Check out these specs please.

I am looking at a alternative system to the K3 dimmable unit. While there is cost savings this place is within a days drive from me and have been around for some time. There is some comfort in that it is locally built.

Whoa. That's a lot of LED! Plus you get reflectors. It looks like someone tried to mimic the Radion unit, somewhat similar in spectrum but with 2 watt bulbs. It's hard to tell with LEDs. I do like the 3 outlet capability for separate dusk/dawn effect. You will still need moonlights too. And keep in mind - those blues are of the higher blues in the spectrum. The royal blues sit at 443-445 nm.

Now the questions:

- Can you at least go and see what the lighting fixture looks like over a tank?
- The UV lighting is particularly there for SPS. I still don't know what type of corals you (plan to) keep.
- Out of curiosity, how much is a unit like that?

Again, I am really happy with my Ecoxotic LEDs. I can actually speak to those with a little more insight. In my imperfect, humble, honest and (kind of off the cuff) experience, this is probably better suited for an SPS dominant tank with a minimum of 24 inches depth. And I am no expert. Just some NYer who did a lot of research.

Just my two cents.

I can buy this unit for about 450.00 delivered. I thought it was worth the look. I have seen pics of the unit. It is white case with I think 3 cooling fans. Not bad looking if set over a modern style tank and stand. My stand and tank are stainless finished so I think that is no problem if this works.
The Key K3 is over 600.00 because of 127.00 shipping which got me looking again.

Everything looks ok on the numbers line. But what is the total Lumens of the unit, that will tell us how bright the actual unit is, and to what depth it will penetrate.

[chrisfont23]

UV though? You have to think someone had more than LPS in mind when they put this thing together. That is why I am (blindly) guessing a deep SPS dominant tank would do best w/ this lighting fixture.

I have emailed and asked for the lumens and par at 18 inches tank depth. Here are a few pics of the unit I lifted off there add. This unit is on sale during the holidays and only 4 left so I may make a purchase soon.

[ShooterRick]

Here are the par numbers: Compared to MH.

Depth: Type of lighting: Metal Halide
light to surface (15"): peak-400 avg-350
just under surface of water: peak-91 avg-80
12" under water: peak-87 avg-80
bottom of 55 gallon tank (19"): peak-47 avg-40

Depth: Type of lighting: LED
light to surface (15"): peak-700 avg-600
just under surface of water: peak-380 avg-375
12" under water: peak-250 avg-200
bottom of 55 gallon tank (19"): peak-175 avg-165

FWIW: samsreef.com - PAR readings - How much light?

[ShooterRick]

FWIW: samsreef.com - PAR readings - How much light?

Thanks. It seems this unit is about on the money if I am reading the charts correctly. I just purchased one of these a few minutes ago and will report what I find at a later date. Since it has the ability to run at dimmed levels I think too much light will not be a problem.

There ya have it folks.
Those #'s look good to me. I give em two thumbs up.

When you get it, shoot me the Lumens that it says it has. With that many freakin LED's I'd have thought it would be higher on the PAR values.

Me too

[Reefing Madness]

Me too

Looking to compare it to a Reef unit with @ 48" and 54 LED's has a Lumen of 3340. Curious to see how those pan out.

[ShooterRick]

Will do guys. Remember also those par readings were taken with the fixture 15 inches above water surface. Seems to me in the many pics I have seen of lights over tanks they are getting mounted at about half that distance. I could be wrong of course as pics can be misleading.

Yea, I hear ya. Normal mounts are like 6-10" above.

[ShooterRick]

I thought so. Must of been because they were drawing a comp to MH lighting. I would assume because of the heat MH are mounted higher but that is just a guess on my part.

Got me, my Halides are mounted 8" off the water.

Just got an email update. Unit shipped today from Daytona FL. Should be here this week. The brand name of the fixture is Coral Maxx. It is sold by a physical store in Daytona through there web location at purelyh3o.com. I like that they have a physical location in the U.S. I think they have 3 of this model left on year end close out. Their price on ebay is better than their web store.

First Impressions of this unit I recieved tonight:
First this is going to be a incomplete review as I am beat from work leading up to the holidays. I will provide more detail and photos this weekend.

The unit came packed well. While I was expecting a white powder coated fixture, black is what was sent. I prefer the black case so not a big deal to me but during the year end sale color was not specified and the pics were white. Since they only had 4 of these on sale I assume you get what you get. The fixture is manufactured by purlyH2o.com based in Datona Florida. The control unit which runs the light and its various settings is clearly marked "made in China".

For some the control box would take some getting use to. It is formatted in military time and being an old USAF non com, this isn't an issue for me. The timer is 3 channels controlling all 3 circuits mentioned above as to time on and off and days of the week. The LCD display is reasonably large and easy to read.

Documentation with the unit is limited at best. Ample instructions are there for the control unit but while the par values mentioned above are available other data like Lumens is not. Over all for the price of 449.00 this unit is promising for 180 watt LED. I will provide more info and show some pics later as mentioned.

Supper is done and I programmed 2 of the three channels to test run. I set the blues to come on 1 hr before and to run with a 8 hr white cycle, and then to run 1 hr after the whites turn off. The 3rd channels for the UV and Reds was left unprogrammed. The UV and reds without a program are in a default on mode. The fans make about as much noise as a large ceiling fan on high. The brightness of this unit compared to my 96 watts of T5 on my fowlr tank is amazing and much more blue in over all spectrum. The unit is setting directly on the glass of my empty 72 bow front and when raised up about 7-10 inches illuminates the entire tank fairly across its 48 inch width.

IMO, the par values are more important than anything. As long as you can estimate where those fall at the different depths of your tank you will be fine. Wait until you get those reds up. I haven't seen colors on my tank like that ever. The magenta/blue strip I bought was well worth the $99 and the dawn/dusk effect it provides an hour after/before my 12ks are on is incredible. I am skeptical about the UV. I would ease that in in an attempt to make sure you don't brown your corals or cause some unsightly algae bloom. This is simply opinion.
