While shopping at Wally World yesterday, I found a 24" fluorescent tube/fixture combo for $10 so I thought I'd add it to my setup which already had 2 CF's and one incandescent. The results were very pleasing. :-) Bigger numbers all around and I got to see my first ever Io Moth. Ken Childs Henderson, TN Chester County http://www.finishflagfarms.com
