chinese led lights

[OrrG]

I was following this thread religiously every day for a while but haven't kept up lately, going to keep my halides and T5s for another year at least, so I'm not sure if this has been covered or not.

What would be the best layout on a D120 for a refugium/macro algae planted tank? I'm upgrading my fuge to a 40 breeder and wanted to try out some of the different macro aglae. I'm thinking lots of 3500k and 6500k and some reds. Was going to go with a 36" T5 and some GE 6500k bulbs but figure this could be a better option.

Has anyone done a layout specifically for a refugium yet?

Evergrow sells grow lights for plants too. I'm not sure if it would work for macro algae however, haven't looked into them.

The new fixture is now shipping. I'll post pics and impressions as soon as I get it. I'll post a full review once I let it run for a day or two.

I cant find any places to borrow a PAR meter from, so I'm going to buy my own to test these with too. I'll be able to take measurements soon enough.

I'll also compare it to my Cree/Luxeon DIY. Its too bad I dismantled my Twilight fixture for parts, or I would have compared them.

Anyone try the new lower color temp leds mixed in yet? Any thoughts yet or people still sticking with 6500k and 15000k leds?

Any ideas on price yet from them?

Most of LED grow lights are for growing Medical Plants/Tomatos/Vegetable, less people use for algae, you might be the first one.

Keep in mind it is a pre-production sample. There could be a change or two in the final shipped unit when they are available.

The labor day 10% sales luckily have coincided with my need to purchase a PAR meter.

This is the default custom sunrise/sunset setting. If you can think of a better one, say so and they will use it.

Any ideas about price yet?

I have a Taotronics (Chinese) 140w LED fixture over my 60 gallon cube. Supposedly this fixture was designed with ease of maintenance and customization in mind and it is supposed to be very easy to replace LEDs in the fixture.

I am considering making some changes and converting it to a more full-spectrum-like fixture. I would like some input/feedback from those of you who have built or customized full spectrum fixtures. This is what I have in mind... The layout may not be exactly like this, but pretty close.

They're still working it out. Since Reef Central members have bought quite a few fixtures from them, they're going to offer a promotional discount for Reef Central members for the first round of lights, which is very cool of them.

If they can do it, it will be a competitive price. I'm hoping for $250-$300.. but if they can get it lower that would rock too.

You have to know how they are wired and what drivers they use. If the driver is around 90volts, then 24 leds are wired in series each driver. You can replace the leds if thats the case.

If the drivers are 48v or so, they are wired in parallel, and you might not be able to swap colors because the forward voltage of the different color leds are different.

If you really want to go nuts, you can gut the whole fixture and replace the whole thing with Crees, Luxeons, and SemiLeds like I did.

There are two drivers, one for whites and one for blues with 24 LEDs on each, currently the fixture is 1:1 white/blue. The drivers are each labeled as you see below...



I just disassembled the face of the fixture to see how easy it would be. Several screws and a few lenses later...



Very easy to disassemble/reassemble and the leads are very accessible for soldering.

[bhazard451]

The problem is, those are running in parallel. You can't mix colors or different LEDs, because they have different forward voltages. There are also resistors/fuses being used most likely to prevent the entire string from blowing up if a led died.

"Because the LEDs are in parallel, the diode with the lowest resistance will be lit the brightest, while the other diodes will either be dimly lit or not lit at all. For this reason it is imperative that any LEDs you plan to wire in parallel have as close to equal resistances as possible. A good way to ensure this is to buy LEDs with identical model numbers and colors."

The Novas and d120s are nice in that they use high voltage drivers in series, which basically allows you to swap any led color. High voltage drivers are more dangerous however, so take safety precautions.

Bhazard, your killing me. Now I cant wait for you to get those lights. You shouldn't have told us they were shipped. Now the suspense is killing me. And I know I have to wait another week now. Lol.

You wont have to wait long. They ship incredibly quick... less than 3 days. I'll have it up and running the same day I get it, and I'll take PAR measurements when I get that too. Keep in mind I have a custom ratio, and all custom ratios will measure differently. Pricing will be key.

Just saw this. A PAR38 bulb made for growing algae.

As promised I took a photo of the growth im getting with these lights (D120) close to 3 months.

Unfortunately my camera skills are lacking.

This photo is from November of last year. so not all of this growth is the new lights, but most of it is.



I've circled the two coral that weren't growing under my old tired halides\T5 combo.



I know the white balance is way off on this second photo. like i said my photo skills are lacking.
Unfortunately this is the only photo i have to use for comparison.

Also i just finished installing more royal blues.
My fixture is now:
D120
55 total
46 RB
9 CW
I really like the look

Awesome! 46RB and 9CW? 5:1? Wow you must really like the 20-22k look.

[Zedar]

LOL yeah I do like it blue

My reason for posting the pics was to show the growth with mostly RB if anyone was wondering.

Those picks look wayyy more blue then in person.

[bhazard451]

They look very promising. If they can hit near $250 shipped, that would be pretty awesome for a light with a sunrise/sunset controller, with lcd, with wireless remote control, with optics, with moonlights, with an aluminum heatsink, and DIY layout capable. It would be nearly half the price of an AI fixture (minus the crazy colors, thunderstorms and software), and $150 under the Maxspect Razor 120w.

[denny crain]

Mine d120 shipped last night. I ordered
Dimmer 1: 24 Royal Blue, 4 violet
Dimmer two: 2 royal blues, 3 blue(460), 3 cool white, 11 netrual white, 2 warm white, 2 green , 4 red
Ill see how it looks.
Ill post pics when I get it.
