Are CMH Grow Lights Cooler than HPS Grow Lights? 420 Guide for Beginners 2020
Best HID grow lights work because of gasses, not wires or chips. The type of gas and chemicals used in HID grow bulbs- like mercury and metal halides- react with each other to give you light. As the bulb gets brighter and brighter, it gives off heat. That heat is pretty intense and will radiate from the bulb. The higher the temperature and the longer you run it, the hotter the bulb and your grow room will become. Now, it should be noted that CMH’s run in the same way standard MH’s run, only they have ceramic bases. However, ceramic metal halide bulbs run a lot cooler than MH and HPS bulbs by about 8°F. An LED ran cooler than CMH’s by at least 2°F, and overall 10°F lower temperature from a higher-powered LED. What is a Ceramic Metal Halide Grow Light? First of all, what are these lights actually called? Ceramic Metal Halide (CMH)? Light Emitting Ceramic (LEC)? Or are they Ceramic Discharge Metal Halide (CDM)? The truth is that all those different names are talking about the sa...
