Need MH Reflectors for SPS dominate 180 gallon 6x2x2

[ff337]

After doing some research I need some personal opinions/facts for reflectors that would fit my application. Pictures welcome, with mounting heights etc.

180 gallon 6x2x2. Canopy is approximately 16" tall. I can not go any higher due to the ceiling restriction (3) 400 watt 20k radiums with T5VHO actinics. I might use LED stunners for actinics, undecided.

I would like uniform spread with superb par ratings without cone shaped shadows.

I have looked at Lumenbright mini's. From what I read, they need to be atleast 16" or so above the water for uniform spread.

Also, clarify. From what I have been researching all par readings are done at 24" and 30" for tank depths. What height are these fixtures mounted? Most do not specify.

Thank you for reading and your help.

I've always read the Lumenarcs have better spread and less spotlighting, but I think we've already had that conversation, lol.

I have the lumenbright mini wides over my 120. I like them a lot. Very good spread for a 2x2 setup. I am running 250s though and i don't know what the par is. I will say that its a sps tank and they're growing very well. I agree with ryan too the lumenarcs are awesome reflectors. Lumenmax elites are pretty sweet too. My buddy had those over a 90 gallon and i liked them a lot. Good luck

The spread is fine with most of the reflectors. Par is decent on all of them. My application will need to be specific due to height restraints. I am limited with distance from water to top of canopy. 16"

Please list how high they are mounted.
