hello from China

Dear friends,here is miya from China,this is my first time come here,i am looking forward to build friendship with you

Howdy. Welcome to the forums. You would win the "furthest away from East Texas" award... if we had that award anways! :-)

cheap china led lights?

Oooohhh... do I hear a suggestion of cynicism?
I just knew someone would be of the same opinion ;-]

Likely because of the "apollo 12" LEDs that were linked from our forum here.

did you buy some from China?so did you buy a cheap quality one,i feel sorry for your mistake,it seems you have make a poorly decision

Welcome to the forum Miya, tell us a little about yourself.. what kind of tank? Reef tank by your pic. Being on the otherside of the world, you must have different ways of doing things.. Always interested in seeing others set-ups

Miya, Matt is very cheap, which is why he makes his own lights, he taught Scrooge how to be tight-fisted. Rumour has it that he uses candles instead of LED's.

Yep. Too cheap to buy them though... got my own bee hives for the wax needed. Check it: http://www.beeswaxreeflighting.com/

i am a person interest in aquarium,but not the tank,i am interest in something else,i just use the tank for test, for,what can i do let the reef and coral,fish grow well and look more beatiful?just do much experience,and it is also my work to do this,but i am also interest in learning much of coral and reef and so on,may be i can learn more from someone in the forum

Miya,
What PAR do the lights you use give & what wattage are they?

aha, LED lights is not so easy as it seems,it involves so many factors to do LED lights,like circuit lines,ratio and so on,how can you Matt make by himself without testing and use candles intead of LED

i can open your link,but i feel sorry for your mistake,it seems you have make a worse decision,iso many people use them work very well

Apollo8:PAR 2000par---45cm远的距离， 120*3w

I was just joking. I'm not using candles. I am using LEDs. I also did just create my own fixture with meanwell drivers and Cree LEDs. It's gorgeous.

Also very strange to hear 2000par. That's way too much for corals and will burn the highest light corals... even acros. Unless of course the spectrum is off and the LEDs don't peak in the best spectrum... between 440 and 460nm.

strange?so do you think LED aquarium light just can make of 460nm and white,i also use red specturm for my light,because i have a tank with fresh water,so red specturm is necessary,this is what i measure in the air,and the ratio is 660nm:460nm:14000k,how can you measure the par under the water

miya wrote:strange?so do you think LED aquarium light just can make of 460nm and white

Yes. Very popular. The royal blue (~450nm) LEDs hit a great growth spot for both coral chlorophyll a & b. And since white light is created by combining all colors in the spectrum, red spectrum is produced by the white LEDs. Although, there is more red spectrum in natural white LEDs than cool white LEDs.

miya wrote:i also use red specturm for my light,because i have a tank with fresh water,so red specturm is necessary

No red spectrum is necessary to grow corals. In natural sea water the red spectrum is nearly non-existent below 10m, and is truly gone below 40m. Corals receive almost no red spectrum in their natural environment. Coral chlorophyll CAN grow under red spectrum, but so can algae. I would prefer to leave the red spectrum out and concentrate on the 450nm spectrum that corals can grow under and algae can't! Sadly any light that is "white" will HAVE to have some red in it... and algae is simple enough that even a little light is often enough light. :-)

You'd need to purchase an external sensor and make sure the sensor's housing is waterproof. Here's an article on par meters for reef tanks. http://www.advancedaquarist.com/2005/7/review

Typically measurements taken through air are more accurate to compare fixtures as once you go below water there are many factors that will change from tank to tank (light being bent by surface waves, water clarity... even algae on the glass will reduce it's reflectiveness).

i think you don't want me to go to bed,i will give nobel to you if i can,
if fact i have a red spetrum for coral,it works very good,red is non-exestent in the salt water,but i have tell before,i have a tank with fresh water,it is important for waterweeds and reef

Alrighty dokie. :-)

Hot dang, with threads like this who needs the funny papers

What city are you from? I know China well I believe.

我觉得这个语句在翻译中失去的东西。

I am sorry buddy, the sentence above is not correct one either.

Did you use GOOGLe ?

How did you even find this forum? Did you do a search for the smallest group of reefkeepers in one of the hardest areas to do it?
