The detail behind the facts
UV is cumulative
Direct sun bleaches paint and yellows clear plastics over months, not years.
Collectors who skip this step usually discover the problem the hard way — a faded shoulder, a pitted alloy base, or a certificate that no longer matches the listing.
Glass does not save you
UV passes through ordinary glass; UV-filtering film does help.
Most first-time buyers only feel the real constraint after the piece has sat in its box for a season — by then the easy window to decide has already closed.
LED is safe
LED accent lighting emits negligible UV and little heat.
A ten-minute check at the shelf beats a weekend of restoration, and collectors who internalize the habit protect their whole display.
