Re: [APD] New CFL screwin bulb - array
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 ??
