Bought new led light fixture from China.

Hi guys,

First post so go easy on me please. Very new to the marine hobby. Had freshwater for a year and converting my 48x24x24 tank to marine.

Do you think layout as below is ok for sps and lps? I would choose 90 degree optic. I will hang my light above the tank by approximately 5-8 inch. I changed 2 x 12000k to 14000k.or should just have all 6 in the centre as 12000k?

Thanks for your help.

I'm just about to order.

That will work just fine

Thanks for posting this. It's a wealth of information. Maybe someone can answer this for me. If the units are placed side by side, 8-10 inches above the water which is 30" deep, how close do the units need to be to each other? I'm thinking 60 degree optics on everything but the reds which will get 90's or 120's. I think I'm going to go with the Gillguy layout posted in post 81. http://reefcentral.com/forums/showpost.php?p=22113154&postcount=81 just half of it. It seems comfortable to have 6" on each end so the 2' unit should be fine over a 3' tank. Does the same apply to the sides? The units I'm after are the Malibu S150. Do you have to buy the daisy chain connectors separately?

At 30 inches deep 2 units 3-4 inches apart should work. As far as lenses you are right on the edge but I believe also that 60 degree will work and you should get full coverage. You don't have to buy the daisy chain it comes with package. I got one and it with not needed. Just make sure you ask.

I mean the tank is 30" tall. Footprint is 8' x 3'. Each unit is 8" x 24". If a 2' unit is good for a 3' tank, then we can say that the light will safely extend 6" past the fixture. You have a 4' fixture over a 5' tank with good coverage, 8" unit covering the 18" dimension, same concept. So using those same parameters, would I space the units 12" apart, following the theory that each light will project 6" beyond the units edge? So the tank layout would be... 4" space, light, 12" space, light, 12" space, light, 12" space, light, 12" space, light, 4" space. Does this all sound reasonable?

Ok I understand now. Here is the deal with your set up. You definitely want 60 degree because of the 30 inch tall tank. It will work if you can get the fixture at a height of 12 inches and probably might need 14 inches. If you can only get it up 8-10 inches you will probably have problems in between units where the 12 inch separation is at. The reason it might not work for you in the setup you described is because the 12 inch separation occurs in the middle of the tank. It works for me and others that have purchased a unit one foot shorter than the tank with 60 degree optics because ours have only 6 inches on the sides and we have them 12 inches or higher of the water line. Others that have the units lower used 90 degree. You with 60 degree optics in the center could possibly not give you coverage due to the angle of the light from that height. For example, If I lowered mine to 8 inches, the very top corners of the tank will not get coverage. That will happen on yours at the center. To get full coverage I would need 90 degree. Unfortunately if you absolutely can't go higher then your best option will be to get two 4 foot units and two 3 foot units. This will give you 7 feet across. you could separate the units by 4 inches side to side and then you'll only have 4 inches on each side of the tank. That will guaranty full coverage with 60 degree optics especially at the center of the tank. But I know that's more money. It's a big investment but you want to get it right and not regret it.

I can definitely go higher. As high as I need to go. If I do go that route, I think I'll pick up a par meter so I can raise it to the ideal height so as not to have any poorly covered areas. It would probably be wise to pick up a couple extra units in case I need more. If not, I'll use them over the frag tank. :spin1:

anyone else that's ordered get an email saying there will be further delays due to some controller board issue? the factory sent the wrong sizes.. so will be a delay in shipping?

yes mine is delayed but will be shipped next monday

 

[Silfer]

Hmm, hope mine too..

Customer service is excellent other than the fact I was told when I placed my order that they had everything in stock and it would be sent out last week.

 

[zab34]

Got the same email as well. Real bummer. I was also told they had almost zero lead time and they would ship soon after ordering.

 

[conix67]

I ordered a black fixture and was told there would be delays up front, so I wasn't too concerned about this. I can wait few days and take some time to figure out detailed plans on lighting system switch over.

 

[jimnchal]

Anyone else have an issue with being shocked by the light. I was putting in my new wp-40s and my arm touched the bracket (canopy is being built) so I am using the metal brackets sitting right on the tank. And felt a shock. I am going to put a volt meter on it to see how much current I am getting.

I was told everything was good with the light fixture, also in black, but the controller was delayed a couple days. Our order would ship complete on 3/17 via FedEx and would arrive around 3/24.

Hey Gillguy, you seem to be the expert on LED Zeal
my tank 36x18x12.5 rimless. I plan to get the one s150, should i get the 90 or 120 lens? will the 90 be too intense for a shallow tank? Are you still recommending LED Zeal?

Well it's 3/17 and no email with tracking details and I ordered near 2 weeks ago.

I ordered about the same time and I received an email today that it has been shipped out. Have not received a tracking number.

Do you guys have a specific plans on acclimation? Is there a simple rule I can apply to adjust light intensity of LED fixture coming from a T5 setup - 50W of T5HO = 30W of LED, etc?

Get the 90 they will work fine with your tank

Start at 45% on the blue channels and 40% on white. Increase 5% every week till you get to around 70%. Depending on what corals you keep you could go higher. I had to stop at 70% then increased slower by 2% a week. I'm now at 80% on blues and 70% white channel. Also if your t5 fits with the unit keep them on for the transition. A you increase leds decrease the time t5 are on.

I looked at the LEDZeal webpage and the store is down, claims maintenance in a popup when accessing the link from the bottom of the page. Is this a normal occurrence?
