At 150W: 60° — 21,920 lm / 149.0 lm/W (3000K) | 23,130 lm / 161.7 lm/W (4000K) | 22,943 lm / 156.1 lm/W (5000K); 90° — 22,894 lm / 158.3 lm/W (3000K) | 24,005 lm / 168.9 lm/W (4000K) | 24,132 lm / 166.0 lm/W (5000K); 105° — 22,617 lm / 154.3 lm/W (3000K) | 23,952 lm / 167.3 lm/W (4000K) | 23,810 lm / 161.8 lm/W (5000K). Per-wattage breakdown at 120W and 100W available on the RAB spec sheet. Rated life 100,000 hours per IES LM-80 / TM-21 projections. L70 lumen maintenance standard.

Smart & Control Features

The RAB H22 supports the Lightcloud Blue (LC Blue) wireless control ecosystem and plug-and-play sensor accessories via the standard sensor receptacle:

• MVS50: MVS 15M height IP65 occupancy sensor — sold separately
• MVS50/LCB: LC Blue controller with integrated MVS sensor — sold separately
• PIR40: PIR sensor, max 12M height, IP66 — sold separately
• PIR40/LCB: LC Blue controller with integrated PIR sensor — sold separately
