Horrible ratio. It would look like an 8-10k light.

2blue:1white for a 14k look. 3blue:1white for a 20k look, then add a few violets.

Moonlights are a nice touch. I added a string to the outside of my light because I missed them. Either light and company could do any spectrum you wanted them to.

I totally agreed w/ you that was a horrible ratio.

Sure the Vertex are nice, modular, with controller, but you're right.. you gotta pay ferrari prices for it. Just adding red/green/uv to the Vertex bring the price up to Radion prices.

These fixtures are like getting a ZR1 corvette. Doesn't have the same flash and extras, but the performance is there for half the price or less.

bhazard, is the d120 running at 100%? have you tried lowering the d120 to reduce the spread? what are the dimensions of the tank? how many inches from water line is the a4 at? do you have a link to the reef breeders light? sorry for all the questions. the pic with the a4 looks considerably brighter.

D120 is running at 100%. It is definitely dimmer than my Nova, but my Nova has more powerful drivers than standard. Whites show up better on camera than blues. The d120 is definitely bright. My whole room is practically lit up. The Nova upgraded is now running closer to a full 3W instead of 2W, and with optics, so it is considerably brighter.

I'm lowering it slowly to reduce the chance of burning coral.

A4 is 10". D120 will be coming down to 4-6" so I don't blind myself.

The reefbreeders light is just a d120 with red,green, blue, and violet bought in bulk to sell. I did notice the red and oranges in my clownfish pop more, so I think having a small amount of red, green, cyan, and violet does look better. This can probably be ordered cheaper from the chinese companies direct.

bhazard,
what optics are on the Nova? thats a pretty big difference?

90 degree optics. They can be added to the d120 too for a little more. The d120 covers a much wider area without optics. With optics it would increase in brightness but lose its spread.

For a tank like Travis' (39" length?), not having optics works better for him, as he can have 1 d120 cover the whole tank. For a 24" nano like mine, lots of light is wasted and spills out without optics.
 
oh..ok.
I understand what you are saying. I didn't know your tank was 24" .

I'm working with a 40 breeder 36" wide. The link you provided for the ( in bulk D120 with reds & greens ) looks like what I was looking for. Is this the same company you ordered yours from> if so , how long did it take to recieve it?

Thanks for all your input & pic posting

if i go with 2 A4's what do you think of this mix;

dimmer 1 =

8 cool white
8 warm white
4 royal blue
4 blue

dimmer 2 =

10 royal blue
10 blue
1 warm white
3 violet

your thoughts?

I haven't seen how warm whites blend yet, so I don't know for sure. Maybe 4 violet 420nm instead of 1 ww on dimmer 2? Could look really good. WW and Violet would help bring out reds, oranges, and a bit more coloring. WW is very yellow, so having the same CW or more is a good idea.
 
I have a Chinese 60 watt Cree fixture. The first thing I did when I got it was take it apart and inspect it to see if they are real Cree LEDs. The look the part but they are not on star boards so it is hard to actually tell. Either way the fixture is working really well for all of my SPS. At first it was too much so I had to reduce my photoperiod and slowly amp up the lights. I also removed the glass on mine. The fixture is about 18" above the water and the water is 12" deep. Most of my SPS frags are about half-way up. I would recommend this fixture to anybody keeping any kind of coral.

Reefbreeders just buys them from alibaba.com like we are doing. They are in the US and I ordered from them. Originally they said they could do Apex dimming with the drivers it came with, which I questioned, and it turns out they can't. That was why I originally ordered it.

I'm using it as a temp light while testing a different pair of drivers on the Nova, and then eventually upgrading it to Cree leds. I might sell it off at some point, or keep it for my 120 gallon cichlid tank that will eventually be FOWLR.

This is basically the same thing for less money. This one even has moonlights. The Chinese companies ship via DHL overnight and it comes within 3 days.

They're real. You can try to look at a Cree XPG or XPE spec sheet and see if the led emitters look the same.

All of these 3w fixtures work really well so far as an alternative to Halides and T5s, and as an alternative to the fancier, more expensive fixtures on the market.
 
Wow ,
thank you very much for posting that last link. I was just saying ..this light would be sweet if it had moonlight seperate. I will be ordering these in the morning.

very helpful. thanks again
 
I'm having some, and I believe it's the language barrier, problems with Hendy and my d120. I ordered one with 24 blue 4 uv 27 white. I got 28 blue/27 white. I've tried to explain this but he's just not getting it. He even sent a copy of the order which state the 4 violet leds and I paid 180 something for it. I hope I can get this worked out. It did get here awful fast.

I know the guy linked at the bottom of the page at Prestige Reefs. He is a good guy who live near me. Those Pharos are really nice and have all the goodies that the Radions have. They are bit pricier than the Novas and D120s though. Still, well below the Echotechs. He just started selling these (after I had purchased lights). Any warranty is taken care of by him.
 
I've seen at least 2 or 3 people whose order got messed up in dealing with hendy... Id say deal with sam only no offense to hendy.

My tank is 36" close enough bhazard lol and mine it in a canopy and the inside of my canopy is white so any spillage is kept in the canopy and if anything reflected back in the tank...
