Abstract

A LED tube luminaire for growing plants in greenhouse and indoor horticulture comprising individual LEDs on a substrate with higher linear density, no focusing optics on LED, a glass tube, the end cups, electronics, and electrical contactors. The LED tube luminaire has high light intensity, random direction white light with different color temperature for grow and bloom. An LED grow light has a substrate mounted within a glass tube. A linear array of LED chips is mounted on the substrate and aligned in a single line and comprising a plurality of LED chips. The plurality of LED chips has a regular spacing of less than 15 mm on center. The linear array of LED chips has a single color temperature having greater than 80 color rendering index. A pair of terminals mounted on ends of the glass tube. The pair of terminals are not symmetrical.
