Not quite sure where you got that info but I found alot of research that contradicts that to the extreme. Really it's the exact opposite. And I agree they are not worth the money right now but I did happen to have extra money.
I got some of it from advanced aquarist and some other people in the industry who Solaris sent their product to for testing. Other then from Solaris, where have you gotten your information? I've seen the Solaris LED in person many times and what bothers me more then anything is that it just doesn't look as good as MH...a lot less natural and for that kind of money it should blow anything else away and the only area it does is with controls and effiencency (but really, is 40% or what ever they claim enough to justify the price)?
Granted, I looked into this early last year and over the past 12-14 months their may have been improvements in the technology. I'm curious to see wher LED technology will go in the next couple of years but right now LED is best used a suppliment to MH as a moonlight.

Acually I ahve got none of my info from solaris or solaris sponsered sites however mos tof the research is on sites sposered by competitors to swf.com.
"I'm curious to see wher LED technology will go in the next couple of years but right now LED is best used a suppliment to MH as a moonlight"
Yes but as in 3-4 LED's this is like 12 high powered ones per square (there are 6 squares on a 72") However once again I agree there not worth the money.

Forgot this, I read somewhere that at the 2006-07 MACNA confernce, Sanjay (noted lighting guru) mentioned that LED's real par was more on level with PC not MH but in a few years could rival MH.

he said was on a level of t5s not PCs I was at the MACNA in pittsburgh but still your right less par than MH but not to far off in years to come they will be what everyone will run

I think a lot of people are interested to see where the technology will go in the coming years but I'd never say that everyone will run it.

no offense intended but im going to flat out disagree with you. I've seen my research you've seen yours. Each to their own I suppose.

well, one of you have to be right.
sanjay tends to have a lot of good information. hes a hobbyiest and he does the tests himself. he has no reason to fudge numbers
solaris on the other hand, is obviously trying to sell their product and get it out there.
i think you see where im going with this.

If you acually read my posts i said that solaris didn't do the research or sponsor it in anyway.. I checked that out. Also the tests were done on the first ones out in comparison to 250watts MH. Although 400+watt metal halide are probly more powerful, I wont disagree to that. But what I am saying is that LED's are atleast as powerful as the common MH's out there.

Where is this info, if you can post and site it I'd like to see. Also, I want to see the testing done with qaulity MH Bulbs (not low par bulbs), ballasts and reflectors...these make a big difference. I don't think you will come back with anything but if can find it please share.

who did the research that you feel is so accurate?

I will try to find all that information for you. Also, again, if you read post post you would know that other sites advertise on it so I can't just post a link.

 

[h3b]

before i go looking im just wondering if you know what the PAr level is for 150w 250w and 400w MH's... just wondering. And of course with proper reflectors and such.

 

[h3b]

found this qoute on another site from the admin:
"I just got back from an ARC meeting and Kevin (kj_yoda) was saying they put a PAR meter under this light and a MH 150w at MACNA, and the LED's had 3 times the amount of par. Very nice! I'm almost sold, but something tells me to wait until all the bugs are worked out."
i'll keep looking for a study that I can post though.

 

[teen]

yea because if your administration, you must be right.

150w DE or SE? what type of ballast? what bulb? what reflector?

i never said that if they are admin they are right , just less likely to lie.
DE i think and i dont know about the rest although as i have stated numerous times probably just regular run of the mill things that everyone has. but i cant prove it one way or another.

I don't have much to compare it to; noob. But I am using mine on the 180 tank I built and love it so far. No heat meant no chiller to try and fit into a cabinet that was already overcrowded. Here is a pic or 2. Tank is 3 months old I am am just starting to add corals.
That is a beautiful setup

wow, I never realised that LED's would be so controversial.

 

[seltzerd]

I know of at least 2 other companies coming out with LEDs. This will eventually lower the price, and the technology will get better as all light move towards LED in the rising age of limited resources
