I really like the idea of being able to have a close to true sunrise sunset light setup. Saw this posted on RB. Still way to expensive I'm guessing. Price isn't out but sounds like it'll be $1500 per 180W module. Such BS that there is such a disparity in costs. Buy chinese or pay 10x the price for anything else!

That AI LED module I picked up does all of that including lightening strikes, but price ultimately depends on how many units you need... Well might not do moving clouds (only have 1 unit) but it does dim for thunderstorms.

Sol, got 1 unit and controller for 565 shipped. Talked George at ReefGeek down a little retail is 602 for the pair, or 629 with mounting hardware.

Don't worry the Chinese will steal the technology like they always do.

I'm surprised that they don't already. Chris you ought to ask your guy's if they could put a controller in one of your models!

I meant a controller of a dimmable LED driver. That way the light fades in and out. That arduino would just shut off and on wouldn't it?

The arduino uses PWM to send a signal to the LEDs in order to control the brightness level. If the system were capable of using this technology in theory it should be able to dim it up and down at a set time/rate

Huh, didn't know it could do that! I wonder how that compares to true dimming via current? I would imagine you could perceive a flicker.

it manages to pulse it fast enough so that the eye can't perceive it. At least that is what I have read, have yet to see it in person, but am hoping to get one built for my LEDs within the next few months.

SpaceOps built a controller like this for his DIY LED unit.
