Yeah, I have mines dialed in @ 700 mA for both white and royal blue.

I need some help troubleshooting a MeanWell. I am trying to light 12 CREE XR-Es with a MeanWell Eln-60-48-D. How do I set it up initially?
The LEDs are wired in series, then the V+ is wire to the terminal + on the LED and the V- is wired to the terminal - on the opposite LED. When I plug it in only half of the leds light and only for a very brief moment and dimmly. What am I missing?

how can i test if i have a bad led??? I would like to test it on its own as i have a series of lights out and don't know what light is bad...

AndyReef,
Driving the XREs at 1A doesn't decrease their lifespan as that is their rated current. Their lifespan would be decreased if the heat produced from the LEDs is not dissipated.
As a rule of thumb, we typically consider for electronic circuits that for every 10C rise above rated maximum temperature of a device, MTBF decreases by 50%. So, it is very important to ensure that there is adequate convection cooling or forced air cooling so that the LEDs do not run too hot.
Reducing the current to the LED will result in less heat production and is appropriate/effective if the heat sink and cooling system are undersized.

I'd like to know what considerations I need to keep in mind when wiring up the leds to make sure they can be controlable, such as with the profilux contrroller or if possible some other sort of computer (pc) controlled software. From what i saw in a youtube 7 part review of the aquaillumination profilux controller combo and that there is another led wired for the profilux, does anyone have any recommendations as to how to wire them up ? I'm assuming already that the white and blues are all wired seperatly, from what I see in the youtube video.

Another question in regards to lighting controllers;
i just did a bit of research and came across dmx light board controllers. Are these feasible to use on a reef led system? they seem much more powerful ( the pc based ones) whi start around 379 on google shoping. it just seems like you'd get more control with a unit like this vs the profilux.. of course you'd need to buy more drivers and have smaller banks to really mske it noticablebut would probably have the ability to sync audio weather effects with visual ones.
The less powerful (non pc/software) controlled units start at like 79 and could be mounted and would be like the controller interfaces on many led light systems, but larger with more controls.

that is a link to part 1, there are 7 parts, the good tsuff is in later videos/parts

I have seen a few people with glass shields, but i'm not sure if that was permanent or just for demonstrating the LED's on their corals. I will be raising my arrays high enough to prevent splashing and good circulation for moisture or at least that is my plan.
