We should be able to see at least 2000 stars on a clear night. For over 265 million people living in the 21 mega cities of the world, the night sky is maybe two dozen stars. The culprit is light pollution. The broadest definition of light pollution includes any artificial light source. More specifically, light pollution is unused or misdirected light that disrupts entire ecosystems. If you consider the amount of energy required to light the sky at night, you will understand the incredible waste involved in doing so. It should be noted that LEDs are not currently the solution to light pollution in most lighting applications. "White Light" LEDs have the same drawbacks (some say more) as traditional lighting. Where LEDs can make a difference is in horticultural lighting.

As more growers look to year round production in the greenhouse, we begin to see a corresponding increase in lawsuits filed by Municipalities and neighbors upset by the effect of supplemental lighting on the night sky. The most common form of supplemental lighting used in greenhouses is the High Intensity Discharge lamp (HID). Despite reflectors by design HID bulbs emit light in all directions. This problem is amplified by the fact that very little of the light emitted from an HID bulb falls within the wavelengths that plants readily absorb. Light that is not absorbed is reflected.

LED Grow Master Global, LLC provides a solution. LGM LEDs are designed to minimize wasted light on several fronts. First, LED Grow Master lighting is a directional light source. Instead of spreading light 365 degrees like traditional lighting, LEDs enable us to utilize two relatively narrow beam spreads of 33 degrees and 45 degrees. A grower is literally able to direct light only where it is needed.

The second part of this control lies in the modular design. Each LGM LED plant light can be used alone or attached to multiple units with a simple connect cable. To understand the benefit of a scalable light source in regards to light pollution, one must simply understand that it is wasted light causing a problem. This wasted light is often in the form of using more light tan you need. Light output isn't measured in watts but the following example should give you the basic idea. A general rule of thumb for HID lighting in a greenhouse is that a 1,000 watt bulb will cover a 10' x 10' area. Maybe the plot is a 9' x 9' area. Does that mean the grower uses a 900 watt bulb? No, the grower still uses a 1,000 watt because its what's available. Multiply this waste by 1,000s of bulbs utilized in large greenhouse operations. LGM LEDs are scalable in 9 watt increments. Growers can use only what they need.

The last and most important aspect of LED Grow Master lighting in the fight against light pollution lies in the wavelengths of light that make up each cluster of LEDs. Over 60% of the light emitted is barely perceptible to the human eye and over 90% falls within the absorption peaks for photosynthesis. Light that is absorbed is not reflected. Here is to neighbor relations.
