Show Us Your LED Tanks

[Dearth]

I believe the stigma of deep water lighting is a hold over from when LEDs first came out and even though LEDs have been out for several years now you still meet a lot of people who have the doubts that the lights can do as advertised so live with the idea LEDs will not light the bottom of the tank sufficiently even with evidence to the contrary. Then most LFS don't actually carry the good quality lights which enforces in people's minds their rational behind not enough lighting. As a guy who started out in fresh water where lighting was not critical component of the system I count myself as fortunate when I started off in SW I started off with LEDs and don't have the same prejudices as others who used MH and T5s before LEDs came out.

Here is a video from a customer who put a couple LEDs above his 6 foot 130G tank.

Of course you can easily go up in cost from there to the Mitras at $1200 (retail) per unit. Not everyone needs a $1200 Mitras though. There are plenty of people (as we've seen in this thread) doing quite well with their $400 AI Sols :-)

Keep in mind you'll need 2 sols for 1 Mitra so really comparing $800 to $1200 which isn't as big of a gap. Then when you compare features like built in controller, full spectrum and so on you may conclude the Mitra is also pretty reasonable

There are lower cost units that get the job done but ultimately you're getting what you paid for. Like the D120s, I had to open the fixture up to change the power cord orientation. Doing so I discovered it's basically just a thin aluminium plate with LEDs directly mounted to that, wired to two basic power supplies with a dimmer and three noisy cheap fans. Pretty obvious why they are so cheap but they do work and whatever I put under them seems to do really well but it's a shallow tank so the output is really low, not sure I'd trust the cooling capabilities at full power.

Yes, it's definitely reasonable if you need all of those features. Not everyone needs all those bells and whistles though. As demonstrated in this thread, there are lots of nice tanks running LED lights without any controllers or full spectrum. I'm not about to tell those people that they need more expensive Mitras :-)

And yes, if you want the same output as a Mitras, then you will have to add additional (cheaper units). But then again, not everyone needs the kind of output that the Mitras provides. There are people dialing down the output of LED units that have less maximum output than the Mitras.

Once I save up the coinage I will be switching to LEDs on my big tank but that will be awhile in coming.

My tank is 30" deep. I would consider that as being a deep tank. I grow SPS quite well on the sandbed. I cannot have any chalice nor other LPS directly under them as they will bleach. I do run at 100% for a couple of hours each day though. So the info you are reading is not correct.

I have this 30 gal with LED since 2008. I can only grow soft corals.

well may I ask what kind

Finally got all the glass clean. So it's somewhat presentable now. Lol

This is how I set up my AI's @ 12" above the water and still reaches to the bottom with no problem, Whites, blues and royal blues can't remember what % they were set at, but were nowhere full power. I was just on a learning curve with them. Best lights I've ever had, no problems so far.
