I've seen no data one way or another, but based upon the way they work, I
doubt that HI fluorescents have as much output as the HID's. Might be time
to invest in a higher wattage version of the latter.

I'm bringing in the Catts that have summered outdoors. They grew. Not
all of them will fit under the HID lights/south-facing window anymore.
I've heard there's a new high-intensity flourescent light that is
suitable for Catts and Dendrobiums. Does anyone have any experience
with them? Know a good place to buy them?
