Thank you. Looks like a great light.

Btompkin · 10/04/2012, 09:44 PM

Thanks for info
Can't wait for mine to arrive.

Congrats Rodney!

What do you think about the software? What about how the lights dim?

What are the dimensions of your tank? I'm thinking about how I would mount the lights. The way you have yours would make for a single rail and an easier mounting to the ceiling. The other way (display facing front of tank) might work as well.

Please keep us posted on how your corals respond to the Mitras compared to the Ai Sol Blues.

Thanks for posting your thoughts.

rodneyri · 10/05/2012, 04:01 AM

mounted the lights tonight, this is the rail i came up with until GHL have a nice one

BigAl2007 · 10/05/2012, 05:53 AM

Great looking set-up!!

aandfsoccr04 · 10/05/2012, 08:30 AM

wow that tank looks clean.

I agree. That's a VERY sharp looking tank!

Rodney- what are the dimensions of that tank? Looks great by the way.

AQD_ottawa · 10/05/2012, 10:38 AM

I was told it is 140x75x55 which translates to 56" x 30" x 22"

madean · 10/05/2012, 10:50 AM

From the looks of it, I would say that I need 2 fixtures for my 36"L x 30"W x 24"H tank build. I was hoping to get away with 1 unit.
Rodney- at what intensity are you powering your lights at?

Just want to say thanks for all of those who take the time to answer others questions.

AQD_ottawa · 10/05/2012, 11:06 AM

The width as with all LED units is the conundrum. We are building a demo system right now that is 36x32x24 and will be using one lamp, this is outside the stated coverage at the bottom of the tank, but GHL always will only give accurate figures they feel are valid. We also only market to these figures, but we are interested in seeing cleints tanks that have been pushed beyond this.

A lot of it comes down to what you are wanting to keep, if you do not have SPS wall to wall you can potentially play with the configuration more.

rodneyri · 10/06/2012, 09:34 PM

Readings taken with an Apogee PAR meter, all pumps turned off in my tank. Tank had a water change yesterday. To keep the readings consistent I placed the meter's sensor in the tank and took a reading in High Efficiency mode on the Mitras then without moving the sensor changes the lights to High Output mode and took the reading. This was repeated at each level so the results are comparable with my situation.

Tank Specs; 140x75x55 deep (water level approx 57)

PAR readings in High Efficiency mode
240 (sandbed)
312
368
576 (water level)

PAR readings in High Output mode
340 (sandbed)
450
560
810 (water level)

madean · 10/06/2012, 11:27 PM

rodney- could you take readings on the left fixture all the way to the left wall of your aquarium just to see what the readings are away from directly underneath the light. Or better yeat could you only turn on the middle light and read away from dead center lets say in 5 inch increments and post the reading on the sand bed. I think seeing the par readings to the left and right of dead center are valuable information for people to decide how many units they will need for their specific aquariums. Again thanks for posting this information.

rodneyri · 10/06/2012, 11:53 PM

Just took readings with one Mitras on, starting from in the middle directly under the light and moving 10cm away each time. All readings on sandbed.

PAR at the glass was 196. Only measured this in the centre position.

AQD_ottawa · 10/07/2012, 06:16 AM

These are seriously amazing readings! the useable spread is wide by any standard!

loup · 10/07/2012, 09:33 AM

That coverage for a unit is huge. Simply amazing. Those par reading are nice.

ooja3k · 10/07/2012, 01:19 PM

What are the thougts on one unit over a 36" long x 18" wide x 21" tall...

Will this provide enough spread and usable light for sps?

AQD_ottawa · 10/07/2012, 02:06 PM

This does depend on your rock work and also the location of the SPS, 36" is still an untested length but based on the above PAR readings the outcome is highly encouraging.

madean · 10/07/2012, 02:43 PM

rodney-I am assuming thats high efficiency mode and not high output mode. either way thats pretty impressiv since its on the short side of the light and not the long side. I gotta believe those numbers re even higher with the long side of the light and on the high output mode. this fixture is looking better and better for my situation.

rodney again thank you

madean · 10/07/2012, 02:53 PM

40 cm = 15 inches, so if I were to turn the light the other way compared to rodney's setup, I am looking at possibly getting 175ish par on the front and back panels of my 36"L x 30"W x 24"T tank. I know rodneys tank is 2" shorter than mine but I am sure to have more sand than he does which would put me at about the same depth on the top of the sand bed. I gotta imagine the par levels are going to be better on the long side of the fixture compared to the short side that rodney posted.

This light is really impressive. This is the type of information I think manufactures need to post. Even on an empty tank with no corals.

madean · 10/07/2012, 02:57 PM

I gotta imagine that in high output mode your getting over 200 par at 40cm/15" away from light.

rodneyri · 10/07/2012, 03:11 PM

oops forgot to put that in, the single light is tested in HIGH OUTPUT mode. All readings taken with LEDs on at 100% which I would never use for viewing.

AQD_ottawa · 10/07/2012, 03:27 PM

Rodney,

First I want to thank you personally for your evaluation, your insight has been incredibly helpful and very unbiased. So a big thank you.

In regards to coverage area, would you feel safe in saying the Mitras could cover a 36" long tank? (91cm) The official figures stop short at 32" (81cm) and this is the biggest question we are getting now.

I really appreciate your thought whether positive or negative.

rodneyri · 10/07/2012, 03:38 PM

Id think you could use a single Mitras over 36" tank, but I wouldnt put any SPS outside of a 24" diameter around the light, going under 200 PAR gets tricky with these corals, the aquascape would also have to be made suitable for a single light as when the corals grow they will block the light to the corals on the extremities. You could keep SPS concerntrated in the middle and have LPS / Zoas out to 36" no probs IMO.

If it were me, id get two units because I like the flexibility and wouldnt want to be restricting the location I can keep corals by lighting limitations.
