7.5 THE PROOF
The best way to prove this is to demonstrate the problem. LSC staff carry a pin spot, a 12v
desk lamp with transformer and a mirror ball motor with them when they do
demonstrations. The LSC PTFD dimmers can control all of these devices without any
problem. Almost all opto-isolated dimmers fail this demonstration completely. The mirror
ball motor does not start or if it does it never stops. The pin spot flickers at low levels and
the 12v desk light cannot be dimmed and stays on at full brightness as the dimmer channel
is dimmed up and down.
LSC GenVI dimmers are PTFD dimmers.
