U shape of this compact fluorescent lamp will pay for itself in the first year and continue to reduce bills long after that. Bulb lamps are small enough to fit neatly wherever you need extra bright light in the home. EFlite provide U shape  including T2, T3, T4, T5 U shape, and also can do 2U, 3U, 4U, 5U, 6U lamps. More choice, more convenient.
