James Moss asked whether LED lights emit uv radiation. LED lights produce a narrow spectrum of light. You can buy LEDs which specifically produce uv and almost nothing else, but white light LEDs will not emit uv radiation at all.
Visible light is still damaging, so you still need to calculate the annual exposure (strength in lux multiplied by hours per year) and expose light-sensitive materials to less than 150,000 lux-hours per year. It really helps if you can limit light exposure on objects when no-one is looking at them.
