Textiles generally should be displayed at 50 lux (for 6 months).
Silk is especially light sensitive so this limit should be strictly
adhered to, however with light exposure the relationship is
reciprocal--if you shorten the time, the lux level can increase.  In
other words, if you exhibit it at 50 lux for 6 months you could also
shorten the time to 3 months and increase the level to 100 lux--the
overall exposure is the same.  Light damage is cumulative.
