Performance & Light Output

Lumen output varies by both wattage and CCT. At 25W, the SEAL2/E delivers 3,300 lm at 5000K, 3,400 lm at 4000K, and 3,250 lm at 3500K. At 20W: 2,700 lm at 5000K, 2,780 lm at 4000K, 2,660 lm at 3500K. At 15W: 2,070 lm at 5000K, 2,130 lm at 4000K, 2,040 lm at 3500K. Peak efficacy is 142 lm/W at 25W / 4000K. All settings deliver 80 CRI. Rated life: 100,000 hours (L70).

Smart & Control Features

The SEAL2/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. Optional occupancy sensor suffixes are also available on other SEAL2 configurations.
