Is CMH cooler than HPS?
Due to the lower heat output of LED’s, heat may need to be added to the grow room in colder months which will increase costs. CMH fixtures put off more heat than LED’s, but less heat than their HPS counterparts.

What’s the difference between HPS and CMH?
CMHs Run Cooler than HPS Lights — Another benefit of CMH lights over HPS bulbs is that they produce less heat. Even a 630w CMH light will run cooler than a 600w HPS bulb. So while HPS lights are cheaper overall, CMH lights will definitely save you some cooling costs during those hot summer months.
Are CMH lights good for growing?

How long do high pressure sodium bulbs last?
High Pressure Sodium lights maintain their luminescence fairly well with 90% still available halfway through their lifespan (around 12,000 hours). HPS bulbs typically emit 80% of their original rated output at the end of life (around 24,000 hours).
Can you touch a CMH bulb?

Is CDM better than HPS?
The enhanced spectrum of light emitted from a CDM grow light will increase complex sugar production and essential oils within a plant in comparison to a standard HPS grow light, and in doing so will enhance the flavour of produce and increase the overall quality of yield.
