 Advantage for GLMX240

Specifically designed for seedlings:

This 240W special lamp for cannabis seedlings has been customized. It combines low power output with precisely adjusted PPFD, adding white light and 660nm deep red light to fully take care of the lighting needs of cannabis seedlings. Its efficient heat dissipation ensures an ideal temperature. Control to provide the most suitable growth conditions for seedlings.

Using top-grade white light LED:

Samsung white LEDs are used to continuously and evenly cover the PAR400-700nm growth spectrum.

Equipped with high light efficiency deep red LED:

It uses high-efficiency 660nm red LED to provide plants with an efficient deep red spectrum and promote plant growth.

Excellent cooling performance:

The heat dissipation area of the entire lamp is as high as 4593144 mm²/7199 in². The thermal conductivity of the radiator reaches 201-218 W/(mK), ensuring that the average temperature of the LED grow light remains below 50℃/122℉, with a longer service life and more efficiency.

IP65 waterproof design:

The light source of the lamp adopts a high-quality waterproof design, so that it can work stably even in high-humidity environments.

Full Spectrum for VEG & BLOOM

GLMX series full spectrum LED grow lights use some of the best horticulture LED diodes on the market from the top suppliers. In order to enhance the power output of of the area plants need the most, we have used much more Red and Blue high power LED diodes than most competitors on the market. At the same time, the overall spectrum balanced with all colors mixed make sure the plants receive all the wavelength to grow faster and stronger, as well as yield much more flower. FSCV with high power in blue is intended to grow plants in a more compact way which is essential for vertical farming with limited vertical space, while FSCH with fewer blue and enhanced power in red and infrared is ideal for growing plants in a traditional indoor single-level grow room with more vertical space for plants to grow bigger and yield more flowers.

This light has extruded aluminum bars that feel and use samsung diodes like the higher priced lights. It's dimmable and linkable. The efficacy is right there with the best of the best at 2.75 umols. It's really amazing how much the prices have come down on a bar style light like thi
Sasha happyfox
Light easily assembled in minutes. Seems well built. The driver does get relatively hot so I recomend a small fan pointed in that direction. Very bright and has a great footprint,
Crazy Craze
These are great lights I did a DIY grow light stand and used these lights. It was so easy to install and put together. I would recommend to family and friends.
