Performance & Light Output

Lumen output varies by both wattage and CCT. At 50W, the SEAL4/E 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/E includes built-in 0–10V dimming compatible with standard building automation and lighting control systems. The /E suffix integrates a 90-minute emergency battery backup unit — the fixture automatically switches to battery power during an outage and maintains egress-level illumination for a minimum of 90 minutes in compliance with NFPA 101 and IBC requirements. For combined sensor + emergency backup configurations, refer to the /PIR/E, /MVS/E, /LCBS/E, or /LCBS/MVS/E suffix models.
