What Should You Consider When Choosing CDM Lighting for Indoor Growing?

I’ve been looking into different lighting options for indoor growing and wanted to compare CDM systems with other types of grow lighting. Things like light coverage, wattage, heat output, reflector compatibility, and the size of the growing area seem important when choosing the right setup.

I found this collection while researching CDM lighting options: https://hydro-land.co.uk/collection/lighting/cdm-grow-lights/

For growers who have used CDM lights before, what do you normally consider when choosing a setup? I’d especially like to hear how you manage heat and decide what wattage is suitable for your growing spa
