Well I have another question the instructions is lacking and maybe im not used to the fancy light. The lights coming on at 7am and I cant for the life of me figure out how to load a light setting or change it.

When you get it connect to the control center, go into the light composer. load up a default profile, pick the time that you want to modify, select color temp, and intensity.

once all change to your liking, upload it to the mitras.

oh really that easy let me go try that/

So it's been 4-5 months since I turned the Mitras on. I think there are at least a few updates I have to do... Since I have two Mitras do I update one at a time or can I wire one in and it will auto update the other at the same time?

Thanks.

I am planning on a 36x36x24 tank, would one mitra be enough spread ?

Need to be updated one at a time by direct USB connection

I have one on a 36x32x24 and I have light overspill ;) You will have good coverage at that size.

Hint - when setting schedule make sure you have a 0% intensity stop time and a 0% intensity start time unless you want the lamp on all night

for example

11pm - 0% intensity - 14k temp
7am - 0% intensity - 14k temp

Two reasons

1. Using older software (the firmware is embedded into the software)
2. You missed a step when doing the firmware update, i.e not power cycling the lamp after the update is finished)

Hint - Windows has a habit of overlapping USB ports so sometimes when you plug a USB device in it will not connect due to a conflict - blame windows :( and dont shoot the messenger either ;) Simply remove the USB cable, wait a few moments, reconnect and keep your fingers crossed. If it still wont connect make sure windows has not run off with the COM port, go to device manager and make sure the COM port is still the same.

Further support on this topic by me or GHL can be answered by posting here www.profiluxsupport.com

thanks Mike

Please find below a very easy to follow step by step guide to the GHL Mitras LED light composer

http://youtu.be/-7txuIXMdB4

we created a new driver for the Mitras, this driver has a signature and the Win 8 problems should disappear with this

the new driver is included in the new GHL Control Center, version 1.0.3.0, available for download from today on

-> please install the new GCC
http://forum.aquariumcomputer.com/do...?do=file&id=96

and include the new driver when connecting the lamp

ok i have another question it seems that my lights are not very bright. i have them on 50% for lights and the intensity is at 50-58% should i up them to a higher dose in the intensity

Be very careful the Mitras has a very balanced spectrum, as you move one slider you will see others rise and fall. Intensity is only a small part of the equation.

If you feel it is not bright enough then raise the brightness.

What does it mean if the 'X' on the control panel is flashing?

it means to upgrade your software and firmware to the latest version.

ok Im really getting ****ed with this light. 2 computers and still it wont up grade and load the darn drivers I have followed the instructions and still nothing.
I have down loaded the GHl Center and loaded it and down loaded the latest drivers and still its telling me its not loaded and can not find the drivers.

for suck a fancy light its sure being a RPITA

as I have said before if you are stuck then get support instead of ranting frustration it does not get us anywhere in helping you, which them just leads to more furstration for all concerned.

The win8 issue is not a mitras issue however if you join the support forum then you can get access to the latest patches which are not available here, until then its hard to give proper support.

please join www.profiluxsupport.com then we can help you out and get up and running.

But yes win8 is a PITA and I doubt 8.1 will be much better, I cnat even get my sony camera to connect through it.

Ok my right arrow stays flashing is there something wrong with it

Well i would like to ask here first before making the trekk over to the other board. because maybe some people on here may have has had this happen to them. So they would chime in before i head over to the other board.

Hi

3 firmware versions ago had a small bug that made the touch keys too sensitive this was addressed in a few firmware versions back, so you just need to update your firmware.

This is all covered on the support forum, I do suggest all Mitras owners sign up to the support forum so they have access to all the latest info including tyhe newly released firmware this week

Mike, did you get it going?
I have a new Windows 8 laptop and just got the firmware updated on my Mitras.
Let me know if I can help.

thanks Mitch I really appreciate it. ya shoot me a pm and I will call you after supper tomorrow ok.

thanks again

hi, I just downloaed the latest firmware on my Mitras and my new 93 gallon has just started cycling.
- Do i need to download any pre-configured programs.
- Should i be starting my Mitras during the Cycling stage.

Any help is much appreciated.

no you can start a template from scratch or cheat and email me for mine ;) info@ghlna.com

always best to start as you go on so yes start now.

Thanks Michael. So that means I shud start the LEDs during cycling stage now. Any help how many hours and what color/ intensity I shud be keeping it on .

around 50% and normal hours you would a light.

Many thanks..

Question - what height are people running theirs at over the water surface?

We run ours @ 14.5" above the surface but I doubt that is the recommended height.

https://dl.dropboxusercontent.com/u/...com/height.jpg

Oh wow.

The reason I ask is I'm running mine at 6" above the surface, but after 2 months with them, I'm starting to notice colour loss in a lot of SPS (getting way more pastel-ish in colour - polyps have colour but white in between the polyps). Am I running mine too low? I put in 3 Mitras, each replacing a 400W Radiums on lumenarc reflectors.

I would just dial back the overall intensity. There is no reason to move them up unless you want more light spread.

I'm running my around 12" off the water surface, but I'm also trying to determine if the LEDs are what is causing my SPS to constantly die. So I've raised them up and dial them down in overall intensity.

The units have significant power, if you are losing colour then lower the intensity. I run mine at 80% but only for 2 hours during the peak. 12" above the water.

I cant imagine die off has anything to do with a lamp, the coral would go white due to high intensity before dying and would not be quick.

There's no die off (at least not yet), just loss of colour saturation.

I'll try adjusting the programming and lowering the intensity. Sounds like it could be too bright / too close (at least I'm not running at the higher intensity settings!).

I have mine 7 inches above waterline and I find corals on the higher end of the rocks are encrusting and growing better then ones placed lower. Colors are excellent, no colors fading or dying off. With that being said, these corals are sps and I would not place LPS or softies high. I now run 100% intensity for I think 3-4 hrs and I also have a lot of flow in my tank which I think helps as well.

I've done two things recently even tho you're only supposed to make one change at a time.

- raised the lights a bit each day so the wife doesn't notice. initially she said the light bleed to her spot on the couch was a problem but i did this a while ago without her noticing. now i'm probably 8 or 9 inches off the water and plan to eventually hit 12" or so.

- dropped both my cool white and neutral white by a lot. trying a more blue spectrum to see how things react. i reduced their output a lot while also turning the overall power from 60% to 100%. my tank looks a bit brighter but the corals are probably getting the same or a little less light than before (higher up, less white more blue).

so far so good. my tank was crazy pale and i had a few sps start to go which has never happened to me before.

as i mentioned last night tho tony i've also started feeding heavier too.

This could be a great scientific study. Do you know what this could mean for man kind if she doesn't notice that much of an increase in height considering her previous complaints? It's proving a theory we could all only dream about.

Just a little Fyi
