I tried my 505's travel light on my 900, clipped to the folded back soft cover --

It is a 90% solution and I may live with it. I love the light quality of this cold cathode tube. The issue is, to get the most even coverage I either have to clip to the side (or top if in landscale mode) or else position it just barely angled above causing a bright reflection in my usual portrait mode. I'd say the side-spill makes the light quite even in landscape but I see some intensity fall-off at the bottom in portrait.
