HPS VS SUN VS LED VS CMH

I created this for informational purposes, images used in this article have been sourced via google. In this article we will cover spectrum analysis. We will start by showing the difference between the various types of horticultural lighting in today’s market.
Overall the most commonly used form of light used
in the horticultural industry. Growers that use HPS
lights achieve an average of ½ a gram per watt yield.
This is due to the lack of spectrum your plant truly
Needs to thrive. No harmful UV or radiation though
10,000 - 24,000 hour bulb replacement intervals.
Omnidirectional (360o) which wastes light making them
Less Efficient. Bulbs are explosive and contain mercury.
High temperature output leading to more waste in the
Form of AC supplementation.
Where do I start haha. This is obviously the best
Choice for any grower for only the most obvious
reasons. The sun is natural and free. The sun offers
the fullest and largest spectrum. However, plants do
not love all the spectrums the sun provides. IR and
certain forms of UV can be harmful to your plant.
Not saying the sun is bad for your plants by any
means. The sun will always reign supreme.
Truly the future in the horticulture industry.
Growers that use this style of lighting can achieve
A whopping 1-1.75 gram per watt yield. This is due to
the full spectrum of light high-power LEDs emit.
50,000 hour replacement intervals. Directional lighting (180o) wastes less energy. Runs at a significantly lower temperature than Traditional lighting. Decreased risk of fire. No cooling necessary and water resistant
This form of light runs the same way as
traditional metal halide lights, only they
have ceramic bases. Run cooler than MH
and HPS. Omnidirectional (360o) which wastes
light making them Less Efficient. Bulbs
are explosive and Contain uranium hexafluoride
which can cause mutations, cancer, birth defects.
Highly corrosive. It is radioactive!!!
Why do they explode?
Ceramic Metal halide lamps contain high-pressure gases in the arc tube. In the case of non-passive failure, the pressurized arc tube within the lamp causes the explosion. When the arc tube explodes, molten glass can fall from the fixture, which presents an obvious issue if a fixture is installed above flammable materials.
