13 8 units previously used as demos at shows or for only 1 grow cycle (3-4 months). Each unit has been tested and meets the same standards as our new units. We back these units with a full 5-Year warranty from date of purchase. Each is deeply discounted to $750 with a flat shipping cost (FedEx Home Service) of $68 within the Continental United States ($818 total). For shipping to Alaska or Hawaii, please call or email for rates. Once these are gone, they are GONE. Due to high demand, we don’t get to do this very often, so act quickly!
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.
Ideal for all stages of growth including propagation, vegetative, fruiting and flowering. Our new Harvest series uses all the same advanced technologies from our Tree Master series and adds additional functions and features in a new lighter and sleeker modular design.
The HU600 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.

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.
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. Available with either 90 degree or 45 degree precision lenses to suite the plant, garden and grower’s preferred coverage, intensity and penetration.
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.
“If there are two or more ways to do something, and one of those ways can result in a catastrophe, then someone will do it.” -Edward A. Murphy, Jr. (Murphy’s Law)
Things do break and accidents do happen. The entire Harvest series has been designed to be end-user serviceable allowing you to replace components your self in the event of a failure. All connections between Light Engine Modules (LEMs) and Power Supply Units (PSUs) use IP65 quick connect fittings. No need to ship back for repairs.
No matter where you are in the world, your HU600 will work. It is equipped with 2 Precision Constant Current Power Supplies featuring Under/Over Voltage Protection and Under/Over Current Protection. Capable of handling 100VAC-277VAC for all residential and commercial power sources world-wide.
Unique to the Harvest Ultra is the 50%/100% Dimming Switch. This allows users to reduce the light intensity to 50% (240W) during vegetative growth stages when lower levels of light maybe required. Best of all when dimmed there is NO SPECTRAL SHIFT and no change in coverage. Learn More About Spectral Shift
All of our commercial products are built using premium materials and rugged designs. The HU600 is IP65 rated and built using 6063 Aluminum and Stainless Hardware 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 – 5-Years, No Hassle Warranty.
