fluorescent lamp in the use of ordinary, there is a more obvious phenomenon is in the home, often using a T8 lamp tube, but in supermarkets, shopping malls and other public environment, often using T5 lamps. Why is this so? That's because the light use efficiency of T5 is higher than that of T8. From the following several aspects can be a comparison:

1. Lighting effects and lighting quality: to sun light display color R=100 as the standard, the high performance T5 replacement
type fluorescent lamp r value is: R is larger than or equal to 85. The color rendering index of the light source is more and more big, the color of the light source is more and more close to the natural light, and the technical performance of the T5 is replaced by the fluorescent lamp, and the working frequency of the electronic ballast is above 40 KHz. Stroboscopic energy-saving lamps in the depth below 5%, the luminous flux is stable, no stroboscopic effect harm.

2 saving electric power and power saving rate. Power substitution ratio: the replacement of the lighting effect is improved, the proportion of its power substitution should be above 1:1.6W, that is, the power saving rate of 40% or more.

3 environmental adaptability: T5 series of products in the following conditions can be a reliable normal work: AC150V---260V voltage range, harmonic power grid, in the -15 C ~ 50 ten C environment. D. service life and failure rate: according to the high performance T5 replacement type fluorescent lamp R & D and production technology level. The average working time should be 10000 ~ 20000 hours, the failure rate should be 5 per thousand.
