Horticulture Lighting Group HLG 100 LED Grow Light Review


HLG 100 Build

The Horticulture Lighting Group HLG 100 LED Grow Light is the big brother of the HLG 65. Instead of drawing 65W like the HLG 65, it draws right around 100W from the wall. The fixture measures 32.5cm x 28cm and weighs less than 3 lbs.

A large Meanwell is screwed to the top of the light and powers the PCB beneath it.

The fixture designed to replace a 200W T5, 250W CFL, or 200W metal halide/HPS grow light.


Diodes on the HLG 100

There HLG 100 uses 192 top-bin Samsung LM561C S6 diodes.The PAR efficacy of the unit is around 2.3 μmol/J. The PPF output is measured at 225 umol/s.


HLG 100 Wattage Draw

The Horticulture Lighting Group HLG 100 draws 96W at the wall. The driver is rated for 100 to 240 VAC. If used in another country, it will need a plug adapter since it comes with a US 3-prong power cord.


Spectrum of the HLG 100

The HLG 100spectrum is full-spectrum white, and is available in 3000K or 4000K. 3000K is best for flowering, while 4000K is best for veg. If you are using this light for a full cycle grow, we suggest the 3000K version for the best yields, but some growers prefer 4000K if they want to focus on quality over yields.


HLG 100 Coverage Area And Hanging Height

Hanging height varies on application. For supplemental light, you may want to hang this fixture at 18” to 36”. When used as a primary fixture, you can hang it as low as 12” for the highest intensity. The recommended flower footprint of the light is 3 to 4 square feet, while the veg footprint is around 6 to 9 square feet. This light only uses 100W so even at the very best efficiencies, you will not be maxing out the PAR values that your plants can accept. in the given coverage areas, you will have a medium to low-intensity flower and veg.
