Well, it’s been about a year since I built my LEDgroupbuy light. I’ve gradually increased the LED intensity from 35% to 60% and am very happy with the results. I may boost the intensity up a little bit but I don’t think much. The only coral I have that seems to not be as colorful is the hammer coral which looks a little lighter. The clams seem to be very happy which makes me happy! 🙂
The only issue I’ve run into is that one of my MakersDRIVERS 5UP PRO units gave out here last week. I came home and noticed all the LED chips but one were off (far right on). I turned the lights off for a bit and then back on. All the Lumia chips fired up but the right side of my tank looked darker and more actinicly lit. The left side of the tank was bright and white. Turns out that when the MakersDRIVER went out it stop communicating to the other 5UP PROs down the line and the result was each Lumia chip down the line was running at a 100%. This could have been a bad deal for the coral, jumping from 60%-100%, but they weren’t too upset. I dug out an old window screen and placed it over the left side of the tank which seemed to filter out enough light to look consistent with the 60% output.
After the 5UP PRO went out I looked at the LED Group Buy website and saw the 5UP PROs only had a 90-day warranty… Fortunately after emailing LED Group Buy they priority mailed out a replacement at no cost. 🙂 I’m glad I went with a company who stands behind their, and their supplier’s, products!
Here’s what the light looked like after I restarted it (evening). The sunrise/set controller plugs in on the right and daisy chains to the left. The second set of lights you can see are out and all chips to the left are running at 100% :-/.
Even though the power was turned off to this 5UP Pro it still had about 1% power going to channel 3. I assume the Makers sunset/rise dimmer sends a little power through the audio cables.
Notice the burn spot between the fuse and fan wires. I’m guessing this is where the issue was.
Back up and running!
Happy fish and clams!
