So staring into The Sun...
could provoke an arousal response? Well, once upon a time I might have agreed with you.
Italian scientists use fluorescent box to arouse sexually indifferent men
Chaps of a certain age who find their libido fading could do worse than stare at a glaring light source – though not the sort you might be thinking of. Scientists at the University of Siena have found the sort of lightbox used to treat sufferers of seasonal affective disorder enjoyed a boost in sexual satisfaction compared to …

Infact most SAD lights are a rip off, essentially most of them are just 6000-6500k lights that emit over 1000lm, however most are poor and dont produce more than 800lm.
Best bang for your buck is a 64w CFL 6400k hydroponic bulb if you want a cheap but effective SAD light.
More lumens the better, a 64w CFL should put out north of 4000lm (cost £13)

I use a 250W CFL as a high desk lamp, it's (ha!) brilliant. Fearsome amounts of light, means my crappy eyes can resolve fine stuff nicely. (Electronics fettling, requires reasonably good sight and fine motor control).
The only downside, this time of year, is that it brings in moths the size of B-52s.
I also mildly enjoy pointing at my 'energy saving' light...

"I wonder what effect staring at an illuminated computer screen all day has?"
According to my optician - anything which emits blue light damages the eyes. That is recognised as part of the spectrum of monitors and SAD lights - not to mention bright sunlight.
New lens coatings not only filter UV but also blue light. For older people especially this is extra protection against the risks of cataracts or retina damage.

Wonder where they got the bulbs from
I wonder how they managed to do this given that Italy is in Europe and in Europe, we are only allowed the
100 Watt53 Watt28 Watt, 11 Watt energy saving bulbs these days and nobody can work out how much light that actually is compared to the Watts of last year.Its like were going back to the medieval days with damp candle in the corner of the room.

CFLs are actually the ideal light source for this. The old incandescent tungsten bulbs generally give off a yellowish light, whereas CFLs with the right phosphor can be coaxed into a sunlight-equivalent colour temperature.
We have three 30W daylight bulbs in the lounge which are brilliant for banishing those wintry shadows.

Ideal until they fizzle out in about six months.
You might leap to conclusions about CFL factory location and quality, I couldn't possibly comment.
They're coming up for their fourth or fifth winter, so they're not going too badly.
We also have some 20W daylight bulbs which get used every day, and are now noticeably dim for the first 20 seconds or so. I guess I'll need to change them at some point.

a) you don't want to use bulbs, but rather fluorescents, as the title already indicates, b) there's no limit to the number of lamps fitted in an armature, and c) there are exemptions for bulbs for specific purposes, like heating (not that you want those anyway; see a) )
and nobody can work out how much light that actually is compared to the Watts of last year.
Funny how all the bulbs I bought the last couple of years had both the output in lumens listed, as well as the equivalent incandescent bulb wattage.
