How Many Mitras?
 

Hey folks, I've been considering upgrading my lights, presently on a 6'x3'x27" tank I have 8 radion Gen1s with the TIR lenses. I probably only needed 6 lighs, but at the time I was planning this, I didn't trust LEDs that much, and wanted to have too much light as opposed to too little. As a result, I can't run my lights any higher than 75% max intensity.

How many Mitras's would I need to cover the same space, and still be able to grow SPS on the sand-bed (which is about 25" down)

3 units should do you the spread we are seeing is 36x32 budget for 4 but start with 3.

Here is one on a 36x32x24

The shading at the back is clearly the shadowing from the rock work at the back, the light is center hung of course.

thats at about 50% intensity at just under 14k

3 should be fine I firmly believe I could have done my 225g with just 2 but here is perfect

3 parallel or 4 perpendicular. 3 would be enough but if 4 is in the budget then that's what I would recommend especially since you're running 8 radions @ 75%, 3 Mitras simply won't match that much light.

To get similar coverage, I'd say 6. But it really depends on how your rock is spread out. Mitras have a sick spread and amazing spectrum, but you will still have some shading with a center point over your tank. Spread it out to 3 lights (length wise) on the front and 3 on the back and your set. Getting light on the viewing side of the corals makes a huge difference.

6 would be great but I strongly suggest starting with 3-4 I have seen so many people buy more and end up with too many.

There could be a black market from the over purchasers :)

You must have missed the part where he said he is currently running 8 Radions. :-D

If it were me I would put 4 (perpendicular) over my tank.

6 is ridiculous for that size tank. Even with 3 you won't have any shaded spots.

I have had a Mitra over my tank with very similar dimensions 72X36X27, and to eliminate any dark spot in the tank I guarantee you will be looking at 6 units.
