New to LED lighting

I am new to LED lighting. I have found some grow lights. But i dont know much about lumens or wavelength. These are the specs I have on the light im thinking about purchasing.. .
Blue LED Lumen5.55 Lux x 112 LEDs (621.5lux in total)White LED Lumen6.93 Lux x 113 LEDs (784lux in total)Blue LED Wavelength450nm
LEDs Diameter5mm
Is this enough for a 49 gallon reef tank?

Many thanks in advance

 

can you post a link to them?

 

Here it is on ebay. eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

 

I would not buy those! There's a reason people drop about $150 bare minimum to light up there tank of that size, and thats bare minimum and for a DIY build! And for 225 leds, that's weak output! Alot of issues there, not even sure it would keep a plant alive! Sorry, just alot wrong with that for a reef! Maybe for fish only tank, but even then, you really don't know much about those lights!

 

Thanks. All descriptions of LED lights are very vague. I dont understand lumens. With MH and compact flos. Watts per gallon. Is there any site to explain it to me?

 

I've heard in some people's review for this light panel that their plants are dying under them, You can do an experiment to prove that to you, but it's not worth it, most likely ur corals will die,, even softies.

 

A very basic guide most respected sponsors seem to put out is 20 3 watt Cree leds per a 2'x2' area! Heres some good reading!

+1 to above statements, I am taking the LED plunge as well, and want to do it right! make sure you really do your home work, I have been researching for about 1 1/2 months to find the right led at the best price. DIY will probably be the cheapest route, and if you buy things like modular led kits, where they are solderless, you can always add on or take off you know?

 

10 frag tank

Would this light be ok for a 10 frag aquarium?
