Lighting Approach

HPS, LED, CMH and Hybrid Lighting Solutions

urban-gro’s suite of HPS, CMH and LED lighting solutions is designed with large-scale cannabis cultivation in mind to maximize yields and profitability of new and existing cultivation facilities. Our light options for grow environments and plant stages, include:

  • Indoor warehouse facilities where the lighting system provides 100% of the available light for Cannabis growth.
  • Greenhouses where the system provides supplemental lighting based on the Daily Light Integral. Our team of experts will guide the process to ensure optimal light is achieved.
  • Specific lighting to taylor the growth stages of clone, veg, mother, and bloom.

At urban-gro, we are committed to providing the most cost effective, efficient light source to the plant canopy by focusing on the cost of μmoles per photon delivered to the crop.

urban-gro supplies a wide variety of fixtures to ensure optimum plant growth and our detailed light plans prove it. urban-gro prepares a complimentary light plan to ensure that light uniformity and light levels are adequate for your crop. As technologies change, proper planning is essential to ensure light levels are not compromised in such a way that may negatively affect plant yield.

We invite you to embrace a better way to grow— your cannabis, your business, and your bottom line.

Assessing Needs & Maximizing Efficiency

urban-gro lighting design and products help maximize the yields and profitability of new and existing cultivation facilities.

By answering these four essential questions we are able to provide you with a customized complimentary lighting design plan to help improve your cultivation, maximize your yield, and get the best value—both in terms of the lighting system as well as the associated impact on the power grid.

The ultimate goal is to evaluate the initial capital cost of fixtures per photon delivered. The lowest lighting system costs are realized when an efficient fixture is paired with canopy photon capture.


What is the efficiency of the fixture? (Measured in μmoles/watt)


Is the spectrum correct for the stage of growth?


What is the target intensity for each stage of growth?


What is the capital cost per photon delivered to the plant canopy?

Science Meets Finance

Cannabis is a crop like any other, but it has unique technical, financial and legal considerations.

Learning Best Practices
Whereas all other crops have extensive research and study into best practices, legal Cannabis is a brand-new game, and thus, lacks the multitude on studies on best practices given to other horticultural commodities.

Those who will be the most successful cannabis growers need to find and align themselves with experienced professionals who can help them make decisions that take into consideration their particular set of challenges.

Protect Your Investment
As a crop, cannabis has the highest cost per pound market value compared to tomatoes, corn, or any other crop. This makes the investments to grow and protect a healthy crop and find ways to increase yield very important. However, as the prices for Cannabis decreases with more supply continuing to come online, growers need to find greater efficiencies.
High Cost of Energy
Energy is one of the greatest ongoing costs for growers, making up well over 50% of overhead costs. Finding ways to get maximum production per square foot and reducing the final cost of goods sold (COGS) is essential to yield a sustainable return on investment (ROI). Commercial grow facilities also require a significant capital invest both in terms of initial set up and ongoing upgrades and retrofitting. The choice of lighting is a key component.
Planning for Efficiency
At urban-gro, our Cannabis lighting division not only manufactures and sells the most respected lighting products in horticulture, we provide a comprehensive lighting system solutions for our clients. This includes working closely with clients to assess their situation and understand light level needs, power voltage, and cost considerations to deliver the best Cannabis lighting design plans and corresponding product solutions. These light plans map the number of fixtures and their location to ensure the necessary light intensity and uniformity.
Capital Improvement
Our professionally designed lighting plans and financial forecasting are useful in managing investor relationships and pursuing capital planning strategies. urban-gro prepares a complimentary light plan to ensure that light uniformity and light levels are adequate for your crop. Our professionally engineered plans guarantee light levels measured in μmol.
Rebate Programs
We are able to advise our clients on specific energy rebate programs for cultivation sites offered by various utility providers, helping them to prepare and present the application required to qualify for incentives.

Science Meets Finance

It starts by understanding DLI (daily light integral) which is the amount of PAR received each day as a function of light intensity (instantaneous light: μmol·m-2·s-1) and duration (day). It is expressed as moles of light (mol) per square meter (m-2) per day (d-1), or: mol·m-2·d-1 (moles per day).

Greenhouse growers can use light meters to measure the number of light photons that accumulate in a square meter over a 24-hour period. In a greenhouse, values seldom exceed 25 mol∙m-2∙d-1 due to glazing, structure, shadowing. In a warehouse environment 100% of the light comes from lighting fixtures and can also be measured with a professional light meter.

The DLI concept is like a rain gauge. Just as a rain gauge collects the total rain in a particular location over a period of time, DLI MEASURES THE TOTAL AMOUNT OF PAR RECEIVED IN A DAY.

As the Cannabis crop price decreases, it’s the efficient growers that will be successful. This starts with ensuring your lighting system is optimized for maximum plant growth.



As the market expands and production facilities scale to match commercial production in line with other agricultural products, professional designed and proven lighting system are advantageous for higher efficiencies and maximum yields. 

Reliable Products to Meet Your Needs

urban-gro offers a complete range of innovative fixtures, lamps, and reflectors for optimized light distribution in a variety of technologies including LED, High Pressure Sodium (HPS), Metal Halide (MH), Ceramic Metal Halide (CMH), and Hybrid systems. For each lighting solution, we provide a comprehensive light plan to ensure optimized crop growth through adequate light penetration and uniformity into the crop. 

As technologies evolve, proper planning is essential to ensure light levels maximize plant yield. urban-gro’s customized lighting plans allow for the proper micromole output with the fewest fixtures possible, saving substantial energy and cost. Additionally, many of our fixtures do not require reflector replacement annually. Instead, the design of the fixture allows for easy cleaning and maintenance, returning the reflectivity to near-new year after year.

Installation and Inspection

All products we offer are UL, ETL or CSA listed to ensure our clients don’t have issues during the inspection process. Our installations are backed by a warranty supported by a Colorado-based service center. UL Listed and available in 240V, 277V, 347V and 400V.
