Why Full Spectrum LED Grow Lights?:

Why Your Plants Need Full Spectrum LED Light?
The key benefit of our LED grow light is its remarkable ability to mimic natural sunlight by emitting a full spectrum of light. Red and blue light wavelengths activate photosynthesis, but are not the only wavelengths plants need. Oversaturating your plants with only red and blue wavelengths actually causes them to go dormant, leading to under produced plants.

By using LED Light with full spectrum, which appears as white light, it induces your plants to undergo natural photorespiration. While that will force them to work harder, it also leads more efficient nutrient intake. You end up with sturdier plants, healthier growth, and increased yields.

Increased Efficiency:

Aside from emitting a full spectrum of light, this LED Grow Light affects your bottom line. While it offers the same intensity as a dual-ended 1000-watt HPS bulb, our 640W LED grow light uses only a fraction of electricity while emitting only about 1550 BTUs of heat. That all equates to big energy savings of over 60% as compared to dual-ended 1000 Watt HPS bulbs in energy costs and a light that produces less heat than most of the competitors. Those energy savings equate to lower utility bills since your HVAC appliances are used less to combat the high temps common with HPS rooms. A typical return on investment is less than a year for small grows and up to 18 months for commercial grow operations.


Our LED Grow Lights are recognized by the international standard that designates products fit for use in wet and humid conditions. Very few companies that make grow lights qualify for this certification which is why we designed our lights with IP65 ratings in mind as most indoor gardens and commercial greenhouses have wet and humid environments creating challenges for gardeners. Our IP65 housings make clean up easy and you can foliar spray your canopies without worrying about damage to the lights internal components.

Install Guide:

How To Hang Our LED Grow Lights
Correctly hanging grow lights ensures proper coverage and safety. Fortunately, we make it simple to do. Your standard rope ratchet rated at 40 lbs. will easily hold your lights, which weigh 7 to 26 lbs. depending upon the model and options chosen.

Please note that most rope ratchets have carabiners too small to fit our lights, which is why we recommend using the attached “S” hook as it makes it so much easier to hang the light. You can use the additional bracket to hang the light at an angle of your choice from a fixed position or take it off and use the center ring to hang the light.

Placement of Lights
Lighting fixtures work best when shared. By placing lights in close proximity to each other, plants that would otherwise be on the periphery receive more light from both lamps, thereby increasing their productivity in what is known as cross illumination. Please review the footprint that works best for your application of light.

Coverage Areas
Raising the light higher above your plants increases the light coverage, but also decreases the light intensity. Therefore, it is important that you find the appropriate balance between intensity and coverage. Each LED One widely used method to determine a lamp’s intensity over time is the Inverse Square Law. As a general rule of thumb these results can be found in most lighting scenarios and is only being used here as a guideline. Using different reflectors that focus light into a narrow region such as our 90* reflector will change the outcome of these values greatly as will our 120 reflector.

Once your lamp is properly secured to the ceiling, you must determine the appropriate hanging height above your plant canopy. Light intensity diminishes at an exponential rate; therefore, the closer you hang your light, the greater its effect will be. With LEDs, plants can touch the lamp without suffering heat damage to the plant. However, the light is too intense for most plants to be any closer than 24” of our light source* grow light has a been rated to cover a determined area.

120° reflector: 5’ x 5’ at 24-30” above the canopy during flower for normal plants and should be placed up to 36” above the canopy for sensitive strains. For vegetative plants, it can cover up to an 8’ x 8” area at 4’ above the canopy.
