Hi David:
Thanks for the link. I like them. The only problem is that you can not
order on line or by phone from Ikea and the nearest store is over two
hours drive away.
Have Fun,
Brooke Clarke

There are multiple versions, including wall-mount and one that clamps onto
the edge of an object like a bookshelf. Here is the family:

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.

Hi Poul:
Can the base be hung on a wall?
