The most efficient canopy light ever.

MASI is easy to install for retrofits and new construction.


LED Canopy Lights

DLC Premium.

MASI was awarded DLC Premium classification* for its exceptional performance, qualifying it for the highest tier of energy rebates. It has the highest efficacy rating of all canopy fixtures on the market today!

*All 120-277V models.

Easy installation for retrofits and new construction.

MASI is designed to easily replace Scottsdale ® and other popular fixtures.

Install MASI in canopies with single-deck construction (access to junction box from above the canopy is required).

Standard 4" hole installations:

  1. Disconnect and remove old fixtures (if applicable) and insert the wires and mounting stem on the MASI through the hole.
  2. Two spring clips on the stem compress while being fed through the hole and spring back to secure the fixture in place once the stem is pushed entirely through the opening.
  3. Installation is completed from the top of the canopy by bolting the junction box to the stem, wiring the fixture and latching the cover to the junction box.

Additional retrofit options:
An optional retroplate allows for installation in openings from 4 to 6.5 inches in diameter. Additional retrofit options are available upon request to replace virtually any existing fixture. Please contact RAB Customer Service 1-888-722-1000.

Stiffening brackets

Stiffening brackets prevent deck sagging and discreet weep holes prevent water from collecting on fixture.

Optional retroplate

Enables installation in openings from 4" to 6.5" in diameter. Additional retrofit options available upon request to replace virtually any existing fixture.

Best-in-class efficiency means big-time savings.
