1
Designed for use with permanently installed LED, incandescent, tungsten halogen, or magnetic low-voltage transformers with halogen based lamps.
2
See bulb list at www.lutron.com/ledfinder
3
SSL-7A-2015 compliant when in forward-phase.
4
When using magnetic (core and coil) low-voltage transformers with halogen lamps set the dimmer to forward-phase. When using with dimmable electronic (solid-state) low-voltage
transformers set the dimmer to reverse-phase.
5
Operation of a low-voltage circuit with lamps inoperative or removed may result in transformer overheating and premature failure. Lutron strongly recommends the following:
• Do not operate low-voltage circuits without operative lamps in place.
• Replace burned-out lamps as soon as possible.
• Use transformers that incorporate thermal protection or fused transformer primary windings to prevent transformer failure due to overcurrent.
6
When using the dimmer / switch to control MLV halogen fixtures, the maximum lamp wattage is determined by the efficiency of the transformer, with 70%–85% as typical. For actual
transformer efficiency, contact either the fixture or transformer manufacturer. The total VA rating of the transformer(s) shall not exceed the VA rating of the dimmer / switch.

Includes Philips Advance Mark 10® ballasts, Sylvania®, Tu-Wire, and POWERSENSE®.
8
Neutral is recommended for best dimming performance, if available, but is not required for this load type.
