We carried out a MA conservation project at the Institute of
Archaeology, UCL, looking at the LightCheck sticks and found them to
be good in low light levels as they change colour more quickly than
Blue Wool Standards.  They were very sensitive to UV light and will
change colour very quickly if exposed to direct sunlight.  They
could therefore be useful to monitor the integrity of UV filters.

Some of the colour changes were hard to tell apart.

These test were carried out only over a few weeks.  If you want any
further info get in touch.
