Lamp Type Watts Lumens per bulb Total efficiency
Fluorescent Bulb 40 3 000 400 watts = 30k lumens
Mercury Vapour 175 8 000 400 watts = 20k lumens
Metal Halide 400 36 000 400 watts = 36k lumens
High P. Sodium 400 45 000 400 watts = 45k lumens
Notice the Mercury Vapour lamps are less efficient than the fluorescent (FL), and can
not be positioned as close to the plants, so the plants will not be able to use as much of the MV
light. The light distribution is not as good either.
