Reply to "Florescent light Replacement"

I'm with @Mike CT- color temperature is very subjective and does have a major effect on what our brains interpret as color.

I run the facilities department at a University, all of the lay-in fixtures we buy now come with a set of dip switches to set color temp. One fixture can go from 3000K up to 5600K. We have found that most people prefer 3500K in today's office environment.

The bad part of LED fixtures is there's no re-lamping anymore. If the fixture dies, then the whole thing needs to be replaced. I've probably changed more fluorescent lamps and ballasts over my career than I could count, which I always found frustrating. I'm still on the fence if swapping a whole fixture is better than re-lamping.

Here's a good comparison. When I was putting a building together a while back I shot some pictures on my bench. I have 3500K overhead lights and a task lamp that's 5600K (all fluorescent). The wall on the left is under the 5600K light., right under 3500K.
