Mars Pro II series:None lens diodes,higher light intensity
Light usually emit intense lights equally in all directions-360 degree,especially LED grow light,lights can not go directly to the place we want them arrive.The idea of cup-shaped lens can be designed to focus the light coming from the emitter anywhere from 30° to 180°.
Although the cup-shaped lens was excellent for adjusting the angle of the light, the light tended to be attenuated in the lens, resulting in a loss of the light generated by the light emitting diode.
Also the heat will accumulated in side the lens,if will speed up the light-fade.
Mars Pro II series lights solved these problems by installing the light without lens.
With the reflective cup,the reflective cup collect 100% lights which emitted from the diodes,and the light will be 100%reflected back to the plants.No heat will remain inside of the lens,it will slow down the speed of light-fade.
This design is better for mixing REFLECTOR spectrum and exporting 100% LUMEN as well,with higher light intensity.
