Our current talk  topic is photosynthesis of plants with plants lamp.
we all know that photosynthesis is the process that enables plants to live and grow.
the light wave is most fundamental condition for Photosynthesis.the length wave between 400nm ~ 720nm.400 ~ 520nm(blue light)and 610 ~ 720nm（red light). red light and blue light top contributor for photosynthesis. Actually the plants don’t green light so The 520 ~ 610nm（green light）of radiant energy absorbed by the photosynthetic has been small.

While there are have lots device suitable to be used in plant grow. they include :Pressure sodium lamp, metal halide lamp, ceramic metal halide lamp, microwave sulfur lamp, Plasma lamp, fluorescent lamp, electrodeless lamp and three color lights, LED light rare earth plant etc. Sodium lamp, metal halide lamp and LED lamp plant are is most commonly used.
