Ouch. Sounds like having two timers is going to be the hot setup. Have one
pair on for the whole photo period, the second pair on a few hours around
high noon.

The kits for 36, 40 and 55 have the same hardware and don't include the
bulbs. We could buy 2 55w and 2 40w bulbs. Or buy all 55w then replace one
pair with 40w if it's "too bright" and save the replaced 55w as a spare.

I wonder how long a "5' bulb" plus encaps would be? 5'1"? The hood already
exists. Might this be a half inch too long? We have no problem with 4' bulbs
in a 5' tank (plenty of room for endcaps!) and the CF kits can be nicely
centered. Nah, "never buy weird size bulbs". Hard to find and cost more than
