Performance & Light Output
Lumen output varies by CCT — 4000K delivers the highest output at every wattage setting. At 230W (100%): 34,000 lm / 148 lm/W (3000K) | 36,000 lm / 157 lm/W (4000K) | 35,000 lm / 152 lm/W (5000K). At 184W (80%): 28,000 lm / 152 lm/W (3000K) | 30,000 lm / 163 lm/W (4000K) | 29,000 lm / 158 lm/W (5000K). At 138W (60%): 22,000 lm / 159 lm/W (3000K) | 24,000 lm / 174 lm/W (4000K) | 22,500 lm / 167 lm/W (5000K). At 92W (40%): 15,500 lm / 168 lm/W (3000K) | 16,500 lm / 179 lm/W (4000K) | 16,000 lm / 174 lm/W (5000K). Rated life 50,000 hours per IES LM-80 results and TM-21 projections.
Smart & Control Features
The HBU-240W-UV-CCT includes a standard 0–10V dimmable driver and supports plug-and-play sensor accessories via the integrated sensor receptacle:
- Plug-and-Play PIR Sensor: ANT-6-4T (standard) | ANT-6-4T-BLE-SR (Bluetooth) — sold separately
- Plug-and-Play Microwave Sensor: ANT-5-4T (standard) | ANT-5-4T-BLE-SR (Bluetooth) — sold separately
Bluetooth sensor variants enable wireless group control and scheduling without a separate gateway. A Transformer Box accessory is available to convert this fixture to high-voltage (HV) input, reducing SKU count and inventory pressure.

great servive
We recently bought several of these lamps to test out in our collision repair shop. We hung 2 of them next to our old HID lamps and immediately bought 14 more to complete the installation. They are extremely bright, have great coverage and we no longer have shadows in corners and along walls. The energy savings alone makes them worth buying!
These lights work really well in our facility; they are fairly robust and last a long time
The lights were fine. The issue that arose for me was their claim of shipping within three business days and that "all lights are in stock". I placed three different orders. The first one had not shipped within three weeks. After I inquired about it, I was told there was a communication error and the lights would ship immediately. It still took a week. Both the second and third orders took multiple weeks to ship, and both times they only shipped after I inquired about them. It is clear they do not stock these lights and instead are just a middle man.
