You can use a couple of clamp-on work lights. and clamp them to a freestanding coat rack. Use CFL's. They come in all sizes up to 4000 lumens. Being in zone 8A, it is probably safe to take the trees out side for real light. If you do: take time to acclimate them to the sun light I start on overcast days. Citrus trees are so specialized that the citrus forum is the correct place for this. Its not the lights that are the problem. Its how to install them. That is what makes citrus hard to grow. Your currant set up looks fine. Window choise is also important At winter solstice the sun come up and set south of due east or west that east and west windows are almost useless. You live far enough south that there is no need to worry about changing windows as I do in zone 6A. Just put your trees outside. If you use 48 " tube fluorescents Buy either T-5 or T-8 T-5 are a little better but more expensive T-8 are more common and are often sold very cheap as a loss leader to get you into their store. I saw your thread on LED light in the citrus forum. You got very accurate advice. I believe the two BOZO'S in the T-5 vs T-8 were having fun with each other. I know poncirusguy was because thats me. Another choice would be a floor lamp with 4 or 5 aimable lights.

I agree that this particular lamp looks somewhat different from Rohde's more familiar deco styled designs, but I can also see some striking similarities. When I first saw this particular lamp, its (for lack of a better term) "stacked finials" at the base of the lamp, rise over 21" off the ground. I've never seen anything quite like it before. It's very unusual! I also think the saturn like design element near the top of the lamp is very deco/industrial age looking. The only other similarly designed lamp that I've ever seen like this one, is the one that I posted at the bottom. It's a M.S.L.C. lamp designed by Gilbert Rohde. I have also learned from a source that in the 30's, Gilbert Rohde designed over 35 different lamps for Mutual Sunset Lamp Co., but many were undocumented. I have a sneaking suspicion that this is one of them. I have seen other M.S.L.C. lamps but they are very "traditional" looking. Unlike this one. Maybe this is going to be one for the history detectives! ;)

kathy....there was already a hole in it...the base screwed onto the glass bowl. I'm sure you could drill a hole in a bowl and achieve the same effect....just keep it cool while drilling with water, use a diamond drill bit....wear protective eyewear. OR.....last March I went to Hobby Lobby and found the exact same bowl on a 90% off rack. :0)

I've done the same when traveling Europe, Uk and Ireland. It's really nice. The cons to using one at home are are it uses electricity and will make your laundry room a little bit warmer. And they don't come cheap. YMMV In my laundry room (faces west and is very warm in summer anyway) I use the mainstream collapsible folding drying racks and a small table fan set on the floor to circulate air.
