Well I've found one on ebay, ordered it and here it is.
From the left: a bulb we use in our bedroom (11W), old 500W bulb, and new 100W CFL light bulb

I have a cubelite cube and I use the bulb for illuminating the stuff. Except OurEcoHouse website I also run publicdomainpictures website (http://www.publicdomainpictures.net) where I put my pictures so people can use them completely for free. You know, just giving something to the community. :-)Shirlz wrote:WOW that's BIG!
How do you use it for photography? I'm intrigued.
