1. The inner wall of the lamp adopts the rare earth tricolor luminescent body as the luminescent material. Compared with the ordinary lamp with the traditional calcium phosphate as the luminescent material, the luminous efficiency is increased by 35%, the color tolerance is small, and the color development index Ra is as high as above 85, which makes the illuminated objects more distinct, more colorful, more realistic, and more comfortable for the eyes.

2.Advanced water coating technology, low light decay, high lumen maintenance rate, life of more than 12,000 hours

3. There are sunlight color, cold white, warm white different spectrum options, can adapt to different environmental color temperature requirements.
4. Add cathodic protection ring at both ends of the lamp to prevent blackening at both ends.
5. The main and auxiliary triple helix filament ensures sufficient electronic powder and long service life.
6. Widely used in factories, hotels, upscale business districts, office buildings, schools, exhibition halls, libraries, laboratories, etc.
