In a typical greenhouse environment, certain parts of the electromagnetic radiation emitted by the sun encourage plant characteristics that are undesirable, such as plant stretch induced by 730nm far red radiation. We counter these effects with an increase in 400-450nm composition in LX-GML Greenhouse.

All Luxint systems are passively cooled using natural convection without the need for a fan. We do not believe in installing cooling fans inside LED fixtures. On average, LEDs should yield approximately 50,000 hours of useful life. However, no fan is going to last this long in wet/damp/harsh/dirty environments typical in horticulture environments. If the fan fails after 10,000 hours, the LEDs would fail shortly after. In addition, fans require energy to operate, and fans don’t grow plants. We prefer every joule of energy go toward photon emission. Hence, we do not believe this is an acceptable engineering design for LED fixtures.

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. Fluence 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.

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. 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.

μmol/J stands for micromole per Joule. It is a measurement to determine how efficient a light is at converting electrons into photons. Luxint 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.
