The two most common types are 40-watt, 4-foot (1.2-meter) lamps, and 75-watt, 8-foot (2.4-meter) lamps. Now, tubular fluorescent technology has improved. New products such as T8 and T5 are much more energy efficiency than T12 (T12 – 57 lumens/watt; T8 – 92 lumens/watt; T5 – 103 lumens/watt).The two most common types are 40-watt, 4-foot (1.2-meter) lamps, and 75-watt, 8-foot (2.4-meter) lamps.
