After much searching online, I discovered that the closest thing I could find to the LED light I mentioned a few days ago is the one pictured here which, apparently, you can get for about $2 from Amazon.com.
I got mine for $4.98 at Half Price books, but if you’re doing an Amazon order anyway, tossing in one or two of these might not be a bad idea. (Ordering JUST a light would be a waste of shipping costs.)
This is the light that’s working for me, at the moment. As with any such thing, your mileage may vary.
I have to ask, though, what’s your ideal booklight? What do you use now?
