I'm resurrecting an old 120g and I'll probably build a new canopy for it. I can have something made out of stainless steel, so shape is not an issue. The tank top is 60" x 18".

With your experience with these screw-in fluorescents, do you think it is worthwhile investigating their use, or do you think I should stick with my garden-variety and inexpensive approach using multiple inexpensive lamps? I looked into halogen spot lighting, but their efficiency is not much better than incandescent, though I may still use it for accents (I want that shadow ripple across the bottom of the tank for the evening transition), and for helping certain plants. I have the feeling that if I can wait long enough, there will be a solution available using LEDs. Now that would be interesting, especially is I could dim them, and turn on different banks for changes in hue (a slight blue tinge in an open area, red-brown hue over the plants).

Thanks for any feedback. They already are available if you homebrew it. Look for Luxeons not LED's. I currenlty have an array of 24, 3 watters that are doing a great job on a reef tank.

I have a mix of 460-470 nm luxeons mixed in o9n a separate circuit that also doubles as my moon lights at night......next project is a mix of reds and oranges trying to duplicate sunrise/sunset . Even the SPS and clams I have in this tank are doing fine, all illuminated with Luxeons, no PC or MH of any type. -- \\\|/// ( @ @ ) -----------oOOo(_)oOOo--------------- oooO ---------( )----Oooo---------------- \ ( ( ) \_) ) / (_/ The original frugal ponder !

The Luxeon LEDs are awesome. They are VERY expensive though.

yep, thats for sure, but they can be had fairly cheap if yu look. I
give less than $4 each for the ones I have, but have seen em online at so called bargain basement prices of $11 each... Best route to buy luxeons is get a few folks together that have an interest in them and make a larger order, or find someone that orders lots of stuff from that supplier and add your order to it....

They suck because they emit lihgt in a radial pattern. Like a ilght buld which ic of course why they're made that way. Now, compare them to a fluorescent tube, and think where that puts the light compared to a screw in. I think you're a little out of date. Sure, there are lots of twisted screw-in fluorescents out there. They weren't what I was talking about, but yes I've used screw-ins as well. But I used screw-in fluorescents with U-tubes, just like the regular CFs. AllGlass even makes one (10W) and I've seen its duplicate at Walmart. Walmart also has some 15W,6500K ones with 4 U-tubes and I've seen some at Home Depot that are up in the 50-100 watt range, but I don't know about the color temperature. OK, the ones with multiple U-tubes may not be quite as efficient as the long single U-tubes, but I can easily fit 4 15 watt ones into a 30" hood that held a single 18 (or is it 20?) watt tube. That's a big improvement. -- It's turtles, all the way down |

I'm sure Richard will have an opinion, but I can only say I've got 2 of the AllGlass/Walmart 10W, 6500K lamps in a 10 gallon hood and one in a 5.5gallon hood. The light looks good and the plants grow like crazy. I've got 4 15W,6500K that I'm putting into a 29 gallon hood, but it isn't operational yet. And if I can afford that 40 breeder I'm looking at I'll use 5 or 6 of the 15W ones mounted crossways. And maybe a blue Xmas tree bulb or two for night lighting - or maybe LEDs. -- It's turtles, all the way down |

Thanks for any feedback. Spiral compact screw-in bulbs get shot down on the AGA mailing list every time they're mentioned. Folks have measured lumens from them and they put out far less light than the same wattage T5. Somehow a lot of light is wasted by the spiral shape. I don't know how they compare to hardware store T12s, but you'll certainly get more even lighting from long tubes. -- Elaine T __ http://eethomp.com/fish.html '__ rec.aquaria.* FAQ http://faq.thekrib.com |

I don't know how they compare to hardware store T12s, but you'll certainly get more even lighting from long tubes. That doesn't surprise me. I use long tubes and 65W PCs on my display tanks. But cost is a factor, and if I'm not doing anything special with a tank, I'll take the cheap way out. I see these as a step up from incadescents. And everyday run of the mill plants do just fine in them. And I must continue to stress that one must take the time to ensure their spiral screw-ins are not the general use bulbs found in hardware stores, but 6500 or full spectrum found in gardening and fish catalogs. Come to think of it, they're not all spirals - I've got a couple that measure about 6 inches long, mounted to their screw-in balast with a 2 pin connection. Westinghouse. Since they are u shaped bulbs, like bigger PCs, that's 12 inches of tube per bulb. Lot of light. 2 13 watters equivalent to around 100 watts. And they've got to be better than the 15 and 20 watt straight flourescents supplied with commercial hoods and strip lights for 15 or 20 gallon tanks.. Mr Gardener |
