We are manufacturer, we have below advantages:
1. We have a capable developing team, there are 15 electric engineers, mechanical engineers and certification engineers. We handling from independently program developing until producing and shipping.
2. Electrical engineering institute of Zhejiang University, which is a classic electric lighting research institution in China, supports us developing technology. It is also renowned abroad, and ever cooperated with GE Lighting, Philips Lighting, Universal Lighting etc.

3. Our ballasts are with excellent circuit design and structure design, and with standard authentication. We have our own test standard and process by particular QC. He test strictly and analyse results.
To make high quality ballasts, we fully considered the matched lamp and make all protection function, especially for starting and open loop, short loop as well as over tempreture and output power limit.
4. Our Waho Holding Group produce electric products since more than 20 years ago, we are experienced in mass producing and managment and quality control.
