These easy to use timers have a single select knob that clicks to any of 16 time settings. Settings include an accelerated 18 hour day cycle running ON 6 hours / OFF 12 hours. Thirteen normal 24 hour day settings cover ON 8 / OFF 16 to ON 20 / OFF 4 in one hour increments.

Continuously ON and OFF settings are also included. The Lamp Pro sequences two outlets on, 20 seconds later the next two, and 20 seconds later the final two. This reduces electrical problems. Turn off has a 5 second delay. The LP-120S (120v 15A) uses standard 120v type outlets and power cord plug. The LP-240S (240v 30A) has 240v outlets and an 8' power cord with unterminated wires. It can control up to six 1000W lamps.
