This is a reddish light and is the more efficient of the two lights, emitting more lumens of light per watt of electricity used.
It is commonly used to supplement daylight in a greenhouse, solarium or south facing window. It is switched on during cloudy days or when the sun sets to extend the daylight hours.
It is also useful indoors if growing plants that are all in a bloom state such as chilies, strawberries or beans. Halide conversion bulbs are available that deliver halide light from a High Pressure Sodium system.

Shake off all the fears of servile prejudices, under which weak minds are servilely crouched. Fix reason firmly in her seat, and call on her tribunal for every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason than that of blindfolded fear.
