There is also a small germicidal lamp, less than 5 inches (120mm), I
used it for more than 5 years erasing eproms, very small, fast (less
than 7 min) and easy to build inside any plastic case.  Several UV lamps
can be used to erase windowed chips, some works better than another
(this is because the UV frequency, irradiation intensity...), but it
needs to irradiate UV, so the body should be crystal (not glass) and the
famous black bulbs will not work, glass or any coating (as the black
ones) blocks the UV light.  Just take extra care to never look at the
light, it can create severe problems at your eyes retine.  Build it
inside a box (plastic, metal) in a way that you cover the chips (on the
table) with the box upside down. Install a power switch that turns on
the lamp only when it is resting upside down over the table and the
chips.
