Choosing lighting for an indoor growing setup can take some research because different fixtures are designed for different spaces and growing requirements. Coverage, power consumption, heat output, mounting height, and light intensity are some of the factors I would check before making a decision.

I also think it helps to consider the plants and growth stage before choosing a particular lighting technology. A setup for seedlings or propagation may have different requirements from one designed for mature plants.

For anyone comparing CDM lighting options, you can view range to see the available choices and compare them according to your growing space.

What specifications do you normally check first when choosing a grow light?
