It can switch the following type of loads:
• 6 amps (1500W)
Incandescent or mains halogen lamps
(recommended with integral safety fuse)
• 4 amps (1000W)
Electronic or wire wound transformers.

Lux set-up
The LUX is best set up when the ambient light is at approximately the
level at which you wish the lamps to switch on at. With the external
LUX adjuster set fully clockwise (Dark) wait for the lamps to switch off.
Rotate the LUX adjuster slowly anticlockwise (Dark to Light), at each
new position wait about 5 seconds for the TWSW to react to the change
and continue until the lamps switch on (diagram B).
