I think eprom erasers use a higher wavelength about 2,500 Anstroms and
black-light lamps are likely centered at the edge of visibility maybe
3,000 to 3,500 Angstroms? Visible light begins at about 4,000 Angstroms.

Apparently with an IR camera, hot parts show up and cold parts show up.
The theory being that cold parts are dead... well it works for humans!
