They are for bringing out the pink orange and red colors better I think its just preference I don't think its a must to have them but I don't think it hurts to have them either.

I can't tell ya what ratio to go with cause I don't know your liking I can tell you idont care for any of there ratio too much on aliexpress the only one I've seen that's even decent is the 30 blues 25whites and I don't even really like the sound of that for my liking. I think any of these ratios would look good

34blues 17 whites 4 violets
33blues 18 whites 4 violets
31 blues 20 white 4 violets

You can always do just 2 violets and add one more white and one more blue to any of these ratios

Thanks Travis. I'm going to stick with your original recommendation of 34 B, 17 W, 4 V combo.

travis - sent ya a pm, it was regarding the email from sam and your thoughts on the 90 degrees led or the 120 degrees led. i saw he noted they'd be using 90 degrees led, not optic lens...

[Chicago]

what about these?

[Chicago]

has sam considered using the new crees? i would assume one of the chinese manufacutreresis is.. no... yes?

[ReefTrigger]

I just ordered these off Amazon:

http://www.amazon.com/gp/product/B00...ls_o00_s00_i00

they are the 3W Led's, and the blue and white are each individually dimmable, with a 2 year warranty 120 watts ... $180 shipped

I thought I'd give these a try, anyone used these before ? I'll post a review once I get them if anyone's interested ..

[Mr Neon]

Sam emailed me also about the D120 and said 90 degree optics was much better for the tank..Kinda confused now...Told him leave it at 120..

[Dobbs1101]

I just ordered the D 120w with 30 blue and 25 white for my 30g LPS tank. If all goes well I'll purchase 2 more for my 120g SPS tank.

I was thinking of getting 2 - A6 for the 120g. Do you think that is too much for a 4x2x2 tank? My thought was that I can always turn the lights down. Or do you think the A4 or D 120w would be fine?

Also, when I purchased I just used the Buy Now button and filled out the form. I sent an email too but got no response. I did however get an email that said Payment successfully made with an order number. Do you think everything is fine, or do I really need to contact Sam?

[Travis1787]

nIf you got the standard ratio should be no need to email sam you should be set

As for your 120tank its all your preference... If your tank wasn't 24 wide id say 2 d120 would be pleanty but not sure how well it would cover 24" of width I know it covers my 18" wide tank good. Worst case you could get 3 d120s and run them front to back instead of longways left to right... Put one every 16 inches and you would be set and it would prob me cheaper then 2 a6

[Travis1787]

According to sam the 90 degree lenses are very similar spread wise to the 120 degrees but the 90 penatrate better(which would be better for coral growth and keeping clams in the sand happy) so to same the 90s are better.

I trust sams word so don't be scared to go with 90s I don't think uoull be disappointed

Hey all,
I just placed an order for these:

http://www.alibaba.com/product-gs/54...ium_light.html

I got the cool whites changed to neutral whites with a leg kit and shipping was $227. I liked the three dimmable switches and they were more than willing to customize colors. I havent received it yet (Just ordered on Friday and they had to customize with the neutrals) but am excited and will let you all know what it looks like.

This is for a BC29 if it matters.

I really like that one. Moon lights + leg kit is nice.

Here's my A6 on my 39" tank


Sorry for the poor pic quality, really hard to get a good picture with LEDs on an iPad. Corals are a mad from alk swing from bad batch of salt.

Will post more pics later with different intensity of blues and whites.

[bhazard451]

Looks great!

It also looks like two A6's could eventually cover my 120 gallon 72" tank, based on the spread you are getting over your 39"

I have a question. I bought an LED fixture off of ebay before I found this thread. I saw that it had a heatsink and that the LEDs were 3w being ran at 2w. The fixture looks almost identical to the Nova A4. Same 4 circular clusters just different air exhaust ducts and its not dimmable. The problem is that it is insanely powerful. I bought it Thinking it would be just a pretty good light and it has exceeded my expectations. I have it 21" above the tank and I still get 200 - 350 par at the sand bed. The tank is an 18" cube and I keep mainly zoanthids and they are pretty ticked right now. I have cut the white lights down to 3hrs and will add an hr every other week. I would like to put a couple dimmable ballasts in there but I have no idea how, or which ones to get. I do not really care about controlling with the reef keeper that I have just want to be able to tone it down a little. Does anyone have any suggestions? These are the lights I got

Feature:
1. Newest cooling system, revolutionary heat dissipation design, greatly alleviate the internal thermal cycle, 10-15 Celsius lower than its precursor in performance.

None of them are yet. The first one will be the Maxspect Razor coming out in July. That one will be around $480.

[rich850]

i am wondering how others have suspended eshine fixtures and if you have any pictures?

I did a write up in this thread on a wall bracket I made. Others are putting it on rails in their canopies, some from the ceiling, etc.

I'm in the middle of a driver replacement right now. It won't be simple.

You'll need to open the lights and see what kind of led drivers they are using. If they are not labeled with voltage and current, don't even bother swapping them. It is similar to my A4 unit, but may be wired differently and use different drivers.

You will need to closely match the voltage of the drivers on your replacement ones. The current will need to be similar too. It would have to be a dimming driver, and you would need to solder a potentiometer onto each one. Then, on top of that, you'll need to rewire the fans onto their own outlet, because they use some kind of voltage regulator pcb that I haven't figured out yet to power the fans through the drivers.

You're better off just selling the light if you can and re-ordering a dimmable one. Its so much easier, and it would cost nearly $100 in parts to do it yourself.

[cec09]

gotcha. Thanks. Maybe Ill open it up and take a picture

[tankaddict]

Anyone get charged a 9.40 dollars for transaction fee for buying their light?

[Travis1787]

Nope sounds like something to do with maybe your card company though

[ihigh]

Sam said he'll mkae me a custom link, but it'll take some time. hoping I can order tonight! most of my fish and inverts are coming in tomorrow...=(

[bhazard451]

Unless you're very good at re-wiring things, I don't recommend doing the driver swap to 0-10v dimmable drivers.

I got everything wired in, but its a complete mess inside. I'm still not done, and this is with 3 hours of work into it. I also stripped one of the ac wires, so I have to rewire that, which is gonna take even more time. I also chose to solder wires after using wire nuts, as the wire nuts weren't holding that great. What a mess. The amount of work just wasn't worth it for me.

I ordered a reef builders? fixture, but I'll have to wait 2 weeks for it. Going to see which fixture I like better, and then move one to my 120 gallon.

I'm hoping the Evergrow guys release a true 0-10v Apex dimmable fixture soon.

I like the ratio you wanted so could you please post your custom link here when you get it? Thanks.
