I've been buying from fullspectrumsolutions for over 7 years now, and they've always been superb. Of the maybe 2 dozen or so bulbs I bought from them, I've had a light bulb problem only once, and they replaced the bulb right away.
In response to the previous posters:
Spearmint:
1. Full spectrum and flourescent are NOT the same--AFAIK, all true full spectrum are flourescent, but many flourescents are not full spectrum.
2. To get any real benefit for seasonal affect disorder from full spectrum bulbs, you need to have 10,000 lux at a distance of (IIRC) no more than 24". Obviously, just replacing lightbulbs won't do that--you're right when you say "not enough lumens."
3. The boxes are REALLY expensive. I built one myself for about $75, using high output compact flourescents, lined it with aluminum foil for better reflection, and it works amazingly well--really makes a difference in SAD for our household. Use it for an hour or so in the morning, and it works well.

www.firststreetonline.com products are NOT the same as those from fullspectrumsolutions.com. For starters, firststreet only sells lamps, not lightbulbs. Second, the quality of the light from firststreet is not nearly as good: the CRI (indication of color accurary) for firstreet is only 84, while the CRI for fullspectrum is 94.
So calling them the same is, umm, incorrect. But don't get me wrong, firststreet is a better price. But it's for a lesser product.

I put in a huge order last time, and I have some sitting around that I want to get rid of, so if anybody's interested, send me a PM--I'll sell them at 50% of the price fullspectrum wants (their per bulb price, not the bulk price). They're mostly the smaller ones--14 & 18 watt spirals, maybe a 24 or two.
