Sun System Grow Lights – Introduction & Comprehensive Review

We are living at a time when urban life is the trend. People are moving from the less populated rural areas to the densely populated towns and cities. To plant-loving individuals, living in an urban setting does not help.

Despite all these challenges, many people have discovered new methods to grow their favorite plants. Even if it means turning the interior of the houses into a garden.

From the basic biology we learned in childhood, we know that a plant requires three components to grow. These components are oxygen, nutrients, and light.

Plants use light to synthesize their food in a process referred to as photosynthesis. In the open, the sun provides this light. Grow lights are used as an alternative to the sun.

They are also used to supplement natural light. Before getting into the different kinds of grow lights, there is a need to grasp the basic principles of lighting.

Light Spectrum

The visible white light is composed of different wavelengths which can be measured. Not every wavelength is suitable for plants. Plants capture and utilize light bands with a spectrum ranging between 400 and 700 nanometers.

This band is known as photosynthetically active radiation (PAR). Even within the photosynthetically active radiation spectrum, different wavelengths are needed at various stages of plant growth.

The blue light spectrum (440-490 nm) supports vegetative growth, while light in the red/orange range (580-700 nm) is ideal for flowering and fruit development.

Light Intensity

The various kinds of grow lights generate light of different strengths. However, the intensity must be sufficient enough to support plant growth.

The grow lights should be positioned well. Positioning the lights further away from the plants will result in less light energy reaching the plants.


Photoperiod refers to the amount of light in 24 hours. It determines when the plants will flower or fruit. Grow lights used for indoor gardening ought to be synchronized with the natural seasons. To achieve such a photoperiod, the grow lights are connected and controlled by timers and alarms.

Sun System Grow Lights: Overview

The Sun System Company produces an array of the latest state-of-the-art grow light technologies. The company is considered one of the best and a powerhouse for the production of grow lights. 

Sun System grow lights are manufactured using top quality components. The grow lights are designed in such a way that ensure maximum efficiency and high yields.

Most importantly, Sun System provides grow lights to growers of all scales. Whether one owns a miniature indoor garden or a huge grow room, there is always a grow light designed for them. As already mentioned, Sun System manufactures different kinds of grow lights. These lights include:

  • LEC grow lights
  • Fluorescent grow lights
  • Metal halide and high-pressure sodium lamps

LEC Grow Lights

Sun Systems has developed light-emitting ceramics (LEC) or ceramic metal halides to replace the traditional metal halides and high-pressure sodium lamps. The LEC grow light is next-generation technology. These lights not only have a wide spectral range but also emits very little heat.

As a result, unlike the traditional high-intensity discharge lighting systems, LEC grow lights can be used safely in the smallest spaces. There is no need to install ventilation systems in such confined spaces. The lights can be placed near the plant’s canopy without subjecting the plant to desiccation.

The extremely low heat energy generation by LEC grow lights guarantee less power consumption and increased longevity. Their full spectral range ensures optimal plant growth.

Only one lamp is required to achieve full-cycle growth. The LEC grow lights can also be used to supplement traditional high-intensity lights. They broaden the spectral range, ensuring that the light requirements for the later stages of plant growth and flowering are met.

Fluorescent Grow Lights

Like all other Sun System grow lights, Sun System fluorescent grow lights are of exceptionally high and impressive quality. These lights are suitable for those growers with tight spaces. Fluorescent lights are the best for seed propagation. The fluorescent light emits light of lower intensity.

Germinating seeds or rooting clones require light of slightly lesser intensity compared to plants at the vegetative or flowering stages.

For this reason, fluorescent grow lights are routinely used as supplemental side lighting. This does not imply that they cannot be used as stand-alone lighting.

Like their LEC counterparts, fluorescent grow lights emits minimal amounts of heat energy. As a result, they can be placed close to the plant without any harmful effects on the plants’ foliage. Less heat generation guarantees longevity, power saving, and cost-effectiveness in the long run.

Metal Halide and High-Pressure Sodium Lamps

The Sun System metal halide and high-pressure sodium lamps represent a category of tried and tested grow lights. These high-intensity discharge grow lights are a darling to many growers.

Their immense power and low-cost guarantee optimum yields. As a result, metal halide and high-pressure sodium lamps are the recommended choices for large-scale grow rooms. They are the best option for those growers with lots of plants and seeking maximum yields.

Sun System’s high-intensity discharge grow lights have a unique feature that sets it apart from the rest. They have an integrated Galaxy electronic ballast. This amazing feature enables the synchronous operation of both the metal halide and high-pressure sodium lamps.

The two lights are suited for different stages of plant growth. The metal halide lights emit light within the blue spectral range. Such light is suitable for the vegetative stage. The high-pressure sodium light emits red/orange light which supports flowering.
