Mark,
As I understand it, these are the ones that fit into a socket such as you
would have on a desk lamp. What sort of fixture do you use then that would
put the light immediately above the plants in a long bank of flats? I am
thinking about something that would replace my four chain-hung shop lights
in a double row 8' long.
