Normal household timers are not built to take the high inductive loads produced by HID ballasts. If used with an HID ballast - the contacts inside the timer that open and close the timed circuit will overheat and weld together - breaking the timer and leaving your grow lights permanently on.

This means no separate contactor is required and saves you money. It has a 96 switching operations within a 24 hour period (every 15 minutes). This timer is suitable for timing one 600w HID ballast or up to 6 x 200w CFLs. It has a robust 'inline' case design with socket and timer dust covers.
