lighting idea?
Perusing the web the other day, I came across compact fluorescent
sockets that could be screwed into an incandescent socket. Both inline and square pin versions. Seems like this would be another path to some cheap lighting. Has anyone else seen or used these? -- It's turtles, all the way down |

Coral life makes them, and thewre is some brand sold in wal mart whose
name I do not recall. The coral life is a 50/50 bulb which is fine for sal****er but not needed for fw or fw plants but it does add a nice blue hue to some fw things, and makes any florescent stuff on decorations stand out.... They do tend to run somewhat hotter than the typical incandescant lights do, and a bit hotter than equal true pin type PCs do....so just beaware heat may be an issue in some tanks / hoods On Thu, 26 Jan 2006 09:39:17 -0800, Larry Blanchard wrote: Perusing the web the other day, I came across compact fluorescent sockets that could be screwed into an incandescent socket.

I use them in my sump ... got nice ones with reflectors ...
output 10w ech equal to 100 w poped in 3 of these :) plants love it ... not nice for display tanks cause of the light http://www.smarthome.com/903240.html the suspended setup makes for very attractive lighting .... so probably depends on the type of fish you have ,,, "Roy" wrote in message ...

The ones that come with threads that fit an incandescent socket. That's not what I'm talking about, although I've used those. A regular compact fluorescent has either 4 pins in a straight line, or 4 pins in a rectangular arrangement. It won't screw in to anything. What I saw was an adaptor that did screw into a regular socket and then you could plug in the 4 pin compact bulb. Did that clarify what I'm talking about? -- It's turtles, all the way down |

Got you now........why not just buy a new ballast and wiring / socket
assembly...thats made for square pin or straight pin PC's. Hellolights.com has some on special. Ballast will power up a pin type PC and handle PC bulbs of 24 thru 65 watts in power for $24.00 That assembly comes with standard square pin configuration but a straight pin configuratin plug is only about $3.00 more for replacememnt socket. They also have 7/9 watt and 13 watt retro asemblies compelete with your choice of bulbs, and reflector included for about $15.

Well, you're talking $24 "on special" as opposed to $6.23 for the adaptor. The adaptor is only good for 23 watts, so your route is the way to go if you need more than that. -- It's turtles, all the way down |

The screw-in compact flourescent light bulbs are also available in
full spectrum as well as daylight around 6400 dK. I've made a couple of strip lights for my kids' aquariums using them and the plant growth was wonderful. I used a length of white plastic rain gutter, spray painted the outside black, added two end caps, screwed in a two bulb holder with a chain pull, screwed in the two bulbs and made a respectable looking and highly functional appliance for less than 10 bucks. Not counting the price of the bulbs, which run from $5 - $10 each - the full spectrum and daylight versions are available in gardening catalogs.

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....

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 |

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 |

I"m not sure who you're asking here, but it looks like you've got a pretty efficient plan right there - cost effective for sure - I wouldn't experiment on a project that sized - save the testing for a smaller tank or an existing incadescent strip. They're worth investigation, but not serious investing until you've given them a try on a small scale. Mr Gardener |

The rain gutter turns brown and brittle over time from the heat of the lamp. When I need to do this I use a standard black aquaruim hood made to take incandescents and scew in as many 23W daylight bulbs as I can (you can usually add a couple more byt adding another incandescent fitting. Keep in mind the refelctor in a fluorescent setup is going to give you almost half your light as it reflects the light that's otherwise waster because it's pointing the wrong direction (down, not up).

If you want Mylar just use old chip bags. They are made from Mylar & the
insides are reflective. "Larry Blanchard" wrote in message ... Mr. Gardener wrote: Yup. An effective reflector is always a challenge for me in my home made as well as store bought light holders.

If it's all you have, screwins are ok. Just. But you're not gonna light up a 120 with them unless you want the moral equivalent of LED moonlighting. We've oulived the T12 era and I'd only consuider compact flourescent, T5 or T8. T8's you can get a in a pinch at green home recycling centers, only buy ones with reaaly good angled polished aluminum reflectors, pass on any that have white reflectors. T5's I'd be surprised if you could find in places like this, but I did find a bunch of CF twin 40W fixtures last year (woo hoo!) so it could happen. 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. Yeah, I do that too. 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). Crappy tire sells a cheap 35 or 70W HPS(1) fixture and bulb. And an even cheaper mercury one. I'm just sayin.. Chose something that uses cheap (ie theres lots of them made) tubes. Color is personal taste - warm whiteif you prefer red, daylight if you prefer blue. I like the look of C50's and grolux but I'm not convinced they have any effect on plant growth whatsoever. (1) 12000 lumens from 70W or something like that. A 40W tube is about 3000 lumens. T8 or T12 or CF. -- Need Mercedes parts ? - http://parts.mbz.org Richard Sexton | Mercedes stuff: http://mbz.org 1970 280SE, 72 280SE | Home page: http://rs79.vrx.net 633CSi 250SE/C 300SD | http://aquaria.net http://killi.net |

Missed a bunch of the threads on this topic, but I assume your looking for a reflector.....how about the acrylic mirrow stuff. I use it under the hoods I make for my sal****er tanks and it lasts just fine. I line the hoods with this material which is pretty darn cheap to buy.......just get the el cheapo mirrows that wal mart sells for under $10.00 that are normally 12" x 48" that hang on a door or wall. Just make sure its acrylic and not golass which is pretty easy to do just by the weight of it alone you can tell. I have used a heap of this stuff over the years in a marine enviro. Another good source is a mylar film called monokote which is available as a heat shrink or as a pressure sensitive adhesive backed film, and is available in most hobby shops that sell RC airplane stuff. I have used it as well and it holds up to quite high wattage and heat of power compact bulbs just fine. YOu can get it in assorted colors or very shiney chrome metallic.....in sizes of about 36 inches x 6 inches or so...

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. I understand the difference. I got a bunch of the straight tube screw ins 15 years ago. They were ok but I eventually replaced them with conventional tubes. Can't say the last time I saw one now, they're all sporal screw ins. 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.

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. They do generate some heat so a fan and heat sink is best used, but thier color spectrum and intensity is far above any of the typical LEDS. You can mix various colors to get the effects your looking for. 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 ! Koi-ahoi mates.... I'm off to research. hmmmm 45 to 190 lumens per watt *impressive*. These look very interesting. Stainless steel hood would make a good heatsink... a trio of low voltage constant current sources in the tank stand, and some passive heat baffles in the canopy. I wonder if I would even need a glass cover? If the Luxeons use solid state technology, then I might just epoxy-coat the exposed connections. Humidity should not condense on their warmer surfaces, and if I have no aeration causing air bubbles to pop at the surface (slowly coating the inside of the canopy with calcium), then the installation should be quite reliable, efficient and cost effective. :o) Thanks Roy! -- www.NetMax.tk |
