sensitive. By comparison, the LED passes a very narrow and specific range of wavelengths, so if properly specified, a safelight using them will not "leak" unsafe wavelengths. This allows them to be much brighter, as the paper is far more "blind" to that light, regardless of its intensity.

I use a 3W red LED lamp inside a "lamp spot" pointed to the ceiling. It does very well, have done the Kodak and Ilford safelight test and passed on both.
