Default The wrong kind of light

I've just ordered 4. Would prefer lower wattage too. SWMBO won't accept 6500K
ones apart from the one in the futility room. The usual 2700K slow start ones
are abominable, like crap lady's makeup in colour. Whatever happened to 3500K
which would be more acceptable.


They aren't acceptable to most people, which is why they will be hard
to find. The lux level required to make 3500K look acceptable (lookup
Kruithof Curve) would be hard to achieve with CFLs - you need several
linear fluorescent tubes, which is why you'll find 3500K in fluorescent
tubes, but not CFLs.

The 5000K and up lamps and really just gimicks - you are effectively
using a blue coloured lamp, because you will never get the lux level high
enough for 5000+K to look natural. You would have to line most of the
ceiling with fluorescent tubes.
