Raw materials for electrodeless lamp is one of the reasons. phosphors is one of the keys to the selection of electrodeless lamp. Firstly, Photosynthetic efficiency of halogen powder generally between 50-60, and pure trichromatic phosphors can fully insure above 80. If mixed halide powder, then the light efficiency is reduced. Secondly, powder halogen`s light attenuation time can only be valid for one year, while pure trichromatic phosphors` photosynthetic efficiency of more than 70 can be valid within three years. But due to the current technical condition is limited, it`s hard for customers to distinguish whether it is pure trichromatic phosphors or mixed with halogen powder. That`s why customers need to choose manufacturer carefully. XPES induction lamp adopted pure trichromatic phosphors, the current market price is 3000 / kg, if it is mixed with halogen powder, the price would be much more lower. 8 years experience in electrodeless lamps engineering, we only manufacturer the best quality induction lamp. XPES is the first choice of induction lamp manufacturer. From: Guangdong Xingpu Energy-saving Light CO., LTD Website: www.chinaxpes.com
