Frequently Asked Questions

We have included several definitions below of terms that we most often get asked about!

Discrete bundle (quantum) of electromagnetic radiation (light). Can be considered to be a particle (although it displays properties of waves as well). The energy of a photon depends upon its wavelength. Conversely, if the energy & wavelength are known, the number of photons can be calculated.

The measurement of radiation between 400 nm and 700 nm. Spectral region most useful to plants for photosynthesis.

The amount of radiation between 400nm and 700nm. Radiation hitting a surface photosynthesis: A process used by plants and other organisms to convert light energy into chemical energy that can be later released to fuel the organisms’ activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water.

Daily Light Integral (DLI) is the number of light particles, also called photons, that are received during a 24-hour time span in one location.

Plants require photons for photosynthesis, which is the process of converting light and carbon dioxide into sugar and oxygen so that the plant can survive and grow.

650 Watt LED vs 1150 Watt HPS Cost Comparison

Running our 650 watt LED over 1150w HPS will give you power savings of approximately 46% with nearly the same light output.
Moving up to our 1100 watt light will give you far more Photon energy over HPS with still saving approximately 18% with a 39% increase in light output.

Here is a example:

A 10 light room (650watt lights) with a upfront cost of approximately $20,000.
The power savings at the wall and cooling cost of our LED vs HPS would be $410.05 per year, per light.
$410.05 x 10 lights = $4,100.50
$4,100.50 in savings per year × 50,000 hours on a 12/12 cycle = $47,155.75 in power savings over 50,000 hours!
Approximate cost of maintenance of HPS over the 50,000 hours in $2300.
Approximate cost of maintenance of LED over the 50,000 hours in $0.
In conclusion over the 50,000 hours our lights will pay for themselves and give you a approximate total savings of $27,155

LED vs HPS Greenhouse Light Operating Cost Comparison

100 Light Example

Return on Investment

An 100 light greenhouse comes with an upfront cost of approximately $139,000.
The power drawn at the wall and cooling cost savings of our 530w LED vs 1000 watt HPS would be $395 per light per year.
$395+$100 maintenance times 100 lights equals an annual savings of $49,537.
$49,537 in savings per year divided by the $139,000 upfront cost means the lights will be fully paid off in 2.8 years. In conclusion over the 10 years the 100 lights will pay for themselves and give you an approximate total savings of $361,865.
