Light Output & Performance

The integrated LED produces 6,050 lumens at 55W with 110 lm/W efficacy. 90 CRI and R9 at least 50 support accurate color rendering, while 4-step consistency helps coordinate multiple fixtures. Choose 2700K, 3000K, 3500K, 4000K or 5000K using the fixture DIP switch. Rated life is 50,000 hours at L70, and separate bulbs are not required.

Electrical & Installation

The constant-current Class 2 driver accepts 120-277V at 50/60Hz. SMP2X4 is designed for surface mounting, avoiding the hanging drop of a pendant fixture. Use in indoor dry and damp environments; the individual sheet specifies that this model is neither IC rated nor airtight.

Use a compatible TRIAC/ELV dimming system for brightness control down to 10%. Set color temperature at the fixture DIP switch during installation. The sheet also lists suitability for closet use under NEC Sections 410.16(A)(1) and 410.16(C)(1).
