I badly need some better lighting in my study. It's only a small room, and while it does have almost wall-to-wall and ceiling-to-floor windows on one side, they're North facing and I'm nocturnal.
Currently, there's a rather miserly 23W CFL - which:
a) isn't particularly bright
b) is 'tungsten' colored
c) Has a sucky CRI which is probably about 75
I've been thinking about what the best thing to do was.
I have my desk in one corner, and a large wardrobe next to it, which goes pretty much to the ceiling.
Room is about 10 ft x 8 ft.
I've been thinking of 2 options:
1) Put a pair of decent fluorescent strips in the middle of the room.
Problems
what sort of luminaire would be best? I like those metal reflector ones but am concerned that they don't provide enough diffusion (hence why they're normally recess mounted).
I worried that I wouldn't get enough direct illumination over my desk, and that by having the light behind me, I would have to work in my shadow.
Might cause glare on my monitor if the light source is behind
2) Put a pair of uplighters in - one above my desk and one diagonally opposite. I was thinking 70W or 150W HQI Daylight lamps.
Problems
Is this excessive? I can imagine 2x 70 being adequate, but 300W of HQI lighting might be way over the top. Still I probably get a bit of SAD, so it might not be a bad thing.
They take ages to warm up - probably means I need to keep a CFL in there for backup.
How much do these suffer from flicker? Can you get ECG for them?
Do any manufacturers produce lamps with 95+ CRI?
