That's right -- illumination by inverse square law :O) You need to
get within a couple of centimeters at highest magnification, but the
lamp head is small and easy to position. (Or you could buy two --
double the intensity and get the twin head configuration you're used
to.)

The old style twin antennae lights with a rheostat are about $600 but are old technology. I wanted LED lights which are cold and I would think more easily replaceable in the future. The Schott EasyLED Spot Illuminator costs about $1,000 in Australia for a single antenna light. This seems just too much for what you get. How do you regulate illumination on the desk lamp? Do you just move it closer ?
