Sam, you need to tell us more about 'how much' light-tightness you want and if
the ambient has some or no light at all.
As an extreme example, in testing a photographic darkroom for light-tightness it
is common to hang a few rolls of unexposed film in the room for an hour, process
them and examine the film for exposure. For that level of light-tightness, a
LEGO sensor would not work.

| Basically there's enough light coming through that it would expose film quite quickly. Also, the ambient does have light in it. If the lego sensor isn't sensitive enough, could I easily replace it with another? (20 years ago, 14-Jul-04, to lugnet.robotics.rcx)
