Greenhouses that use LED lighting vs. HPS see tremendous energy savings.
Our products are ETL listed. The ETL Listed Mark is an alternative to UL listed marks. Like UL, ETL “demonstrates compliance to the requirements of widely accepted product safety standards” and both are accredited by the Nationally Recognized Testing Laboratory (which is part of OSHA) to test to these standards. In passing ETL tests, Illumitex products are certified to meet rigorous standards for electrical safety and electromagnetic emissions.
ETL Testing Laboratories has been conducting electrical performance and reliability tests since 1896. Intertek Testing Services (ITS) acquired ETL from Inchcape in 1996. ITS is recognized by OSHA as a Nationally Recognized Testing Laboratory (NRTL), just as Underwriters Laboratories (UL), Canadian Standards Association (CSA) and several other independent organizations are recognized.
ITS tests products according to nearly 200 safety and performance standards. The ETL Listed Mark and C-ETL Listed Mark are accepted throughout the United States and Canada when denoting compliance with nationally recognized standards such as ANSI, IEC, UL, and CSA.
This certification mark indicates that the product has been tested to and has met the minimum requirements of a widely recognized (consensus) U.S. product safety standard, that the manufacturing site has been audited, and that the applicant has agreed to a program of periodic factory follow-up inspections to verify continued conformance.
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.

Absolutely. When horticultural LEDs first emerged into the cannabis market, the technology was just beginning to be explored, and a lack of information lead to some early assumptions and practices. Since then, many successful growers have proven that LED grow lights work very effectively as sole-source lighting for cannabis.
Almost all Illumitex LEDs are IP66 rated, meaning they are dust-tight and water-tight at the LED package level. Because they can be washed down along with everything else in a food-processing environment, they are safe and efficient additions to this type of setting. In an indoor growing situation, Illumitex IP66 rated LED horticulture lights are equally safe from irrigation dampness.
Refers to the luminous intensity at the center of the beam of a blown or pressed reflector lamp (such as a PAR lamp). Measured in candelas.
Circadian resonance applies to a match between a plant’s circadian rhythms and the light-dark cycle of the environment.
Circadian rhythm is a biological activity that shows a cycle of high activity and low activity independent of external stimuli, with a regular periodicity of about 24 hours.
Critical day length is the minimum length of the day required for flowering of long-day plant — the maximum length of the day that will allow short-day plants to flower. However, studies have shown that it is the length of the night, not the length of the day, that is important.
Critical night length is the night length that must be exceeded for flowering of short-day plants, or for inhibition of flowering in long-day plants.
Cryptochrome 1 a flavoprotein involved in the inhibition of stem elongation and other blue-light responses.
Daily light integral (DLI) measures the number of photons that fall on the plant canopy over a 24-hour period. DLI has a profound impact on plant growth and development for essentially all greenhouse crops.
A two-terminal semiconductor device having a p-n (positive-negative) junction which allows energy travel in one direction.
No. UV light can stress cannabis plants, and the plants respond to this stress by increasing production of trichomes, which is a desirable result for many growers. However, there are other ways to induce stress in cannabis plants that don't waste watts.
- Drop nighttime temperatures in your grow room to make plants think winter is approaching; they’ll go into overdrive and produce more trichomes.
- Conversely, induce stress by raising temperatures; use caution, though, as heat stress can form elongated, wispy flowers.
- Lower humidity to 15% at the end of flowering cycle.
- Decrease photoperiod or even turn lights off for 2-3 days prior to harvest.
- Use ice water for final flushing of plants.
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.
We sure do. Please read our limited warranty.
illumitex offers a 5-year limited warranty on our LED light fixtures to the original purchaser with a valid receipt.
Illumitex products absolutely work in cold environments. Illumitex LED luminaires are the perfect solution for a broad range of industrial applications, including cold storage, freezer and cold food processing. While fluorescent and other technologies can be adversely affected by cold temperatures, this is not an issue with LED lights. LEDs love the cold.
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.
A footcandle is one lumen per square foot. The 16th General Conference on Weights an Measures (CGPM), Oct. 1979, decided that the candela is the luminous intensity of a source emitting monochromatic radiation of frequency 540 x 1012 Hz and radiant intensity 1/683 watt per steradian. This corresponds to 683 lumens per watt of radiation at approximately 555 nm wavelength, which is near the maximum of the standard photopic spectral luminous efficiency curve.
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.
High irradiance response are phytochrome responses whose magnitude is proportional to the irradiance (rather than fluence). HIRs saturate at fluences 100 times higher than LFRs and are not photoreversable. HIRs do not obey the law of reciprocity.
Illumitex's patented LED package technology offers perfect edge-to-edge color uniformity. Illumitex LEDs emit light directly from the die in a uniform and precise beam and our die-level optical integration means there's no need for large, inefficient secondary optics. We deliver the highest center beam candle power (CBCP) and deliver more uniform light to the intended target than any other LED and optical system on the market.
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.
Illumitex LED lighting products are sold through stocking distribution or through select hydroponic and indoor gardening centers.
LED technology offers many environmental benefits. The production and use of LEDs requires significantly less energy than incandescents or CFLs. With Illumitex LED Lighting products, there are no lamps to throw away and the entire fixture is recyclable with no mercury content to worry about. All Illumitex LED Lighting products are free of mercury and other toxic materials, a clear win for the environment.
A full evaluation of LED products requires a review of the overall system efficiency, optical control, thermal management of the LEDs, and an assessment of the point in time the fixture will reach 30 percent lumen depreciation. Products with good optical efficiency and thermal management will be able to deliver more lumens, on average, than traditional HID products as well as other, poorly designed LED lighting products. You asked a good question; it's important to thoroughly evaluate LED products before buying.
It is important to maintain healthy “mother” plants to ensure that the cuttings are also healthy.
As you prepare your healthy cuttings, it is important to provide optimal lighting conditions right away. Pay careful attention to three important lighting issues: light intensity, uniform coverage and spectrum.
Balancing light intensity is essential at the cloning stage. Providing too much light can cause the plants to deplete their resources before they develop a healthy root system. Too little light can cause stretching, which can delay growth and create weaker plants. A one-size-fits-all formula doesn’t exist because different crops and crop varieties can have different spectral quality and quantity needs. It's best to carefully observe your specific varieties and note how they react to different light levels.

Illumitex LED fixtures are designed with maximum LED diode junction temperature and proper thermal management solutions in mind. These products are robust enough to operate in typical and ambient environments. Our LED efficiency is well demonstrated.
Using LED lights can require different mounting heights as compared to HID lighting. And while it’s difficult to offer hard and fast rules for light mounting heights, we’ve come up with some general recommendations. If you’re transitioning plants from legacy lighting sources to LED, you probably want to start on the high end of the scale of mounting heights listed below and gradually lower the fixture to increase intensity as your plants adapt to their new lighting source.
NeoSol LS Coverage Area
Purchasing a single NeoSol LS? Expect your NeoSol LS to cover a 3' x 1.5' area, and plan to hang your light no closer than 12" from the canopy. This setup is best for seedling propagation.

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 light Illumitex LED grow lights deliver to the plant encourages increased leaf accumulation to intercept more light and increase production further.

LED lights are much more energy-efficient than most other forms of lighting, so growers’ energy bills are greatly reduced. LED grow lights don’t generate as much heat as legacy lighting types and so external cooling systems are unnecessary. LEDs offer scientifically tuned spectra for different plant growth and different stages of growth.
Photosynthetically Active Radiation (PAR) is reported as millimoles of light energy per square meter.
Photosynthetic Photon Flux Density (PPFD) is measured in micromoles per square meter per second. This metric represents the total number of photons in the photosynthetically active range of wavelengths falling on a square meter of a given surface (such as a plant canopy) every second. In horticultural lighting applications, it is used instead of illuminance (which is measured in lux or footcandles).

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 Illumitex's LEDs are rated to at least 50,000 hours at L70 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. So how long do LEDs last? Illumitex LEDs last a long time.
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.
When your order ships, we'll send you an email with a tracking number.
Illumitex LED Lighting products are designed to last for tens of thousands of hours — many times the life of a typical incandescent bulb and 5 times the lifetime of an average compact fluorescent lamp (CFL). Incredible longevity means that you might never change another light again, and at the very least, you'll have significantly lower maintenance and labor expenses. In addition, Illumitex offers simple retrofit solutions, so converting from old technology to LED is easy.
We're on it! All of our grow lights are shipped in discreet packaging.
The IP stands for Ingress (the act of entering) Protection. The first numerical digit describes the rating that is given for solid objects. The 6 here is the highest rating and means the LED is dust tight. The second numerical digit defines how well the LED can keep liquid out. On a scale of 1-8, 6 is pretty high, meaning Illumitex's IP66-rated LEDs are very water tight and suitable for installations where they're likely to be sprayed by water, such as horticultural and agricultural applications.
No. Research shows that plants primarily absorb light from much more narrow areas of the light spectrum — blue and red regions, specifically. Chlorophyll — the plant structure in which photosynthesis occurs — absorbs peak wavelengths around 450nm and 660nm (blue and red, respectively). Giving plants only the light they need — red and blue vs. “full spectrum” — is important when considering energy usage.
There is an optimal temperature for photosynthesis, and any temperature higher or lower than that will decrease the rate of photosynthesis. Photosynthesis temperatures too small or great can actually kill plant cells, as cells are made up of mostly water and water evaporates at high temperatures and freezes at low temperatures. By using and LED grow light, temperature management can be more efficiently controlled when compared to HID lighting like high pressure sodium or metal halide lamps. For example, the NeoSol NS puts out about 61% less BTUs than a 600W HPS bulb and ballast system, giving growers a more efficient growing environment to control.

Long day plant (LDP) is a plant that only flowers during long days (qualitative LDP) or whose flower is accelerated by long days (quantitative LDP).
Long-short-day plants are plants that flower only after a sequence of long days followed by short days.
Low-fluence responses are phytochrome responses that require the fluence to reach 1.0 µmol m-2, and are saturated at about 1000 µmol m-2. They include most of the red/far red photoreversible responses, such as the promotion of lettuce seed germination and the regulation of leaf movements.
Lumen (lm) is a measure of luminous flux or quantity of light emitted by a source.
A lux is one lumen per square meter; differs from foot-candle by about a factor of 10.
Microeinstein is the unit equal to one millionth of an einstein, which is one mole of photons, regardless of frequency, as used to measure irradiance. The einstein has been used to represent the quantity of radiant energy in Avogadro's number of photons and also Avogadro's number of photons. The second definition has the einstein equal a mole of photons. While commonly used as a unit for photosynthetically active radiation (PAR), the einstein is not an SI unit.
Mole is based on the number of photons in a certain waveband incident per unit time (s) on a unit area (m2) divided by the Avogadro constant (6.022 x 1023 mol-1). It is used commonly to describe PAR in the 400-700 nm waveband.
The chlorophyll of the photosystem II reaction center that absorbs maximally at 680 nm in its neutral state. The P stands for pigment.
The chlorophyll of the photosystem I reaction center that absorbs maximally at 700 nm in its neutral state. The P stands for pigment.
The far-red light-absorbing form of the phytochromes converted from Pr by the action of red light. The blue-green colored Pfr is converted back to Pr by far-red light. Pfr is the physiologically active form of phytochrome.
Photochemistry is very rapid chemical reactions in which light energy absorbed by a molecule causes a chemical reaction to occur.
Photoinhibition is the inhibition of photosynthesis by excess light.
Photomorphogenesis is the influence and specific roles of light on plant development. In the seedling, light-induced changes in gene expression to support above-ground growth in the light rather than below-ground growth in the dark.
A photon is a discrete physical unit of radiant energy.
A photoperiod the amount of time per day that a plant is exposed to light or darkness. May control various aspects of sexual or vegetative reproductive development, including flowering.
Photosynthate is the carbon-containing products of photosynthesis.
Photosynthesis is the conversion of light energy to chemical energy by photosynthetic pigments using H2O and CO2, and producing carbohydrates.

Phyotsynthetically active radiation is light wavelengths between 400 to 700 nm range that corresponds to the wave band absorbed by photosynthetic pigments.
Photosystem is a functional unit in the chloroplast that harvests light energy to power electron transfer and to generate a proton motive force used to synthesize ATP.
A system of photoreactions that absorbs maximally far-red light (700nm), oxidizes plastocyanin and reduces ferredoxin.
A system of photoreactions that absorbs maximally red light (680nm), oxidizes water and reduces plastoquinone. Operates very poorly under far-red light.
Phototropins 1 and 2 are two flavoproteins that are the photoreceptors for the blue-light signaling pathway that induces phototropic bending. They also mediate chloroplast movements and participate in stomatal opening in response to blue light. Phototropins are autophosphorylating protein kinases whose activity is stimulated by blue light.
Phototropism is the alteration of plant growth patterns in response to the direction of incident radiation (light).
Phytochrome is a plant growth-regulation photoreceptor protein that absorbs primarily red light and far-red light, but also absorbs blue light. The holoprotein that contains the chromophore phytochromobilin.
Red-light absorbing phytochromes form. This is the form in which phytochromes is assembled. The blue-colored Pr is converted by red light to the far-red light-absorbing form, Pfr.
A short day plant (SDP) is one that only flowers during short days (qualitative SDP) or whose flower is accelerated by short days (quantitative SDP).
LEDs offer many advantages over legacy light sources, including extreme durability and high efficacy. Their superior lifespan, when compared to other lighting types, means their required maintenance and need for replacement is great reduced. This means LED lights offer great maintenance savings, energy savings and environmental sustainability. LED lights can offer greater optical control, instant on/off, dimming, and reduced rate of lumen depreciation. LEDs also produce a significantly smaller amount of heat than traditional HID lights.

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.

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.
For horticultural grow lights, lux and lumens are meaningless measurements.
Lumens are a measurement of how much light energy a light source emits. The problem is that this measurement is based around the wavelengths of the human eye, and NOT the photosynthetically active radiation (what plants "see") wavelengths. It makes sense to use lumens when measuring lights used in flashlights or high bay applications, but means nothing when it comes to grow lights.
Lux is a measurement of how much light reaches a surface (Lumens/m^2), but this measurement is based upon lumens and is not an appropriate measurement for horticulture grow lights.
PAR is defined by the International Commission on Illumination as the total photon exposure in the 400nm to 700nm waveband range of radiation that is absorbed by photosynthetic pigments. PAR is not a quantitative measure; it’s merely a description of the light that plants need for photosynthesis. PPFD, on the other hand, is a quantifiable measure of the total number of photons in the photosynthetically active range of wavelengths that fall on a square meter of a given surface (say, a plant canopy) every second. In other words, PPFD is a measured metric whereas PAR is merely a descriptive term for a range of wavelengths.
Chlorophyll B has a peak absorption response at 450nm and 660nm.
Chlorophyll A has a peak absorption response at 430nm and 680nm.
