The Weipro light looks to be made of extremely low wattage LED lights. The LED fixtures usually have 3W leds. Any lower is not enough to grow corals.
Actually, in my reading I came across an article that said it didn't matter whether it was 1W or 3W. The only difference being that it required more 1W LEDs to get the same coverage as the 3W. The article basically said something to the effect of each area should receive light from 7-8 1W LEDs vs. a single 3W LED.
Whether or not this is true, I don't know for sure. I think the only way we would find out for sure is to get someone to take some PAR readings - even though I must admit I still don't know what PAR actually is - unless it's photosynthesizable(is that even a word?) light.
The other reason I started this thread is because there are so many people who insist that certain LEDs are unable to sustain corals, while others say it's not a problem. Their statements are based off someone else telling them it will or won't work, but as so many have pointed out to me, this technology is still in it's "infancy".
That being said, I opened this thread in hopes that someone had experience with some of these LEDs - especially the more economically priced ones. While I must admit, I do like the idea of being able to control the cycles from a program, I also must contend with the fact that I am on somewhat of a budget - as I'm sure others are too. And I'm quite positive that there are others out there that wish they could grow corals in their tank using a less expensive alternative light source that uses less energy and doesn't generate heat, which must then be removed.
In response to this, I pose a suggestion:
If you are in the market, visit your LFS - ask if they have any LED tanks - if not encourage them to start one. Lets face it - a LFS has the ability moreso that most to sustain an LED only test tank and report the results.
Phenom, no offense to you, you just helped shove the soapbox under me
. I'll step down now.
