Query: Not enough light, & too narrow a beam, for desktop use

I was hoping to use this product to illuminate my desktop keyboard, which I use at night. Unfortunately I can't get the beam to cover the entire keyboard, and even where it does cover it's not bright enough for me to read the keycaps.I know it's advertised for notebook, so it's my own fault - notebooks have smaller keyboard and also the low light trades off against low battery draw. So it might be ok in a notebook context (I have the luxury of a lighted keyboard on my MacBook so don't have that problem).Meanwhile I'm still looking for a good solution for my nighttime problem. Sigh.
