We bought three of these.

We've tried to put them around the room evenly. You can see all three in the right picture (one in the foreground). We'll report back in a few weeks about how much it helped.

How are you measuring how much it hurts/helps?

Completely non-rigorously. I'll probably just look at my hours, and reflect on how I feel about its effect.

I'm curious how this worked for you. (The lighting, not particularly the experimental method.)

Unfortunately not enough of an effect for me to claim anything. I do like it brighter though, so I will continue using the lights.

Okay -- thanks for the results. :)

It looks as though you'll soon be needing some diffusers...

The nice thing about CFLs is that you can put really quite bright ones in small desk lamp housings - because they dissipate a lot less heat. Only problem is physical size of the bulb.

The CFL I tried tended to give me headaches.

YMMV. Horrible yellow or daylight spectrum?

No yellow tinge. Made by Feit Electric.

Well, that sucks, since CFLs are only going to increase. There's a pile of crank sites about CFLs and migraines; closest to non-crank I can find quickly is this Australian government site, which says this from CFLs (as opposed to the older ones that flicker at 50/60Hz) is generally badly set-up lighting.

Your "poorly set-up lighting" is a reference to this:

the primary cause is likely to be glare, highly contrasting, or inappropriate light levels. These problems are a result of poor lighting design rather than a feature of fluorescent lamps and can occur with any lighting technology if used inappropriately. Light fittings that enclose lamps and distribute light evenly without compromising light output and efficiency can help avoid these problems.

Poor set-up is unlikely to be the cause in my case because I did not make any changes except to replace an incandescent bulb (on my desk) that never gave me any problems with a CFL of similar brightness.

I do not dislike all fluorescents. For example, the cold-cathode fluorescent lamps in my monitor and my best friend's TV give off completely-unproblematic very nice light. (The light from the two LED-backlit devices in my life on the other hand is not nearly as nice.)
