Led lights

[Micro Reef Tank]

Hi everyone
Any feedback of this kind of led lights?

Anyone is using it?

Looks like the standard "black box" led light that is wifi controllable. They work and will grow pretty much any coral you throw at them. But be careful as these tend to be a powerhouse of focused light and can fry corals quickly.

Thanks for the feed back

How can we avoid it? “Fry corals” I mean.
Specially in a 4,5G Micro tank like mine.

Distance from top water ?
% of power if programmable ?
Number of hours on?

Mount them high and keep them turned down low. Check out this video by brs. Not the same light but the same concept

Will watch it

I will upgrade sooner or later to a bigger tank, and as my original led lights just broke I have to buy something to replace it if I can’t fix it

So I was thinking in buying this one that will setup the bigger one

Thanks again for your feed back

Most of the black boxes, as Op has posted, are rated at 165w’s. Far too much for a pico tank that is 4.5 gallons, even turned down to it lowest settings. The light spill would be significant.

I would look for another solution for a tank that size.

Thanks Flippers...

That’s why I posted here to know if there is a way to set it in a not so strong way and use it here wile waiting for the bigger tank

I read your last post after I replied and you could do it. You would have to keep it up high to avoid frying what’s in the tank. A par or at least a lux meter with conversion would be best to test light intensity over such a small tank. So it could be done.

I am going to research a little more how they work and are programmable then will decide

I am just trying to avoid spending money in a smaller weak solution then spend again for the bigger tank

I understand. I have three black boxes over my 125 gallon and they will grow anything very well. Not a bad light for the money.

That’s what I was trying to find out, someone that uses it with some real experience

Hi all. Just my 2 cents. Im an EE. I did some research online and built a set of LED fixtures using the no name "3W" LEDs off ebay. Based on the light spectrum over a tropical reef at the equator, I picked 465nm, 450nm, 410nm, and 10k wavelengths. Ive got 5 of each staggered on an rough extruded aluminum scaffold that I got from Home depot, one 18inch length for each side of a 55gallon. I control them with an arduino mega 2560 sending four individual pwm signals to CAT4100 series LED drivers from ON semiconductor. I limit the max current to 700mA, and the PWM to between 3% and 90%. I wrote code for the arduino that simulates the diurnal cycle of the sun and translated it to PWM duty cycle so the the LEDs automatically cycle throughout the day with max intensity at noon. I added a moonlight cycle as well using a real time clock. Sorry for the run on description, but to make a long story short, Ive had it running for about 8 months and have had great results. Corals adapt to their environment, if you choose the key wavelengths, 410, 450, 460nm, they can adapt and be happy. My corals are all frags and have at least doubled in size since I started using the LEDs.
