Has any one bought these?

Just curious how well they work. Anyone have experience with them yet?

It says the smallest has six 1 watt bulbs...that doesn't seem like nearly enough to grow anything, right? javascript:popupWin1('/product/deta...2409-52995-52996-fish.jpg', 50, 50, 596, 380)

I'm interested in it, too. The LEDs are supposed to last for 3 years. What I don't know is whether one can replace the LEDs later.

I'd imagine they're just for general aquariums that don't have plants, coral, etc.

good call vamp, just in lumens 450 lumens is equal to about 8w of cfl, but led par tends to be higher, so maybe 10w of cfl? throw in that its directional, i wouldnt say its anymore than a 18 inch t8, maybe low light plants, im definateley overexaggerating the amount of light too

Yeah, that's about what I thought. I've heard of people using LED's on planted tanks, but a lot more than 6...

 

[DoctaQ]

o 6 on a planted could do, depends on the size though, i plan on putting 6 on my 20 gal in my signature, but the leds are going to be much more powerful each one is going to put out 75% as much light as this whole fixture

How does the calculation work with LED's? Like with CFL, it's the actual wattage you go by. Is there some trick to figuring out LED's?

It seems like that fixture is very pricy for it's output.

 

[DoctaQ]

for freshwater its something that im still trying to figure out.
theres a recent post by a guy named nova i think he put 12 leds on a 55gal and looks like crazy growth.

depending on the driver that you use to power the leds which seem to power 6 or 12 leds for the most part you think in multiples of that. seems like 6 leds can cover 2ish feet by a foot but the guy said he did have dimmer spots on the sides of his tank.

I just recently bought some of these for my low light tanks. They produce very bright light as compared to my flourescents. It is perfect I think for my 20 long. I'm worried about the depth of my 20 tall though. It doesn't penetrate as well. Too early yet to know...it's been about 8 days. The plants are not suffering, they all look good. Just don't know what growth I'll have. The look is nice though and they are cool running that is for sure!!

keep us posted id be interested, there isnt a lot of leds out there, and just about none for non-reef
