New thread: LED info only for ATS's only....

[MidwesternTexan]

Here are the specs for the lights I posted about above:

Specifications:
Voltage: 220V
Power: 30W
Light angle: 120°
Material：Aluminum
Waterproof level: IP65
Led chips: 10 series 3 parallel
Leds: 24 pieces red chip：620--660nm + 6pieces blue chip：450--470nm;
Service life: 50,000 hours

Also, sort of a typo, b/c 85V-220V will push the drvers just fine.
I wired a 3 prong plug per the directions that came with it.
The is also a sticker on the light that has a check marked box beside 120V.

Others using the smae light state they're getting great growth.
They take up WAY LESS room than the CFL in those big dome reflectors too.
I'm liking them already. The Red light is cool too

I read the complete thread. No offense to Floyd, but his name does not equate to scientific peer reviewed papers. In a macro algae refugium, I used a hydroponic fixture with 1:1 ratio of red to blue. I was very happy with it. Does that make it better than a 3:1 ratio of red to blue? Not necessarily, but it was my experience.

I don't use an ATS. For me, the discussion is academic.

Subsea,

It's nothing personal, I'm SURE you are a great person, intelligent, etc.

BUT- you just stated you don't use ATS's.- Thats fine, up until about 6 months ago, I didn't either.
And BUT- the title of the thread, specifically LED info for ATS ONLY!

I should know- I'm the OP!

Every topic has data, research, etc.

Please, this thread is about LED info- FOR ATS's
Just yesterday I put one of my 2 screens on LED's, and doing my own comparison My LED's, vs 2700K CFLs.

In the last 10 days my screen above is turning the lighter green like the small patches on the right.

Its filling in the bares post as well

Here is one month growth from the 30w light I posted

To large a screen for 1 cube a day, but growth is even and coloring up.

Does that have saran wrap covering the shole sheet, keeping all the water in and the splashing down?
Also- lighting one side?

Looks like excellent growth

 

[outy]

No saran wrap

And yes just lighting one side.



I feed 1 cube a day and that screen is way to large for what I feed. I really need to cut it down which would increase growth rate. But I'm just going to clean it every two months and see how that plays out.

 

[MidwesternTexan]

Thanks for the reply outy,

clean it every two months? If you can wait that long- good luck on that one.

I feel that my 2 sheets, each slightly over 10"x10", light both sides is more than I need.
Definitely slightly more than 400 sq. in. lit.

Hopefully, my experiemnt will indeed show that these LED outgrow the CFL's-

It should. That's where my money would be bet.


I have a 30w identical light in 6500k, I could place on the other side and experiment.

Here is 6 weeks

Here is 6 weeks

Hi outy...just wondering if you could give me the approximate length and width dimensions on that LED fixture. The seller on ebay is not much help. Also, I may have missed where you said it but how long are you running these LEDs every day?

8.9 * 7.3 * 1.9in


18 hours a day.

12 hours for first 3 weeks

What's the most ideal ratio of Red/White/Blue LEDS?

and floyds response

Skip the WW and go all red. If anything mix 50/50 660nm and 630nm and maybe 1 455 or 425 blue per 6-8 reds, if any blues at all. Nothing is 'proven' yet but there have been a few getting good growth with only 660 and only 630 so mix 'em and that way you're covered.

That's a really old post (2011). There has been a huge amount of experimentation since then. I think you'll find more up to date information on the more recent algae scrubber basic and advanced threads here, or look at Turbo's Aquatics site and see what ratios they use on their current scrubbers.

In general, people seem to do better when they match the spectrum of chlorophyll A, which is stronger in algae, rather than B (i.e. 420nm and 660nm), and I think that is what the latest Turbo's Aquatics scrubbers use.

I have red these sites well.


Your welcome to quote and source anyone who shows an increase in growth over red alone.

I know Floyd has recommended all red and Paul used all red, and I thought Floyd has mentioned a sort of bald spot where his blue led was.


With that said I do run a few blue myself mixed with a majority of red.

 

[MidwesternTexan]

The ones I posted the specs for are mostly red, some blue.

After Day 7 of my CFL vs LED experiement:

They both grew about the same amount,
yet the LED's side is much darker, while the CFL side is a brighter green?

I have 3 x 100W equiv. CFL's on the one screen, 1 on one sice, 2 on the other (fit my space better)

The LED's are 2 x 30W (advertised W)- one on each side.

Didn't SM state that he thought the darker meant pulling more nutrients?

Not sure but if he did it would mean for a run in well established ATS

I run my ATS in a 5gal bucket. I currently use these... http://www.ebay.com/itm/371480172206?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT

This pic was taken on day1



The lights are working and growing algae now that I'm close to day 40, but I've decided to try these... http://www.ebay.com/itm/29167094014...49&var=590701284790&ssPageName=STRK:MEBIDX:IT

I think I'm gonna "line" or "wrap" it around the inside of the bucket, so in a sense it'll be 360* lighting instead of two spot lights. Who knows but I'm gonna try it. The new lights are supposed to be here today.

Those are the 10 Watt units? How big is your screen? I would think that the white bucket can only help with reflecting all the light back onto the screen, has the growth been good once it started? I am looking at the 30 Watt models for a scrubber I made that is 7" x 7" but it's not going to rely on any reflected light like yours. I can't decided if the 20 Watt units will be good enough though.

Yes, I use two 10watt 12v units with a 12v 3a power supply and they are mounted almost at the top of the screen about 4.25" away and point downward to help keep stray light in(see pics).

First 3-4wks it was on a 12/12 light schedule, then moved to 18/6.

My screen is 9"W x 10"L, which is big I know for how I feed.

Because of the larger screen and since I don't feed per the "cube rule", mine took a few extra weeks to get going. But now it grows just fine, I clean/scrape one half of the screen every seven days, and alternate sides like recommended.


Day 1 with CFL until LEDs came in...




Week 2 with 10watt fixtures...




Today(3/20/16) with 10watt led fixtures...











"New" led rope light to supplement, added 3/19/16...











Grabbed a 10watt fixture off my fuge to help show color...




You can see in this pic that the right side was the last side I cleaned because alittle more light can show through...

I posted the wrong link in my previous post to the rope lights, this is the one I ordered, as this has the 660nm reds and the other was 626-630nm...
