R&D and Service
1) Developed highest watts 150W for full spiral models, size only 125*325mm, work under minus 30°to 80°.

2) Use 14 mm tube to replace 17mm tube from 65w to 105w, 12mm tube to replace 14mm tube from 45w to 65w, dropped cost greatly.

3) Luminous Efficacy of A60 reach 65lm/W, energy grade A.

4) Drop the defect rate greatly under voltage fluctuation environment.
