Includes three of our high-efficiency, high-power 4-foot 80-watt Commercial Quality LED Grow Lights optimized for indoor produce production with Garden Towers® and other vertical or horizontal growing platforms.
Includes: (3) Commercial Quality 4' 80-watt LED Grow Lights, (3) LED Grow Light Stands USA-Steel Black Vertical Stands, (3) Cords, (3) Sets of mounting hardware, and (1) Outlet Timer and 3-Way adapter designed for the Garden Tower® 2: 50-Plant Composting Container Garden
Easily and quickly grow organic greens, herbs, and vegetables year-round using less electricity with our commercial quality full-spectrum grow lights.
Our ultra-efficient, high-power 4-foot LED Grow Lights are optimized for indoor produce production with Garden Towers®, and are also an excellent choice for horizontal growing applications. We have selected these specific light arrays after 3 years of LED lighting tests because of their exceptional performance and value; they are nearly twice as efficient (per watt consumed) as other LED grow lights we have tested. Our Premium Garden Tower Lighting Kit includes (3) Ultra Efficient 80w LED Grow Lights, (3) USA-Steel Heavy Duty Black Stands, (3) Sets of Hardware, (3) Cords, and a hourly timer.
This chart represents the PAR (“photosynthetically available radiation” or plant-available light output) over a 90 degree field of light dispersion measured perpendicularly to the longest axis of the grow light. As seen in the data, the output is impressively uniform averaging about 85% (144 PAR) of peak output (170 PAR) across a 90 degree field. This wide, even radiation pattern combined with the 46.5″ length of the grow light array is ideal for the Garden Tower® 2 application. The under-driven LEDs in the array boost efficiency, resulting in a very high effective PAR efficiency which creates more useful light with less power consumption (80 watts).
Q: How many 80w Grow Lights can I plug into a standard wall outlet?
A: Normal United States household wiring supports 15 amps of resistive load, this means you can run loads up to 1,650 watts continuously. That equals (20) 80 watt Garden Tower® Grow Lights. However, we recommend a maximum of 16 Grow Lights per circuit to provide a greater margin of safety (1,280 watts).
For maximum growth per watt of electricity consumed, three (3) 80 watt Garden Tower® Grow Lights is optimal. For higher rates of production at a higher cost of energy, four (4) lights can be used effectively.
Q: Why should I buy more expensive LED Grow Lights instead of common florescent fixtures?
A: Several reasons:
Q: Why are these lights superior to other LED Grow Lights on the market?
We've listed a lot of information above, but the main reasons we are selling this fixture with these specifications are:
Q: How much does it costs to run these grow lights?
A: These grow lights use 77 watts of electricity on average. To calculate energy costs for a day of operation, just use the formula:
(0.077 kilowatts) x (12 hours) x ($0.15 KWh) x (1 light) =
$0.14 per day per grow light
or $0.42 per day for a set of 3 grow lights
Just adjust the formula for differences in photoperiod (length of light use use per day), differences in cost of electricity, or differences in the number of grow lights.
Q: How many hours per day should grow lights be on?
A: The day length or number of hours of light per day used by plants is called the photoperiod. Different plants are sensitive to different photoperiods. Some plants move towards a flowering stage of their life cycle based on short or long photoperiods, and others are neutral and flower based primarily due to other factors such as light spectrum or color. For vegetative growth crops (lettuces, most herbs, other greens), your goal it to keep them in a vegetative state of growth for the fastest and largest production before bolting.
In very general terms, this can be usually be accomplished by not exceeding a photoperiod of 16 hours which provides 8 hours of rest for the plants. Most plants need a minimum of 6 hours of darkness or their health will be negatively impacted. We suggest a few minutes of web research on the plants you plan to grow with the term “photoperiod” to find specific information for optimizing the performance of your indoor grow! Eventually we will put together an infographic with more information here on our site.
