True Full Spectrum LED Grow Light

Look no further than Tall Trees LED for True Full Spectrum LED Grow Lights for any solution and budget. All of our grow lights feature our True Full Spectrum white LEDs engineered for optimal plant growth.

Where Everything Began

The Tree Master Mini 28W 6th Generation LED Grow Light (Formerly Super Grow LED SGL6) is the culmination of over 14 years of study, testing and manufacturing of frequency-specific lighting technologies. Ideal for seedlings, clones, early vegetative growth stages and small plants where IP65 rating is needed.

Not Your Standard White LEDs

The TMM28 features Tall Trees LED’s Scientifically Engineered Spectrum IIe True Full-Spectrum White LEDs. Our white LED is the World’s Most Advanced Horticultural White LED. Manufactured only for Tall Trees LED, we start out with Premium Bin High-Power 425nm Blue Base 3W LEDs and then coat them with our Proprietary Phosphor Formula giving our lights the fullest spectrum available from ANY grow light ANYWHERE.  Learn More About Spectrum IIe

Deep Reds For High Yields

Alongside our Advanced White LEDs we also supplement with Premium High-Power 660nm Deep Red 3W LEDs for precision saturation at the plant’s Chlorophyll-A peaks which are critical for maximum fruit and flower production. During heavy fruiting and flowering, plants may use as many as 10x more red photons as blue photons used during vegetative growth making saturation at this frequency extremely important for all gardens.

Light Your Crop, Not Your Room

At Tall Trees LED, we strive to put as many photons on canopy as possible with all of our grow lights. We achieve this by using Precision Total Internal Reflective (TIR) Lenses on all of our commercial products. These lenses collect up to 94% of the photon output of the LEDs and refract and focus it predictably and uniformly across your crop’s canopy. This helps prevent photons from being wasted on walls and other non-photosynthetically active surfaces.

Moving Parts Fail, Your Grow Light Shouldn’t

The number 1 killer of LEDs is heat and it builds up when FANS FAIL. We overbuild all of our commercial product’s cooling systems by 30%+ using Passive Heatsink Cooling Technology. No Moving Parts To Fail, Ever! Our heatsinks pull waste heat away from the LED chip’s slug and dissipate it directly into the grow environment providing SILENT, rock solid performance and reliability.

Power Your Light Anywhere

No matter where you are in the world, your TMM28 will work. It is equipped with a Precision Constant Current Power Supply featuring Under/Over Voltage Protection and Under/Over Current Protection. Capable of handling 100VAC-240VAC for all residential and commercial power sources world-wide.

Built To Outlast

All of our commercial products are built using premium materials and rugged designs. The TMM28 is IP65 rated and built using 6000 series aluminum and tempered glass to handle anything your environment can throw at it. With an expected lifespan of 60,000 hours, we also include the best warranty in the business – 3-Years, No Hassle Warranty.
