Energy-saving lamps are divided into U-shaped tubes, spiral tubes and straight tubes due to the different shapes of the tubes.
1, U-tube energy-saving lamps: tube shape: 2U, 3U, 4U, 5U, 6U, 8U, etc., power from 3W-240W and other specifications.
2U, 3U energy-saving lamps, diameter 9mm----14mm. The power is generally from 3w to 36w. Mainly used for civil and general commercial environment lighting. In terms of use, it is used to directly replace incandescent lamps.
4U, 5U, 6U, 8U energy-saving lamps, tube diameter 12mm----21mm. The power is generally from 45w to 240w. Mainly used for industrial and commercial environment lighting. In the way of use, it is used for direct replacement: high pressure mercury lamp, high pressure sodium lamp, T8 straight tube type fluorescent lamp.
2, spiral tube energy-saving lamps: spiral ring diameter, divided into small ring diameter and large ring diameter. The small ring diameter is generally about 50mm, and the large ring diameter is generally about 100mm.
The number of spiral loops is: 2 turns and a half, 3 turns and a half, 4 turns and a half, 5 turns and a half, 6 turns and a half, 7 turns and a half, 8 turns and a half, etc., and the power is from 3W-240W and other specifications.
3, bracket energy-saving lamps: T5, T8 straight tube fluorescent lamps are widely used in civil, industrial, commercial environment lighting. T5 main use power: 14W, 21W, 28W, T8 main use power: 18W, 30W, 36W, because T5 light effect is higher than T8, has been the market mainstream.
