Chinese LED Lights

My tank is a standard 75G, 48" X 18" X 21" deep. I'm considering the IT2040. If I have to mount them only 4" above my water (I have a canopy) will 2 still cover the entire 48"?

Should I get 90 degree or 120 degree optics? Can I get the 90 degree optics separate in case my situation changes?

As far as changing the LED'S is it pretty easy to get them in correctly or does it take a lot of precision because they need to be soldered in a very precise position?

So I guess the real question is this for those of you who are using black boxes, which ones would you most highly recommend for a 75G SPS light reef and how many? Obviously it seems to be all about spectrum, but do you feel these lights are currently at a point to provide long term sustainability with the proper wavelengths being included? If I was to order a base model (D-120) with spare LEDs to get the proper grid, how hard is the swapping of LEDs and what equiptment would I need on hand to complete such tasks? Thanks for your time and any info you can share.

The lights can grow SPS. I have one as a reference over the past few months that is growing. Looking to add more in the near future.

The leds are very easy to swap. All you need is a soldering iron, and maybe tweezers/pliers. All you do is line up the new led legs on the solder points and touch the soldering iron to it, and the board "sucks it in" so to speak.

Two IT2040 will work great over a 75. The optics they come with are twist on, so they can easily be removed if you want to for more spread in the canopy.

Thanks bhazard
 
bhazard451, you wrote, "The optics are nice. They are twist off, and easily removeable/replaceable."





are all of the evergrow lights with optics screw off?
 
Will these units reach 30" deep tanks?
I have a 48 X 24 X 30 deep mixed reef. I have 1W 120 LEDs on it now but want to move up to the 3W units.
Thinking about 2 of the IT2040 or 2 of the Evergrow units.

What do you think?

I would think if you were happy with the 1 watt units. Double the output would definitely help:-)

What are you trying to grow in the sand bed?
 
Ive been working on my build for a long time with many set backs. After a year Im finally plumbing the tank to the basement, and should be ready to fill it...hopefully in a couple weeks. One of my biggest concerns with my build is the ELECTRIC BILL. This is way Im thinking about switching to LED's. The inital cost is a concern too. This is why Im going to replace my 3x250w & 4x54w T5's. Ive done some research and I've read this thread, but it's still very confusing with all the different options. My tank is 84"x24"x27", and I have a canopy. Im planning on keeping a good amount of SPS corals so lighting is important. Like many others I want my coral to "POP"(went to my first frag swap & was amazed at the colors), but also want to find that fine line where I will get good growth. I cant afford the $500-$750 fixtures out there because of the space in needs to cover. I was looking at an ebay full spectum fixture, but after reading this thread I'm thinking they are getting them from china. I am also planning on picking up 5 fixtures. I really like the Hamilton 14k bulbs, which are white with that hint of blue.
If anyone has any recommendations that would be extremely helpful. If you want to PM me advice thats fine too. Thanks
 
From the previous thread:

If I wanted to mimic the below the picture, would I use more ww? I really like this setting because it looks like natural sunlight, but colors are not popping in this tank.

If you want a nice sunlight mixture like that, try to mimic the layout I used. Add in 2 or 3 reds as well, and you will get a really nice high noon 12-14k look at 100% with popping color

What would you remove to put reds in place of?
 
Ill try to find previous thread. Im still wondering if there is a basic set up people use and substitute reds and cyans but not sure which one. Again im a complete novice and this is my first attempt at a reef long term.

Replace some whites with reds/greens
 
Ok. According to the info these units should cover what area? I have a deep tank. 31 inches deep. 31 wide and 90 plus long. Thinking of using units in perpendicular arrangements. Thoughts.

Thanks, bhazard. Would you think that even 3W CREE LEDs would not be able to match two 250w halides? The question for me isn't necessarily about matching the current 400W x 2 that I currently have (as it is probably a little overkill) but whether or not that fixture - with BL or CREE LEDs would provide enough light in the middle 4 feet of tank.

So here is the final quote I got:


48" x 10" x 2.5" fixture - 88 x 3w Bridgelux
88_3.png


Color Temp #
White 10K 14
Cool White 14K 16
Blue White 18K 8
Moon Blue 453 14
Royal Blue 460 28
Actinic Purple 427 8
Total Leds 88

Around $550, shipped. So two issue I am on the fence on:

1) Is one of these enough for a 60" x 30" 24"? or do I need two? I am getting differing opinions on whether or not the hanging height that will give me enough spread will give me enough intensity

2) There is a built-in auto dim timer function that I think I would rather not have. I believe it will be a pain to program to work in conjunction with the rest of the controller I have (Apex or ACIII). The only downside is that I will also lose the remote control that allows the blue and white channels to be adjusted - instead it will be manual potentiometers. I do not believe it can ramp the colors up or down throughout the day (even with the built in timers) and it saves $50 off the cost. I am not sure I care about anything other than being able to tweak the color, but changing colors seems to be something you tweak as the light is first set up, and then forgotten about. Do any of you with LEDs that brighten throughout the day find it to be a big feature? Coming from the world of MH, it seems to be but a bells and whistle thing.....

These are the operating instructions, you will probably need to view the attachment to read it:

What do you all think?

For only $50 off, you're better off keeping the dimming and remote. One should be enough.

If you do get it, let us know how it is.

I wonder if one will be enough for such a wide tank. Sure it will light it up
But will it have enough par.

Skyne, what do you plan on having in the tank?
