In most archives and libraries using flash is forbidden. Of course it is annoying for other visitors and they fear damage by the bursts of light to the paper. AFAIK there is hardly any UV or IR in xenon flash so it shouldn't do much damage.
I found a better solution to the horrible lighting conditions: portable LED lights with rechargeable batteries. The ones I bought were 15 Euro's, they have 30 ultra bright white LEDs, they burn up to 4 hours per charge.
I do need a way to diffuse the light however, they throw their rectangular bundle almost straight forward. And I do need to find the ideal places to avoid shining/mirroring spots on paper or glass/plastic.
