Recently had to replace a few early LED "bulbs" that were first on the market types. All had only the soft white color of 2700K. The new ones I replaced them with are all 5000K "daylight" color rendering. Most were watt for watt equivalents, but seem brighter. Even had my son commented (he doesn't notice ANYTHING ) that they were brighter. All in how the eye perceives light, but as I've gotten older, the "whiter" lights seem to illuminate things more clearly and cause less eye strain. Probably just the opposite since the waves are more toward the blue end of the spectrum and that usually induces MORE eye strain. Oh well, I can see better with them vs. old T.E. style color.
