Introducing the new GLM 660 from Rayonled!


This LED grow light is the latest products from Rayonled's team of lighting bioengineers. Backed by their impressive expertise in LED technology, this medical-grade unit has everything to appeal to both hobby and commercial growers.

Looking to bring you garden to the next level? Look no further. The GLM 660 is designed to replace and surpass the results from a 1000W HID fixture. From the spectrum to the certifications, it has been thoughtfully crafted to compete with the top grow light on the market.


Key features:

- Designed and assembled by Rayonled in Canada.

- Passively cooled bars provide full-spectrum, broad-coverage light for full-term growth

- High-output 1872 µmols PAR! and an impressive efficacy of 3.1 µmol/s per watt

- IP65 certification allowing the light to perform and last even in the most humid grow rooms

- Independent bars and driver ensure that even if a problem occurs the light can be repaired without losing the production of the entire fixture.

- Best-in-class durability testing. Instead of doing a regular 48h test on their lights Rayonled will test every fixture in a special oven that provides the highest standard of heat resistance.

- 5-year full warranty on all fixtures.
