Those latest pictures are kind of misleading. The height is about 3-4" right now. I'd like to lower them more, but the poor ventilation seems to cause the leaves to contract. I believe this is due to heat. The cones above each seem to work pretty well though. I would like to lower the lights, but I seriously need better ventilation. I just don't know how to do it without drilling holes in the board that holds the light fixtures.
