What our products do and how they do it.


  • What product do you recommend?

    ▪ The determining factor for which product model is best for your operation is dependent upon your goals and environment. There are numerous variables that will determine which product is best for your growing environment.
    ▪ Basic recommendation as below, For Indoor vertical farm: Model HYGL8 For Tissue cultural: Model TSGL8 or TSGL8R For Speed breeding: Model GHGL For vertical wall: Model GWGL.
    ▪ For more details send us inquiry on

  • Are Nexsel grow lights are actively cooled or passively?

    Its depends on model Following models are passively cooled

    ▪ HYGL8
    ▪ TSGL8
    ▪ TSGL8R
    ▪ GHGL 180
    Following model are actively cooled
    ▪ GHGL 3-S
    ▪ MSTL

  • Do your fixtures produce heat?

    Yes, all lighting systems produce heat, but our systems dissipate the heat differently than other LED systems, fluorescent or HID (i.e. metal halide) lighting systems. Fluorescent and HID lighting systems largely rely on radiative heat transfer from the front side of the fixture. This is why you can feel the heat if you place your hand in front of these lighting systems. This is compounded by the aluminum reflectors that are commonly used in these systems, and this can have a substantial impact on the temperature at canopy level. Nexsel systems rely on conduction and convection as the main heat transfer methods. This is why the heat sink on back of our fixtures will feel warm/hot. Since convection is carrying the heat away from the fixture from the top of the fixture, your canopy temperature will be minimally impacted compared to using a fluorescent and/or HID lighting system.

  • Do Nexsel lights get hot?

    This depends on the air temperature and air velocity around the fixture. If you have air flowing around the lights, they will barely feel warm.( 32 to 40 Degree C) However, if the air surrounding the fixture is hot or there is very little air movement, the fixture will feel very hot. This is normal because the fixture housing draws heat away from the LEDs by design. However, these are high-power lighting systems, so we do not recommend touching them.

  • What is umol/J and why does it matter?

    umol/J stands for micromole per Joule. It is a measurement to determine how efficient a light is at converting electrons into photons. Nexsel lighting systems are some of the most efficient on Earth. They are also some of the most powerful. It’s the balance between the two that we strive for real-world application. More on this later.

  • What is CRI and is it important to the development of my plants?

    A light’s color rendering index (CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal light source (i.e. the sun). This value is not important to how a plant responds or photosynthesizes. Where CRI is important is how well you can tell the true color of something, for example a leaf that might be chlorotic (lacking green). When you have an ideal CRI it is easier to detect color variations that might be indicating poor plant health. HYGL8 has a CRI of 85. For comparison, HPS has a CRI of 25.

  • What is PAR?

    Plants are photoautotroph's – using a narrow band of light between 400nm -700nm as a source of energy to make food molecules from carbon dioxide and water. This process is photosynthesis (the most important chemical process on Earth). The only type of light which enables photosynthesis is defined as Photosynthetically Active Radiation (PAR): the narrow band of light between 400nm – 700nm. Light outside of this range is not photosynthetically active and will not generate greater biomass for those seeking improved yield.

  • What is PPF?

    An electronic light source converts electrons into photons. Lights for human vision measure output with lumens (measured in lux or footcandles). Lights for photobiological reactions measure output with photosynthetic photon flux (PPF). PPF tells us how much PAR a light source emits. Where PPF measures total PAR output of a lighting system, PPFD measures how much of that light is delivered to a canopy.
