Features:

• Up to 600 watts of incandescent or halogen, 150 watts of dimmable LED or dimmable CFL
• 600W / 150W MAX
• No tools required
• NEMA SSL-7A compliant

SSL is a new interface standard requiring that combining compliant dimmers and LED light bulbs does not affect reliability and meets or exceed the dimming behavior outlined in the standard.

Reliability

• Lutron's patented Clear Connect Wireless technology sets the
  bar for reliability
• works around corners and through walls
• Quiet frequency band is essentially free of interference, so your Caséta 
  Wireless dimmers won’t be affected by other wireless products.

These dimmers also help dimmable LEDs and CFLs perform better than when used with standard dimmers.
When dimming LEDs and CFLs with Caséta Wireless dimmers:

• lights will always turn on
• lights will stay on as you dim them
• lights won’t flicker (or will flicker less than with a standard dimmer)
