Well, I just mentioned the Zelco Max.5 in the other thread about the new Sony cover/wedgelight combo and only then figured out this light hasn't been mentioned on the forum yet.
What I love about this light is that it gives a perfectly even light distribution across the reader screen. There is, of course, an LED beam spot, but it's tiny and I just aim it at the bottom (metal) part of the reader so the actual screen is evenly lighted.
It also feeds off two AA batteries (rechargeables are OK, they last a while, but can't be more specific than this) and it is compact -- the LED and the stick it's attached to can be detached from the battery base and clipped onto its side.
What I don't like is that the light-stick wasn't made collapsible so that when it's attached to the side of the battery bay it's the same height.
Also, when I bought the light it was $19.99 + free shipping at the goinginstyle.com, however they have (about 5-6 lights I bought) later realized they made a pricing mistake and raised the price to $39.99 which could be considered steep, until you see the light in action.
I don't have the home-made pictures yet, here's the one posted at the online store I bought the lights from:

I will try to make and attach some pictures later on.
