I went with the KAEZI 85, as recommended in the top rated review on the parent’s linked one.
I opened the box around one of my roommates, and we were both astounded by how huge it was. “It looks like you’re building a death ray!” he exclaimed, to which I responded, “No, it’s a life ray.”
Here’s a comparison of it and a regular bulb (in the lamp I’m using it in now, which may get replaced), what it looks like off, and what it looks like on (there is no other change in lighting between those two shots). The camera, of course, is overselling the difference- I can look at it directly for brief periods, but I prefer for it to be behind or above me, or in the very periphery of my vision.
If you’re going to try bright light, I recommend the bulb I bought. It fits in normal sockets, uses a reasonable wattage, the light it generates is pleasant enough, and it’s cheap.
Changes in energy have been small, and most noticeable in the mornings. I have not compared against, say, my goLITE, largely because I don’t have a precise enough way to measure energy, but subjectively it seems comparable / possibly more effective. Given the tiny cost involved, I think it’s worth trying, but subjectively it isn’t revolutionary. (More careful statistics might show a larger effect.) It does seem effective at helping me stay up late, but since that’s something I don’t want, making sure to turn it off at a reasonable time is a recommended habit.
Yep, I had some trouble dealing with it because it’s so bright—had to put it on a high shelf (we can’t attach it to the ceiling). We’ve also found that they run quite hot compared to regular fluorescents.
There’s a review on those that mentions a comparison of others. I have the Alzo 45w bulbs that are $10/per (used to be cheaper, they are now more $/lumen than the ones you linked) But I have no basis for comparison in terms of lumen/efficacy in increased attention.
How much did this cost you?
The cheapest solution for very bright light that I’m aware of is something like these photography bulbs: http://www.amazon.com/CowboyStudio-105-Fluorescent-Daylight-Photography/dp/B004L75BGQ/ref=sr_1_2?ie=UTF8&qid=1358542854&sr=8-2&keywords=photography+lightbulb ($15/bulb, ~4500 lumens from each)
but I’d be interested if others have found cheaper solutions.

How is your uber-bright bulb setup working for you? I’m trying to decide whether to invest in the necessary stuff to try it out.

Your solution is cheaper than mine.
