T5 Fluorescent Bulbs

Fluorescent lighting is an ideal lighting source in many spaces, including residential, industrial and commercial locations. With T5 fluorescent lamps from Warehouse-Lighting.com, you get high-quality iridescent lamps that are perfectly suited for use in fluorescent lighting structures. A T5 lamp is built with smaller-sized tubes which make them great for fitting into narrow spaces. Despite a narrow width, however, T5 fluorescent lamps are just as powerful when it comes to their luminosity factor. Their size is also a benefit since these lamps are known for their superb beam control.
