Guangmai Technology is proffesional in making the 1 Watt Red Power LED Chip 620nm 630nm.
630nm and 660nm led application: Red therapy LED Light
Product Features:
• 99.99% gold wire bonding
• High flux per LED
• More energy efficient than incandescent and most halogen lamps
• Instant light(less than 100ns)
The red light therapy instrument is a new type of phototherapy equipment that can be used in hospitals and homes. Its basic principle is to obtain a red visible light band mainly from 600 to 700 nm through a special filter. This band penetrates the human body deeply and has a better curative effect. it is good. The whole machine has high output power (equivalent to more than one hundred times that of He-Ne laser) and large spot (equivalent to hundreds of times that of He-Ne laser), providing a better treatment method for treating some large-area diseases. The light output is divided into "strong" and "weak" grades to adapt to patients of different physiques. The whole machine adopts a movable floor-standing cabinet design, and the red light lamp holder can also be raised and lowered steadily by electric power, which is the manual red light and automatic red light on the market, which greatly facilitates medical workers.

We promise all our led chip are 100% power enough,some seller sell only 50%-70% power.
Our LED chip will work more than 50000hours if the working temperature is less than 60 Degree,so they need to work with heatsinks.
