Light Output & Performance

The integrated LED delivers 1,900 lumens at 24W with 79 lm/W efficacy and a 110-degree beam. Greater than 90 CRI and R9 at least 50 support accurate color rendering. The overview and features specify 2700K-6500K tunable white with smooth transitions; default CCT is 3000K. Rated life is 50,000 hours at L70; separate bulbs are not required.

Electrical & Installation

The constant-current Class 2 driver accepts 120-277V at 60Hz. This fixture is designed for surface mounting, with a low-profile form that avoids a hanging drop. Control dimming through the Lightcloud Blue mobile app and compatible devices; the sheet warns that it will not operate properly when connected to a standard incandescent dimmer or dimming control.

Connect directly to Lightcloud Blue using Bluetooth, without a gateway or hub. Configure on/off, dim level, color temperature, schedules and scenes in the app. SmartShift supports circadian lighting synchronized with local sunrise and sunset. The sheet lists range up to 60 ft through standard building materials or 200 ft clear line of sight; brick, concrete and steel may require additional Lightcloud Blue devices to extend around obstructions. The fixture is UL listed for dry, damp and wet environments and suitable for closet installation under the listed NEC provisions, but is not IC rated or airtight.
