User Manual



This is the Flex Star 645 Watt professional Horticulture grow light. This folding light comes preassembled. It has a really large footprint, its dimension is 127.34cm x 110.76cm. You have the option of attaching the drivers directly on top of the LED bars with rubberized plastic mounting clips or you can keep the driver outside your tent if you prefer.

The LEDs are spread out over six individual bars, which passively cool the PCBs through an anodized aluminium rear plate. The six bars are configured in a foldable design. This allows easy transport and the LEDs themselves are Samsung 5630 3000K warm white and 6500k cool white LEDs and in between those are space as round 3535, 660-nanometer red Led diodes. This gives a light of full-spectrum coverage and makes it ideal for pretty much any type of growing situation. The driver is Flex Stars own and it's dimmable, so the dimmable function goes from 40%, 50%, 60%, 80% or 100%.

  1. Quality

    By Kimbo February 21, 2021

    This is a bit over kill for a home setup however it does produce top shelf quality. Before this I ran cod leds and quantum boards which are prone to bleaching tops. This light gives more par without bleaching.
