Passive cooling green house IP67 waterproof no fans LED linear grow bar high PAR value 600W

With the world-wide legalization of cannabis cultivation for medical and recreational use, in order to achieve the best state-of-art yield in terms of both quantity and quality, indoor cultivation has been widely adopted by professional growers. it produce more compact buds but also more organic quality within indoor cultivation . LED grow light has high electrical efficiency, long life span, and relatively broad spectrum provided growers the best option in lighting.

CGEING green house water-proof linear light bars series is die-casting case design, it generates less heat, dramatically reducing ambient temperature, saving the electricity cost in cooling system within green house and other growing facilities. The fixture is with unique fin aluminum heat sinks cross-ventilation cooling system ,it is the guarantee of sufficient heat dissipation, generating less heat and reduces ambient temperature. Moreover, this passive heat dissipation design avoids fan’s noise, it also contributes to the stable performance of the whole LED grow light by eliminating the moving parts(fans), providing an easy maintenance for growers.

5. What is PPF/W and why PPF/W becomes µmol/J?
PPF/W is the measurement of photon efficacy.
Photon efficacy measures how much energy is used by the fixture to make the light that ranges from 400nm-700nm. It tells how efficient a grow light at converting electrical energy into photons that useful for plants.
The unit for PPF is μmol/s, and the unit to measure watts is Joule per second (J/s), therefore, the seconds in the numerator and denominator cancel out, and the unit becomes µmol/J.

6. What are the different bettwen HPS and LED?
a. HPS turns 80% of the energy into heat and only 20% into light, while LED grow light turns 80% of the energy into useful light to plants. Therefore, LED grow light is saving cost in ventilation and in air conditioning.

b. The lifespan of LED grow light is around 50,000 hours while HPS only runs about 10,000
hours. Therefore, growers have to replace new HPS lights every 2 years,this makes another advantage of LED grow lights.

c. Taking the energy efficiency,heat dissipation and lifespan into account, growers can get their initial investment on LED grow lights back within 2-3 years. The overall reviews from many growers also prove that switching HPS to LED grow lights is a worthy investment for a long-term cultivation planning.

Why should order LED grow lights from GBEING, a Chinese manufacturer?

Thanks to the technological developments, almost all business nowadays are available online. You may hear lots about bulk goods importing from China but rare will buy only one or two because a certain MOQ is set by most of the Chinese manufacturers in practical. Taking the complex import procedures into account, most buyers would just say "forget it".
