For Growers!


Do LED grow lights increase yield?

Yes! Proper lighting ensures plants are getting the most beneficial PPFD at each growing stage, thereby enabling accelerated and more efficient photosynthesis.

How does LED light increase plant yields?

Intense, specific wavelengths can be tuned to excite photosystems that are the drivers of photosynthesis. The proper light can induce greater rates of photosynthesis with less energy consumption than traditional lighting sources.

How far do LED lights penetrate the canopy?

Many factors work to determining how much light penetrates the plant canopy.  Plant species, leaf thickness, leaf size and the number of leaves within a given area all play a part in light penetration, and so it’s impossible to make a blanket statement. We can say that the quality of our INNOV44 LED grow lights deliver to the plant encourages increased leaf accumulation to intercept more light and increase production further.

How is Photosynthetically Active Radiation measured?

Photosynthetically Active Radiation (PAR) is reported as millimoles of light energy per square meter

What is PPF/Watt?

PPF/Watt is a measure of fixture efficacy, expressed in micromoles per joule; this metric represents the total number of photons in the photosynthetically active range of wavelengths generated by one joule of electrical energy. This is an electrical efficiency metric that is referenced, instead of lumens per watt, for horticultural LED lights.

Why do plants need special horticulture LED lights?

To accomplish photosynthesis, plants need light from different places on the visible light spectrum (400nm to 700nm). Plants mostly use red light and blue light for proper vegetative growth and flowering. And humans who need to see the plants appreciate a little light in the green part of the spectrum, which is where we see best. So the best LED grow lights are those that combine, in the proper proportions, light from these three parts of the spectrum. With LEDs, we are able o provide only the usable spectra and wavelengths without wasting energy on those that are not beneficial to plants.

Average Rated Life

An average rating, in hours, indicating when a percentage of a large group of lamps have failed, when operated at nominal lamp voltage and current. The life of an LED is defined as the operating time in hours for the lamp to reach L70 which designates 70% lumen maintenance (or 30% reduction in initial light output). Every lamp type has a unique mortality curve that depicts its average rated life.


A two-terminal semiconductor device having a p-n (positive-negative) junction which allows energy travel in one direction.


A self-contained power supply that has outputs which match the electrical characteristics of the lamp. It is similar to a ballast and is used to power illumination sources.

Heat Sink

A heat sink is an environment or object that absorbs and dissipates heat from another object. The design of an LED retrofit lamp’s heat sink is an integral factor in the overall performance of the lamp.

How are LEDs made?

LEDs are made from very thin layers of semiconductor material; one layer will have an excess of electrons (the n-layer), while the next will have a deficit of electrons (the p-layer). This difference causes electrons to move from one layer to another, thereby generating light. The process of making LEDs is very intricate, with hundreds of steps.

How do LEDs help the environment?

LED technology offers many environmental benefits. The production and use of LEDs requires significantly less energy than incandescents or CFLs. With INNOV44 LED Lighting products, there are no lamps to throw away and the entire fixture is recyclable with no mercury content to worry about. All INNOV44 LED Lighting products are free of mercury and other toxic materials, a clear win for the environment.

How long do LEDs last?

Unlike other light sources, LEDs don’t suddenly “burn out;” instead, the diodes gradually produce lower light levels over time. LED useful life is generally based on the number of operating hours until the LED is emitting 70% of its initial light output (known as L70). All of INNOV44 LED ligths are rated to at least 50,000 hours in a 25° C ambient environment, with some fixtures offering much longer lifespans and even higher ambient temperature environments. LED light output and useful life are strongly affected by elevated temperature due to improper design of the thermal management system.

While incandescent and fluorescent lighting will fail sooner when switched on and off often, LED lighting is unaffected by how often it is turned on and off.
