Battle of the Grow Lights: HLG 650r vs 550r

 

Horticulture Lighting Group (HLG) has been a leader in the field of horticultural lighting for decades. Their high-density modular light engine, which is used in their grow lights, is revolutionary and has made them a top choice for growers who want to get more out of their plants.

HLG 650r and 550r are grow lights that use the HLG high-density modular light engine and are perfect for the professional grower. These lights are capable of producing a remarkable amount of light, yet are energy efficient and easy to install. They are also easy to use and control, making them a reliable choice for growers who want to maximize their yields without having to hassle with their lights.

But how do they differ from each other?

Full-cycle plant growth is supported by the HLG 650R, a 630-watt LED grow light. Newer, more powerful Samsung LM301H LEDs are used in this grow light. Meanwhile, the HLG 550r, on the other hand, is a huge, white-spectrum, modern-designed LED grow light that can adequately illuminate a 4' by 4' area.

The HLG 650r Samsung LM301H LEDs are designed to illuminate plants with a spectrum of 4000K. This spectrum is designed to enhance both blue and red wavelengths, making it excellent for full-cycle cannabis plant growth.

The HLG 550r comes in a 3500K spectrum. However, the HLG 550r diodes only emit some additional blue light—which is absorbed primarily by vegetation but also by flowering plants—along with extra red intensity, which aids rapid growth of your plants. So in terms of spectrum and intensity, the HLG 650r is a great option for any grower who wants to produce high-quality flowers in an efficient amount of time.

Regarding their flowering footprint coverage area, the HLG 650r can cover 5' x 5' at 30' while the HLG 550r covers 4' x 5' at 24'. For vegetative footprint, the HLG 550r covers 6' x 6' at 36” while the HLG 650r can cover 7' x 7' at 48”. So if you have a larger grow space, then the HLG 650r clearly is your best bet.

Down to its other features, both are passive cooling and have a 5-year warranty. Regarding their build quality and design, the HLG 650r is slightly larger than the 550r and has a higher PAR output with better coverage area.

Overall, their build quality is top-notch and both lights are great for indoor growing.
