Chinese LED Lights

[Ron Reefman]

Did you order yet?Which lay out did you take now for the IT 2080?

We are doing a group buy of 15 fixtures, 7ea D120's, 7ea IT2080's and 1ea IT2040. My layouts are shown in the last page or 2 (the one bhazard451 wouldn't comment on... LOL (just teasing bhaz). I expect to place the order on Saturday when I get the last layout and money from one buyer in the group. With 7 people involved in this buy, there were a lot of questions and Helen at Evergrow has been very prompt and considerate. They also gave us some pretty good prices! WooHoo!

Do royal blue and blue and violet in general give off more par correct? Then if i am looking for a 20k look i would get more growth it seems like? Please correct me if im wrong

Been lurking around this thread for some time, reading and learning. I have a 120 gal. 48" tank with a large amount of rock work that extends within 3" to 6" of the sides. I need good light coverage to keep each tank end out of a light shadow.

I am currently leaning towards Reef Breeders but I am thinking the 32" light would not give me an even spread at each tank end- 8" gap.

In the discussion of lenses, I have never seen any comment of using different lenses in different areas of the light. EX. 90 degree in the center and 120 degree on the ends. Anybody have experience using different spreads on the same light?

My tank has a plastic center brace. I am thinking this will cause a light shadow using a light field like the Reef Breeder design.

Guess I will have to go with two of the 120 boxes.

Damn so should I try to get 120 degree? I thought the 90's would be good enough on a 48" tank

It depends on how high you can hang the lights. I have a canopy, so I'm limited. At 8-10" above the water line, you will not get the coverage you need with 90 degree optics. If you can hang the lights, you may have a different result. I have 24" front to back to cover as well, so not sure what you are trying to cover. They recommended 120 degree, but I too thought that 90 degree optics would be better. Oops...

I have thought about that too. Can we put two different lenses within the same fixture?

I have been reason old thread and now parts of this this is kinda what I'm thinking about ordering I have a 150g bow front ill be using 3 of these over it. It's 6ft long 24 wide in middle and 18 wide at ends 24 deep I believe lmk thanks

That's my plan. I'll let Evergrow put 90 degree lenses on everything and when I get the light I'll remove the lenses from the UV, violet, red and green leds to get a better spread of those few leds and keep the 90 degree lenses on all the blue and white leds.

sounds like a fun idea and experiment. especially if you can position the LEDs on your layout appropriately then you can maximize their location despite the limited number of them, hopefully. the lenses are super easy to swap too and cheap and soon available from reefbreeders too with LEDs so no reason not to play around with it.

I'm even considering taking the lenses off the back 2 rows since my tank is a big rock wall that starts about 8" off the front glass and goes almost to the water surface at the back glass. No need for 90 degree lenses back there. The rocks will only be 12-18" from the light. I just can't wait to get this order in to EG. We had 15 fixtures in a group buy and have been working on it for a couple of weeks. This morning 2 more guys called me to add 5 more D120's to the order! Now we are at 20 lights. I wonder if 5 more will get me anything in cost reduction? I'm not holding my breath, they have been pretty fair on prices already.

As I understand it, and I claim no expertise, blue light does NOT give higher PAR. It's that Apogee PAR meter's sensor (by far the most common one in use) that reads blue PAR about 10% below the real PAR. So if you just have on blue leds and get a PAR at the sand of 250, it's really more like 275.

And blue light penitrates the water better than other colors. The zooanthellia in your corals use blue 420nm-460nm and red 640nm-660nm and white. They all feed the photosynthesis process in the zooanthellia. What the coral polyps themselves want... we don't really know.

But don't take my word for it. Anybody agree or disagree? :reading:

 

[latinyoungn]

i read a few pages back, (i think page 7) that 120 degree optics is like having no optics at all. can anyone verify that? I ordered 90 degree optics but this is going on a 1 foot canopy and im thinking i should change it asap. unless i can just take them off to be like having 120 degree optics

and bhazard, good call on the new ReefBreeders layout, i am going to check it out

 

[mrbigshot]

I planned on taking my optics off the colors like you and some that are directly over the rock. even with a sps only tank I dont need 800 par up high unless I'm doing some select acros. most will tolerate it but I can't tollerate the spotlighting.

[bhazard451]

It's extremely easy to remove the optics from the IT2040, so just get 90 degree optics anyway. Removing the optics would give you around a 120 degree beam, so 120 degree optics are somewhat pointless.

You can try removing the optics on colors only, but I didn't like it when I did it. It reflects off of the other optics and looks "off" to me.

 

[cmantis]

Unless Evergrow changed it I think their led's are 90 standard not 120.

 

[Travis1787]

If you take off the optics though I think it void the warranty cause to do so you have to undo the screws which has the "if you remove this sticker your warranty will be voided" ... I may be wrong but I would think that Is the catch....

I ready alot of your posts etc. I remember in last forum you said do all royal blue also was wondering on the d120 when you say 33 blue 18 white 4 violet what Nm blues and what kelvin whites.

10 20k white
9 14k white
20 450nm royal blue
12 470nm blue
4 420 nm violet

How's this sound?
Or should I do a different kelvin white

[Travis1787]

It really depends On what look your going for color wise I like a 20k look and I'd go

32 blues(450)
15 whites (12k)
4 violets 2 red 2 green .... this should be close to a 20k look with a tad over 2 blue to 1 white ratio but I'd rather use more of a mix of whites like maybe

35 blues ( 25 450 and 10 470)
12 blues ( 6 65k, 4 12k, 2 warm white)
Then the rest red violets and greens ...

If you like your tanks more white then 20k then have to make it more of a 1.5 or 1 blue to 1 white ratio ... bhaz would be better to tell you how to do a 14k-16k look cause that's more his taste

 

[reefman300]

I am a more blue person. I just am not to sure the equivalent in the led to make 14 16 20k lol. I put that together in a couple days of reading post and looking at other pics and listing people put. I think me and a friend are gonna order 3 each.

Currently I have a maxspect led i bought from a guy who DIY it into Cree 3w LEDs the cree xre I believe it's 56 LEDs and it has 38 blue and royal blue unsure exact amount and 18 white he thinks there 6000k white but that's a good look to me but not sure what to do yet. Thanks for any help

 

[reefman300]

Idk why it will only let me add one attachment from my phone this is a zoa under the led 38blue 18 white maxspect with Cree xre LEDs all on there is no dimming but still very nice light.

With the reds all in a row will that make a spotlight across the middle? I had the pfo solaris greens to me did nothing really.
