Here is the family: http://www.ikea.com/us/en/search/?query=jansjo They all probably have the same LED head. If you don't need a long gooseneck, the wall and clamp versions are the cheapest way to get the head plus a short gooseneck. They give a circle of light with a fairly sharp cutoff at the edge of the circle. Think of it as something that will fit into many of the places where you would really like to have a fiber optic light source, but at 1/5 the cost. The little wall wart is a regulated constant-current supply (not constant voltage), which ought to make the light output relatively constant despite LED temperature changes and wire resistance changes. However, I find that the cheap inline switch has contacts that tend to get dirty or oxidize, and the LED flickers until I flip the switch on and off a couple of times to clean the contacts. If you're going to modify it anyway, install a better switch. I have two of these. One clamp-base is mounted on my computer desk, up high, where it illuminates my keyboard without washing out the monitor. The other has the weighted desk base, and it's useful as a reading lamp as well as illuminating things under the stereomicroscope, and looking inside cluttered equipment chassis.
