Performance & Light Output

Lumen output varies by both wattage and CCT. At 50W, the SEAL4 delivers 6,000 lm at 5000K, 6,800 lm at 4000K, and 6,500 lm at 3500K. At 40W: 5,400 lm at 5000K, 5,560 lm at 4000K, 5,320 lm at 3500K. At 30W: 4,140 lm at 5000K, 4,260 lm at 4000K, 4,080 lm at 3500K. Peak efficacy is 142 lm/W at 50W / 4000K. All settings deliver 80 CRI. Rated life: 100,000 hours (L70).

Smart & Control Features

The SEAL4 includes built-in 0–10V dimming compatible with standard building automation and lighting control systems. Optional occupancy sensor and wireless control suffixes extend functionality:

• PIR Sensor (/PIR): Passive infrared occupancy sensor; max mounting height 40 ft.; detection range 40 ft. diameter at 40 ft.
• Microwave Sensor (/MVS): Microwave occupancy sensor; max mounting height 50 ft.; detection range 50 ft. diameter at 50 ft.
• Lightcloud Blue PIR (/LCBS): Bluetooth Mesh wireless PIR sensor — programmable via Lightcloud Blue mobile app; no gateway or hub required.
• Lightcloud Blue Microwave (/LCBS/MVS): Bluetooth Mesh wireless microwave sensor — programmable via Lightcloud Blue mobile app; no gateway or hub required.

Lightcloud Blue (LCB) is RAB’s Bluetooth Mesh wireless lighting control platform. Using RAB’s Rapid Provisioning technology, devices can be commissioned quickly for residential and large commercial applications via the Lightcloud Blue mobile app. Compatible interior DLC system: N1XMLOEATBA; exterior: NHCZ2BIA17L. Sensor settings are adjustable via the Lightcloud Blue app; all other sensors require the MSR1 Remote.
