Default DIM4 Sunrise/Sunset controller for DIY LEDs by LEDGroupBuy.com

If you haven't heard already, we just released the DIM4 Sunrise/Sunset controller for DIY LEDs.
Its designed by an engineer that is also a reefer and LED expert.

Its designed to control 4 channels of:
3 CREE XP/XM LED string (@500mA)

What does that mean to you? For every channel on the DIM4 (4 channels) you can either have a bunch of drivers on each channel or 3 CREE XP/XM LEDs in a string or fans to cool your heatsinks. If you are just doing the 3 LED strings or fans, you do not need any additional drivers. (Yes! your moonlight issue just got solved)

Some examples of configurations:

Nano config
Channel 1 - 3x CREE XM-L Neutral White
Channel 2 - 3x CREE XM-L Neutral White
Channel 3 - 3x CREE XP-E Royal Blue
Channel 4 - Blank
(Any channel above can also be used for moonlights)
(2A Power supply or greater needed)

Large tank config
Channel 1 - 1x 120w Inventroincs driver for Neutral Whites
Channel 2 - 2x 40w Inventroincs driver for Royal Blues
Channel 3 - 3x 120mm Fans to cool heatsinks
Channel 4 - 3x CREE XM-L Neutral White for moonlights
(2A Power supply or greater needed)

And..... are you ready for this? NO PROGRAMMING NEEDED. Through the LCD screen you set a 5 things per channel. Max Driver current (for direct driven LEDs), Start time, Full on time, End Full time, Offtime. Through these 5 settings the controller will know when to turn on (Sunrise), when to get to the max (end of the sunrise), when to start dimming (sunset), and when to turn off (end of sunset). This is very different than the arduino based controllers where you have to actually type in code via a computer - no computer needed.

If you have questions or comments please post them on this thread so we can get them answered for you.
