The detail behind the facts
Cumulative
Direct sun bleaches paint and degrades plastics over months, not years.
A ten-minute check at the shelf beats a weekend of restoration, and collectors who internalize the habit protect their whole display.
Glass is not a shield
Ordinary glass passes UV; UV-filtering film does help.
It costs nothing to get right at purchase time and is disproportionately expensive to fix later, which is why studios bake it into their care documentation.
LED is safe
Quality LED accent lighting emits negligible UV and little heat.
The difference shows up years later rather than on unboxing day, which is exactly why it's easy to underestimate when comparing listings side by side.
How collectors apply this
- Never display in a south-facing window.
- Filter film is cheaper than a refinish.
- Choose 2700–4000K LEDs for display lighting.
Common mistakes to avoid
Letting humidity swing with the seasons because the shelf 'looks fine' until the base blooms.
