To Good To be True -ES Cree 60W Pro LED Strip

Would be good to find out the mA that each led is receiving, because its not just the crees that make a good fixture, also need quality drivers, wiring, fine tuning, ect.

It would be hard to believe that using 50 or 100 3w crees someone couldn't grow SPS directly below them.

 

Here is info from Advance Aquarist: E.Shine Systems' 60W CREE enters the aquarium LED arena ... sort of — Advanced Aquarist's Online Magazine

and from E-Shine themselves: 60W CREE LED Aquarium Light - LED Grow Light, LED Aquarium Light, LED Lighting...

Eshine Lights

If people are interested they can contact me. I have a connection at Eshine for lights.

 

Quonne, if you have a connection please let me know what type of driver and the power that they use (trying to compare it to a dimmable Meanwell drivers). When I talked to Vicky and Morgan last night, they couldnt tell me anything other than they make their own drivers.

 

They do make their own drivers, WHY is that bad? You can get them dimmable but it will cost more as with any dimmable light. You can controll the lighting sequence blue on/blue off white on/blue and white both on/blue off white on/blue on white off.
Why do you want dimmable lights.

 

I don't think he was saying it was bad. However, them making their own drivers with 0 info available to the public, and with comments like "they couldn't even grow SPS directly below them" really opens the door to what voltage they run their LEDs at. Without any information, as far as we know, they could be running them at much lower voltage and them be "on" but basically worthless. Further, if you have an emitter that lasts ~7 years, and a driver that will last ~1 year, why dump the money in? May as well get something that will last, if you see my angle.

As for being dimmable, well, I'll just hit the high points.
1.) Control over sunrise/sunset
2.) Light acclimation of corals, as well as, setting the max value that your emitters run at. (Some people like to only run them maxed out for a couple hours a day, and run them much lower for the remaining photo period.)
3.) Control over Blue/White blend. Some people like the 10k look others the 20k, this gives you the ability to do such.

 

Why would I want dimmable lights? Cause I want to control the brightness, the way they look(i.e. color) etc. On top of that once I start growing corals i rather turn the lights down rather than adjusting the height of the lighting fixture.

No it's not bad that the company makes their own diver. But when a customer has a simple question that their customer service doesnt know anything about (other than they make their own driver), then yes I do think that is bad.

 

For the dimmable function,
As you can see in the brochure of the 48x3W programmable led aquarium light, there are five buttons on the controller, and people could set the light intensity of blue and white separately for each hour of a day. For blue or white, people could adjust the intensity from 0-100%, and every 10% is a level.
For example, there are 24 hours in a day, and people need to set the light for each hour.like this:
0:00-1:00 Blue 20% White 0
1:00-2:00 Blue 30% White 0
2:00-3:00 Blue 40% White 0
3:00-4:00 Blue 50% White 10%
4:00-5:00 Blue 60% White 20%
5:00-6:00 Blue 70% White 30%
6:00-7:00 Blue 80% White 40%
.......
People could change the intensity of blue and white separately for each hour as they like, and once the program is set, the light will work according to the program everyday.

For the CREE leds, we drive them at 3.2-3.5V, 700mA-850mA, we provide 2 years warranty for our power driver, in current market, even if the life span of the the leds is be claimed for 5 years, but the led driver never last the same life as leds, we're manufacturer, up to now, no led driver factory dare promise their power drive the leds good for more than 2 years.


I hope this answers some of the questions on Eshine lights. I love these lights.

 

3 AI sol will light up your 72" tank beautifully!! You will need to be able to mount them high, around 14". If you can do that, you won't have any problem with 3 units.

 

How would 3 AIs light up a 6' tank? They have 40degree optics and are 70W each. They really won't give good par for much over 1 linear foot. For a 6' tank you need 5-6. TAN(Lens angle / 2) * distance * 1.5 (using 1.5 to adjust for drop in PAR to edges). So, even raised 24", your only getting about 13" of good coverage.
