Why to Make Greenhouse Grow Light a Linear One?

People always have questions about a professional greenhouse grow light, such as why so expensive compared with a indoor one? Why to make it a single linear light? Why to make it so heavy?......

The major reason is that too many dilemmas exit for a greenhouse grow light -- large scale commercial plant requires for high power for high PPFD to assure the yield; the light shoud be as narrow as possible so that not to block natural sunshine from the sun; high power means more heat emitting by the fixture, which requires bigger luminaire size by quality and strong materials adoption for heat dissipation; strong materials adopted leads to heavy weight, which is a challenge to the reliable installation and becomes a limitation for high power again; the heat dissipation from the grow light itselt is a big challenge to the crops plant......    

If to figure out one focal factor to decide the greenhouse grow light design, which differentiate it obviously from the indoor grow light is Heat Dissipation. The greenhouse needs a good balance between temperature, CO2 and humidity in a closed atmosphere by good heat control, but the light emits heat a lot; what's worse, the more heat the higher power; but on the other side, to assure good PPFD on the crops for light supplimental, high power is a must; what's worse, high power fixture always leads to heavy weight, which is a big challenge to safety of the greenhouse structural framwork.

Upon deep research and the universally on field plants, 630W by proper structure design works the best for greenhouse plant for light supplimental purpose by perfect balance among various factors in dilemma. 

Privately designed smart control system always goes perfectly with grow lighting products.
