    Thanks for that link I will read it in just a moment.

    You don't need to be a millionaire to get LED's, I just stuff junk mail for my daily bread. I got a set of seven bulbs for $260 including shipping off ebay from the Manufacturer (which are guarenteed to work like new for 10 years or send back for free replacement). The only local Hydroponics / indoor gardening store wants over a thousand dollars for a prebuilt setup with the same number of bulbs. I just got bulbs so I have to build a light hood or set up two tracks of track lighting to mount the 5" x 5" bulbs but I like building stuff and they use normal household lamp sockets. Not payng anything for running them and still growing "like MH or HPS" is what made me decide to splurge. It's funny to think that the fresh air fan and humidifier on the terrarium will now cost more to run than the lamps!

    They do look real weird in the photos (mine haven't arrived yet). I read what i could find online but I still don't "get" how I could possibly grow plants with such an aparently dim light source as I'm used to thinking about lumens and watts and intensity of light on leaves.

    i'm a bit skeptical about 14 watts generating enough light for plants to grow. Even though it is in the spectrum plants use, it's still hard to believe.
    Not to mention the cost is pretty outrageous. I think that the t-5 high output fluorescent lights would be a better investment.
    If these bulbs truly did what they said, wouldn't there be more people growing, and talking about it?

    Look at the coral! The hood is nice to, except for the control panel on the front. They should have put it on the back.

    That is some MAJOR cash right there. $849 for a 14 inch model.

    If you have a 6 foot tank, prepare to shell out over 3 grand

    After reading some of the research on the application of LEDs to plant cultivation, I'm very interested. The low operation and maintenance costs have me sold. I saw some conversion bulbs on eBay for a modest price - they screw into standard incandescent fixtures and look kind of like showerheads - and I think I'll pick some of those up the next time I'm looking to add to my lighting setup. 12 bulbs for $160 is a little steep, but supposedly four bulbs will light something like a 4' x 3' space for 10+ years, and at less than 14 watts per bulb, that's a pretty much unbeatable deal when you factor in energy consumption. I'd like to add them in to supplement my T12s, and then maybe phase out the fluorescent light if things go well. I'm excited to hear what results people have if they try these.

    When you're looking for LEDs look for lamps with the highest number of LEDs per bulb, most of the ones I've seen only have 40-80 LEDs per bulb. The ones I've got coming have 160 or more LEDs inside each bulb. Definately go with DIY screw in type ones way cheaper than some fancy schmancy factory made parts save that $ buy more plants (or coral).

    Swords please document your experiences and experiments when you get them. I would like to see someone grow two plants from seed. One with traditional lighting and the other with the LEDs and compair the growth. If growth is about the same then I would be sold! The less need for cooling and less power used is a definate plus.

    That's what most people said about modern science. In 50 years I bet NOBODY will be using incandescents anymore (assuming we're all still alive and survive global warming and all that).

    I got my lamps and bases a few weeks ago but I haven't gotten all set up with them yet though. The ones I got are pretty neat, like a stop light that's really bright. I tested them by just putting them in a table lamp socket and it shot a beam of colored light all the way up to my vaulted ceiling some 15 feet up. The photos used on the site I got mine from ( http://www.gro-tek.com ) sure don't do the lamps justice. That still don't mean they'll grow plants (or corals) but if they do, I'm definatley gonna use them over any other type. $260 to light 12 sq foot of growing space for 10 years - I'm sold! But we'll see!
    I will be documenting my experiences with them (both setting up and growing with them) on my grow info site www.captivejungle.com and on terraforums too of course!
