SCFL-7比普通的同功率熱陰極節能燈高20％，比白熾燈高五倍；表麵亮度分別比後二者高一
倍和五倍；壽命分別比後二者長三倍和二十倍；開關次數則達到一千萬次。燈的色溫在2700K到6400K。配以適當燈具後，可適用於工廠、學校、商場、賓館、百貨公司、街道、隧道、廣場、庭院、航站樓及候車廳等場所照用。現有的功率有5W，7W，9W，11W。
SCFL cold-cathode lamps save more than 20% energy than the hot-cathode lamp counterparts, and the energy-saving efficiency is five times more than incandescent lamps. However,SCFL cold-cathode lamps do not compromise in surface brightness, lifespan, and the number of on-off. The surface brightness of a SCFL cold-cathode lamp is one times more than a hot-cathode lamp and five times more than an incandescent lamp. The Lifespan of aSCFL cold-cathode lamp is third times more than a hot-cathode lamp and twenty times more than an incandescent lamp. The number of on and off for aSCFL cold-cathode lamp is more than one thoustand times.The color temperature of aSCFL cold-cathode lamp is between 2700K and 6400K. With an appropriate package, a SCFL cold-cathode lamp is suitable for factories, schools, stores, hotels, shops, streets, tunnels, squares, gardens, airport terminals, and waiting halls.
There are 5W, 7W, 9W, and 11W types of SCFLcold-cathodelamps available.
