T5 Lighting — T5 lighting provides Bruco’s 14,000 square feet with both efficient light, as you can see in this interior picture, and heat. Winters in Texas can be cold, but Bruco has no traditional heating system in place. In the winter, we leave the lights on at night and between the lights and the RF welders, the building stays warm. (Note: The fan shown in this photo is used to dissipate the odor caused by the man hand welding an Airform.)
