| Designed
to help maintain night vision while making reading
the pages of an almanac or even sections of a chart
easier, the Weems & Plath LightWedge provides
a 'sheet' of red light across the paper without throwing
it into the user's eyes. Measuring 9 1/4inx6 3/4in,
the acrylic sheet is actually a wedge shaped lens
(or series of lenses) that distribute the light from
red LEDs placed along one side. These
LEDs are powered by four AAA batteries, which should
provide 40 hours of light before needing to be renewed.
A button switches the lights on and off, but also
sets one of two light levels.
