Q: Does this require a neutral connection?
A: Yes, this requires a neutral connection.

Q: Will this dimmer work with dimmable LEDs?
A: This control is compatible with many dimmable LEDs, however we can only recommend dimmable LED bulbs that we have tested and deemed compatible. In order to be sure the LED product will dim to your standards, please check Lutron's LED Selection Tool to see if they have done testing and can stand behind the dimming performance. If the bulb you are using does not appear on the approved list, please contact the LED manufacturer who may have done testing and can make a dimmer recommendation.
