I haven't seen anything specific on light levels for dry natural
science specimens but I presume you would be using same
international guidelines as used for museum objects.

In fact in Thomson's 'The Museum Environment' maximum level
recommended for "most natural history exhibits, including botanical
specimens, fur and feathers is 50LUX". Light level for leather,
horn, bone and ivory is recommended at 150LUX maximum.

Recommended UV level for sensitive material at 50LUX is generally
30microwatts/lumen and for material at 150LUX it is
