Thank you for taking the time to reply

As you get a wide range in the low 400's up to 420n you have no concerns about "POP" there is masses of room to set what you want.

So I would get a similar "POP" as the Radions, have you seen both units side by side?

One of my main concerns about the Mitras is the lack of peak in the 405nm if you look at the Mitras spectrum graphs you posted after 415nm it dies off pretty quickly such that at 410nm there is almost nothing there.

comparing that to the radions you see much stronger 400-420nm range where as the Mitra is really 415-420 kind of range. This is most likely because they radions have 405nm specialized UV chips to cover that spectrum as well as 415nm LED.

I really think this is one place where the Mitras are lacking apart from that I think they are great lights. I suppose i could add additional UV led myself if needed but when paying so much for lights you kinda expect them to be good out the box.

But if these don't effect the POP from corals I could not care tbh and that is what I have been trying to find out. As I don't want to be lumped with dull looking lights like my T5. If they give me the same effect as the RADIONS then I will purchase one to start with and add second later.

YES everything is modular and client replaceable there is even a manual for this

thanks, does this mean in future we can do upgrade to our LED lights by replacing them like Vertex and radion allow their LED module to be upgraded.


I was also wondering what is GHL's serive like? What happens if the LED dies and i need replacement. If i only have one light unit and need to send it off for replacement I cant wait 3 weeks for repair all my corals will be dead. Would it possible to buy two units and run them on my Fluval Venezia 190 corner tank? Would that not be a TOO much light for such a small tank.


thank you for all the help you provided.

I've always been under the impression that it is the 420-450nm range that really make coral color 'pop'. Yes, 420 and down does make a coral fluoresce, like a pure actinic t5 bulb does, but it seems to me that it's a little higher on the nm scale that makes the 'pop'...
Lpspsclown, what exactly is 'uv mode' ? Which LEDs are lit in that mode?
Are you sure 'uv mode' only turns on the 405 and 415 on the Radion and not the next blue led which would (i assume) be around 450nm?
Just curious here..
I bet that if one were to turn down all the white, red, green, yellow and orange on the Mitras, it would provide the same 'pop'
Now, having not seen either of these lights in an 'all blue' mode, I am only speculating..

 

[AQD_ottawa]

The hyper violet and blues on the Mitras are insane, yes there are more blue fixtures out there but how far do you want to go before you completely detract from a natural spectrum found in the ocean.

The GHL lamp is designed to be as close to that as possible.

There has not been a single negative review or post on the Mitras to date in 6 months, so something must be right

Questions about the Mitra

Questions about the Mitra

Hi all,

I have two questions about the Mitra which I need to consult the experts here.

1. On the LCD panel, on the bottom row extreme right, there is a circle 'O' on the display, can any one tell me what does it mean?

2. At night when the Mitra is completely off, how do I turn on the lights if I need to take a quick look at the tank?

Thanks for your help!

1. O = moon phase it will change depending on the moon
2. = manual override

for number 2, you just go to manual over ride as Michael said and then you can control each LED individually, so if you just want to take a look at whats going on maybe put warm white up to 20% and your good to go! This is one of the greatest things about this light over all of the other leds out there!

 

[Cedric]

Thank you so much AQD ottawa and Clownin Aroun!

One more question, after going to the manual override to up the LED individually to take a look at the tank, how do I bring it back to the "automatic" mode?

I can tell you that the fluorescence from the two actinic LED's (405nm + 415nm) is amazing! I havent seen or compared to the MITRAS.

I've always been under the impression that it is the 420-450nm range that really make coral color 'pop'. Yes, 420 and down does make a coral fluoresce, like a pure actinic t5 bulb does, but it seems to me that it's a little higher on the nm scale that makes the 'pop'...

The Radion Pro has a separate channel for the linked (405+415nm) LEDs. No other blue is on this channel and this channel by itself like I said is amazing.

I have no idea if the same fluorescence is exhibited by the Mitras with its 420nm LED.

Just click the x once or twice

Just click the x once or twice

Thank you once again!

 

[reefmutt]

Gonna try this.. Haven't uploaded photos in a while and using mobile app..

Strawberry shortcake under the Mitras.

Had to... Soon, it'll be the real thing..

 

[AQD_ottawa]

:lmao::dance::lol:

 

[reefmutt]

Got a question, once they are in master and slave mode will I need to do software upgrades in each unit or can I just do it to the master?

 

[Haxer]

You have to upgrade the Firmware on each unit seperatly... Trust me I tried to only do the master first... I have three units as well...

haha Cute!

 

[reefmutt]

Thanks hexer..
I'll get on that..

 

[reefmutt]

If anybody's interested, here's how I hung them

The brackets are to the sides and the rack that the Mitras are attached to can slide back and forth for access to the tank..
Here's one unit. I just drilled holes in two sets of aluminum 'L' rod and then screwed in the supplies hanging kit..

I can move them
Back and forth when I am working in the tank..

Looks awesome but i really dont think you needed three! lol

You could blind yourself with all of those!!!

 

[reefmutt]

Didn't need three??? WHO doesn't need three!?
I must confess that is is probably overkill, but to explain my rational, I am a very firm believer in multiple point sources for lighting.... And flow, for that matter, but that's another story.. I got three so that I could minimize shadowing and really spread out full, good quality lighting throughout the tank. It's going to strictly sps and I'll probably be adding acros in every corner of the tank..it's been two years since I had a tank and I have no doubt that the addiction will hit fast and hard once I'm ready to add coral..
