Chinese LED Lights

What color are you going for slayer? That looks very nice!

[Slayer311]

16-18k color temp, and thank you!

[coral_dog]

I purchased 120 led's from China and got them all set up. I love the color and the shimmer is great. I have had no problems with burnout and have had great growth and color from the SPS since. And I did it all for about $350 including the drivers. I sure won't go back.

So from your experience bhazard451 what would be the best full spectrum layout for the d120. Thanks

[NeilCar]

I have been following this and the first thread for a while. I think I am going to pull the trigger on 2 of these.

http://www.aliexpress.com/item/Free-...587062331.html

I am lighting a 4 foot 65 gallon (48x18x16) to grow sps. Is this a good spectrum combination I like 16k to 18k look. I currently have a 100w evolution 14k over a 30 gallon but want to go more blue but not all the way to 20k. I assume this light is similar to all the other leds people have been talking about. Any thoughts or advice is welcome.

Hey guys I'm very new to LED so I want to give them a try.

I have a 40 gallon breeder

36" long. Would one D120 fixture be enough? Should I go with the 90 or 120 beam angle?

There really is no best. Its all down to personal preference.

Just use some violets, reds, and maybe a green or two added in, like in that picture, and the fixture will look great.

Does anyone have a link to a customizable d120 or similar with moonlights? Can't really swing the extra cash for the new ITs.

[cmantis]

You can get the d120 in any layout you want.

Thanks much guys... taking these two comments into account.

I am feeling really good about this layout. Want something warm, that will bring out the coral colors too. Hope she can still change it for me.

If they cant change it, just ask for spare leds. It is very easy to remove the leds and solder in the new ones. It is literally as simple as touching the solder with the iron and pushing/pulling the led a little to remove. You just line up the new led in place and touch the leg/original solder point, make sure the connection is sturdy, and you're done.

I really like the ability to do this, as if you aren't 100% happy with the layout, you can change it until you get the exact look you want. I took the chance on the layout I tried, liked it but knew I could do better, and did something about it

I've been following this thread for some time. Really glad that it's up a running! I'm ordering two D120'S DIY for my reef tank, it's 30" deep. I was wondering if anyone could give me their opinion on my Led color placement. My tank is 90% SPS. I am planning on going with 90' optics. But have been going back and forth on LED placement. I'm trying to avoid a washed out look, but don't want to see to much yellow or violet. Thanks everyone for all the good info. on this thread! This is my first LED light, I wouldn't have known some of the questions to ask without it.

Well Mark yours is fairly similar to what I ordered. I have have used 10000 vs the 14000s in the white's a total 3 less, also 3 more 470 but 5 less 450, and I've added 3 red and 2 green to the mix to help hopefully pump up the colors.

(so in summary I have 3 less whites and 2 less blues subbing the R & G s)

So if you decide to add some reds and greens... take a look at my last (and final) layout just change maybe the 10000K to 14000K if that is what you want.

[bhazard451]

I highly recommend any layout to include reds and violets, as just warm white leds did not perk color up like a separate red led does. Green you don't really need, but that is subjective. I prefer Cyan which looks green visually anyway.

[scubawarm]

Right after my last post, wanted to look into the 450 to 470 difference...

Came across this link. Really cool. IMHO

HEY HAZARD I BOUGHT 2 OF THESE LIGHTS OFF OF AN AMAZON PLACE, THAT WAS BEFORE THIS THREAD WAS EVEN STARTED. BUT MY ? IS AM I ABLE TO CONTACT SAM OR SUNNY AND ORDER SOME DIFFERENT COLOR LED'S OFF OF THEM. AND I AM JUST CURIOUS HOW ARE YOU ABLE TO JUST CHANGE THEM WITH OUT HAVING TO WORRY ABOUT DIFFERENT mah(or whatever it is called) WITH DIFFERENT COLOR LED'S. I HAVE JUST THE BLUE AND WHITE BOXES AND I WANT TO TRY TO GET MORE OF A POP WITH WHAT I HAVE.

THANKS

BHAZARD; what color temp did this turn out to be around?
Im trying for 12K-14K
Thanks

From the link I just posted... it shows the graph rising again at the 520 to 530 area... so I guess adding the greens couldn't hurt. The 490 Cyan is rather close to the 470s anyways.

From scuba diving, it is very easy to see the red disappear underwater. Have used flashlights on a sunny day to see the more true colors of corals. So the bottom argument on the link is valid but pointless. True, these corals normally do not see the color red, even though the chart shows a spike. BUT with red, they sure do look better and maybe they would like it.

SO agree... People put some red in there!

Thanks for the reply's,

I'm going to adjust it to include red and cyan. What leds would you replace with these? and would you use the 660 red? I'm ordering from evergrow, do they have cyan? or close to it? ALso, I'm not sure about the 470nm. I've seen it used in a lot of layouts, what's the opinion on them?
Never having used MH lighting, I don't have first hand expeirence with color temp. But, I think I would like 16k-18k.

Good information, sounds like that if your adding 470, there is enough green in it on it's own and you don't need to add it seperate. So, 470 is more of a blue/green?

I think the ones Evergrow uses are actually 460nm, but you might be able to request 480nm. There is no difference in color to the naked eye to the 460-470 I used next to rb. 490-500 cyan looks green visually.

You would need to know the internals of the box and how it is wired. If it is wired in series, you can replace leds easier. The drivers are very much likely to be under 700mah and will work with bridgelux/epistar leds. If the leds are wired in parallel and use resistors, you wont be able to change them, or it will be more difficult to get it to run correctly.

Color temp is around 12k-14. Add reds.

or

Four of these D120s:
http://www.aliexpress.com/store/prod...587678783.html

All on a 60 x 30 x 24 (l x w x d).

To me, it appears that the SD has a little better spread, more robust and programmable dimming, built-in timers, a remote control (and fewer wires since it is only 2 units). But it appears to be less light overall and if I read correctly, runs the LEDs at 3 watts each (at their capacity) where the D120 only runs the 3W LEDs at 2W each (below their capacity and thus prolonging life). So if money is close to a wash (and it is) does anyone from this or the previous thread have any opinion on which is the better option? Also, for the SD light, there is an option to upgrade to CREEs from BLs for an extra $70 - but you only can use 10K, 460nm, and 453nm. With BLs, you can use 10K, 14K, 18K, 460nm, 453nm, and 420nm. Are CREEs going to put out more light and is the more light worth the fewer spectrum choices? My intuition is that the additional spectrum control would not be worth forgoing for a better LED....

I'm in the same situation as you. Still not sure which LED's to go for. I am at the 36" model which has fewer led's.

They said that the led's are Bridgelux 3W but runs on 2W to prolong lifespan. This is what they sent me in terms of LED combination (see attachment layout #6).

18pcs 14K White
10pcs 460nm Blue
6pcs 453nm Moonlight Blue
2pcs 427nm Purple

I was thinking of replacing 2 moonlight blue to either purple or red.

Does anyone have these lights?

No one has tried these yet. You would be the first.

Keep in mind, the d120 boxes also run at around 2W per led, but they have 55 leds within 16" of fixture. The reason most people haven't picked this one up, is that the smaller boxes are actually stronger and have leds more tightly placed together.

So if would tear one apart and take a pic of it and show you. You would be able to tell me then
