No, but I do tend to place them all in the same general category. In
this case I would tend to leave the sodium out of the running, but I have
also seen them used commercially.

the cost of lamps, fixtures and power strongly favors the mercury vapor.
Just ask any pot grower.


I think you are confusing mercury vapor lamps with high pressure sodium
(HPS) or metal halide (MH).
