Typically LED grow lights come in three shapes:
Tubes, bars and box lights. Tubes are low intensity,
negligible heat luminaries often used as retrofit for T8 fluorescent tubes.
Tissue culture and vertical farming are the most common applications.
Bars vary in intensity greatly and are thus most versatile,
ranging in applications from multi-tier cultivation to greenhouses
where they hang high and cover a large area of crop.
Box lights are typically high intensity lights and are thus used in greenhouses,
sometimes as HID replacements.
Fusion8910-PG is more compact, greater energy efficiency than those conventional luminaries.
It is also simple and flexible installation than other one.
