Re: [APD] New CFL screwin bulb - array

["S. Hieber" <shieber at yahoo_com>]

Just about any type of lighting if you have enough and you can fit it over your tank. There's no magic "correct" number of watts, lumens, photons, etc. Incandescents would work if you could fit enough of them and handle the heat.

Shop lights work., MHs work; plants are terribly forgiving in these regards.

I've been using them for three months while waiting for my gear to get out of storage. I used reflector domes, screwed in a Y adapter and screwed two bulbs in each dome (4). I forget the watts (23?) but it's the 100W output claim. I come home and the tank is boiling (pearling) the plants grow along the bottom. many green plants have reddish color to leaves. Riccia looks like a mound of diamonds (o2 bubbles just grow all day) My tank is deep, 24". I used the daylghts from Walmart, cheap but I've had a few duds. I had a lot of glosso floating and it turned red around the edges. I have a layer of duckweed to soften the light now. I didn't bother with timers because it's only temporary. 
If you build an array, polished reflectors, dome or regular,  help greatly and working out a timer sequence will get all the light you need. I don't know what the electric costs work out to but my guess is less. 8x23=184 vs ??
