Does daylight mean blue, or are these lights not right?
I didn't want warm ones as they look beige.
Problem is I got 10 of them on ebay, as they were a good price.

That does not always bode well :-)

White LEDs are a hybrid of a blue LED, plus a florescent coating to turn
that into white light.

Poor quality phosphors tend to emit a fairly "spikey" white with lots of
spectral gaps, and a fair amount of the LED's blue bleeding though.

Anyway, i've put one up in my office at work and I feel like i'm, in a
fishtank, I know things aren't nearly right as after a couple of hours
up there I went downstairs where we have some orange clipboards and they
appeared to be glowing.

I wonder if they can they be toned down at all?
I need more than one light so if I fitted a warm one adjacent, would I
get something more natural overall?
It probably doesn't help that the room is painted lilac, that's going to
change, I wonder if I could improve matters with a different colour decor.

Good quality daylight can look fine - so long as its bright enough. The
eye is attuned to daylight "colour" light at high intensities - making
it feel bright and sunny. At lower levels it just feels cold and blue.
