Verde Solutions, LLC custom built an Industrial Highbay capable of achieving 125 foot candles to fit the needs of Weldbend’s facility. The feature that made this light unique to the industrial lighting market was the up-light module that eliminates the “cavern effect”, which often occurs in large facilities (see image 1 on the next page for a comparison). Another feature included the full wireless controls of the fixtures daylight harvesting sensor to distribute light efficiently. This sensor offsets energy consumption by adjusting the amount of lighting used within a space based on the amount of available daylight.

Occupancy sensors were installed for better security and increased efficiency. The Industrial highbay is suspended at approximately 30ft. and Weldbend, being a high volume manufacturer, needed an easy to clean facility including the ceiling. Verde was able to qualify the highbay for the IP65 rating allowing the fixture to be power washed.

Weldbend’s LED retrofit consisted of Verde Solutions replacing 987 HID highbays with 987 LED highbays. There was a significant reduction in maintenance and replacement costs going from the HID rated life of 10,000 hours to the LED rated life of 50,000 hours. Weldbend would have to replace their existing HID highbays 5 times over the lifetime of just one Verde Industrial Highbay
