You can get CFL bulbs at the 105-watt level, and they're huge but bright and daylight-balanced too.
I recently bought this: http://www.amazon.com/gp/product/B005FRCUHY/ref=oh_details_o06_s00_i00
Unfortunately out of stock now, but it was under $30 for a 2-pack at the time. Note that I had to discard a smelly 65W bulb from Square Perfect, but LimoStudios seems able to handle its own heat. 2x 105W CFLs makes a brilliant blue-white light that does seem a bit like daylight.
If anyone knows of a floor lamp that will shade standard-socket light bulbs that are literally a foot long, I wouldn't mind a recommendation. My current setup is kinda hacky.

4 pack, 65 watt, Premium Loadstone Studio Day-Light Studio Light Bulb. Looks like the same brand of bulb. $23.70 shipped. The 65 watt bulbs are cheaper per lumen, and more efficient in lumens per watt.
Note that although the Square Perfect bulb also had the green band, just like LimoStudios, the Square Perfect bulb gave a dreadful smell and the LimoStudios ones didn't.

The Lime Studios lights are at least not labelled as Square Perfect, and are listed as 6500K instead of 5500K. But I to think that any product that looks the same except for labeling come from the same manufacturer, but marketed through different outlets with customized labeling.
Probably still the same lamps. Maybe Square Perfect got a bad match. Maybe you just got a bad bulb. Or maybe it's a design flaw. The fact that they're cheaper than others gives me some pause that they have a problem. I was hoping the relative inexpense was an economy of scale issue with the most popular size.
But when they come in, I'll report back on whether they smell.
Do they smell?
No smell issues for me.
these look like a significantly better deal than anything I've seen on ebay or amazon.
