Re: Work lamp
What kind of lamp is it? LED? Fluorescent? Incandescent-bulb? Does it have a separate transformer/controller/ballast-box or does the mains cable just run direct to the bulbholder??
It only takes a miniscule amount of leakage to light one of the usual neon-testers: the "creep resistance" of an old decaying bakelite bulbholder, or the mere capacitance of the live lead to the metal lamp as it runs through the metalwork, could be enough to cause such a tester to light.
