I still think there is "something" missing with LED but that's a whole other conversation and light coverage is definitely a big part of it. Meanwhile though, I would still go mh/t5/vho and let others continue to figure out LED.

Can you even still get a fixture with VHO these days other than maybe finding ballasts, end caps and bulbs and building one? I have an old Hamilton MH 48" out in the garage that has VHO's and I always loved them. I just made a comment the other day about T5 actinic just not pulling the pop of VHO. I hate when new and improved things are actually less useful than what they replace. Neither T5 or PC ever lived up to VHO and LED has not lived up to MH.

Get yourself a 6 bulb ati t5 fixture. Remove the 2 middle bulbs. Cut 2 circles. Insert kessil A360s. Done ;-)

The best light is the one you like the most. Opinions on lighting are all over the place and some people have very strong opinions on various systems. Lighting is just one part of what it takes to have healthy colorful corals. All systems have pros and cons you have to account for during operation.
Once you talk high end fixtures it is just personal preference across system.

Good post, Also many blame the LEDs when they have issues, and most of the time it is not the LEDs that is causing the issue.
I have had almost every light unit possible and find most LEDs work well over corals. Most of the problems seems to be that people are putting too much light over there tanks and wondering why there corals are not doing well. |

I agree I've even made the same mistake just coral don't like the change and then people blast there whites super high and then wonder why everything is stressing. I have the hydra52 and I must say starting dim and working your way up the sps are getting colors I have not see with my old Kessil lighting for 2 years But I'll running t5 on the 120 since cost is about the same.

I've never seen the pacific sun in person. The ati looks amazing to me. I'm a t5 person though and the LED's add a little something extra to the picture. Quality of the fixture aside (best by far IMHO) the light it produces is incredible.

These are all great ideas and great systems. However, nothing takes the place of doing some reading of empirical data. Start with Sanjay's info at http://www.manhattanreefs.com/lighting. Then make a decision that suits your particular tank, needs, and wants.

Thank you all for the suggestions. I don't mind mh but living in houston, heat is an issue. I have a chiller that operates a lot during the day. I will look at the ati hybrid setup. If anyone knows a place to get them discounted, let me know.

Again, go out and look at some. You will not find anything on the interwebs that will help you as much as your own eyes and meeting some people - you cannot get depth, breadth and perspective from a computer screen.

ATI T5 fixture IMO. T5 are the best for growing SPS.
An ATI Powermodule all T5 Unit was one of if not the best fixture for growing SPS corals.

At the reef raft store in the Bay Area, all the sps are under ati t5 fixtures

The shading comments have to do with the UNDERNEATH of the corals, not one coral shading another coral. LEDs are terrible for light wrap because they are a pinpoint light source. So you end up with the top surface of your coral having color and PE, but the bottoms are completely bare and colorless. I think LEDs have their place, they are just not the BEST option right now. This thread is about the BEST, with zero financial constraints. Some have mentioned LED units that fully cover the top of the tank, rather than spot lights and this would definitely help.

In a no budget scenario, a pure LED fixture is not the best, period. I did however recommend the ATI LED/T5 hybrid though. The color "pop" of LED is second to none so with the LEDs supplementing the T5 (or the other way around) you will have a well rounded fixture. Edit: In fact, this thread of yours exemplifies the issue with LED shading: http://www.reefcentral.com/forums/sh....php?t=2414300. Quote:

I'm not disputing that LEDs work, but I too would drop MH and sing praises of radions if BRS gave me free radions to do a marketing video

You get shading with almost all light sources under colonies but it's just more pronounced with led only systems without overdoing it fixture wise imo. I totally agree that leds are capable of growing coral I just don't feel they are the best sole light source available at this time.
