Indoor 300W COB LED grow light to replace apollo led grow lights

4. Over-temperature self protection function. In case of an HVAC malfunction,fan stopping working or other, when a sensor in the unit reads a temperature of over 70 degrees Celsius the machine will intelligently turn itself off. When the unit cools down it will automatically turn itself back on.

6. Aluminum casting. ultra light weight. only 5.5kg. 

Some introduction about lighting physiological functions:

Far red light

The far red intensity and R/FR are important for photomorphogenesis such as plant height,internode.When the value of R/FR is higher,the internodal length becomes lower,resulting in plant dwarf.The ratio change is also related to axillary dud differentiation,chlorophyll content,stomatal index and lead area.Far red light decreases 40% anthocyanin,11% carotenoid and 14% chlorophyll,increasing 28% fresh weight,15% dry weight,14% stem length,44% leaf length and 15% leaf width.

UV light

The light with wavelength below 380nm is called UV light.The band 320~380nm is for UV-A,280~320nm for UV-B and 100~280nm for UV-C.95% UV reaching the ground is UV-A.UV and far infrared keep the regulation for the growth.UV light reduces leaf area,inhibits hypocotyls elongation,weakens photosynthesis and makes plant easier to be attacked by pathogen.However,it induces flavonoid.What’s more,low UV-B environment plant experiences excessive growth and pigment synthesis disorder.Plant factory lacks UV-A and UV-B.To keep a balanced UV dosage is helpful for plant growth there.
