Comparison of T8 lamps and energy-saving lamps

Advantage
Compared with the same brightness of energy-saving lamps, T8 lamp is cheaper than energy-saving lamps. Compared with traditional incandescent bulbs, the energy conversion efficiency is better, less heat, and higher color rendering. As has been widely used, it has been generally a better understanding of the structure and performance of the product, supporting product technology is very mature, large-area use.

Shortcoming
Current energy-saving lamps are more energy than T8 lamps, especially spiral fluorescent lamp. Now T5 electronic energy-saving lamp than traditional T8 lamps saving 40%, combined with T8 tube halogen powder and liquid mercury mixture corrupted after recovery value, serious pollution of the environment.

 
The environmental problems caused by the T8 lamps
In fact not only T8 lamps, all the fluorescent tubes contain mercury, harmful to the human body. Casually discarded fluorescent tube causes environmental damage, in the disposal of fluorescent tubes become a problem. Only some countries and regions (for example: South Korea, Brazil, China and Taiwan) in a discarded fluorescent tubes implementation of recycling, and safely dispose of fluorescent tubes. Use only the mercury vapor in the fluorescent tube, the actual mercury content is very low (less than 1mg) and recovered when the first pumping also resulted in the recovery of the degree of difficulty. The increasing popularity of solid-state mercury fluorescent tubes can alleviate this difficulty.
