60" DIY Cree LED Fixture (480watts) - Build Thread

Just a little bit of advise that i came across in my LED build is that if you run those drivers off your apex you will not have dimming down to zero. The only way to do it is with different drivers and separate power supply. My are still really bright when they first come on. Wish i had researched a little more when i did mine. Just a something to think about.

 

You're correct these drivers don't fully dim, in the data sheet it explains it. PWM goes down 15%, Analog down to 5% (oops 5% not 10% i originally stated) and LDD's are capable of dimming completely to 0% 8)

I opted out for the PWM just for this fact, and didn't want to use a power supply at the time but I think I should of in the end.

I could sell these drivers and buy the LDD's but I'm like to press on without them for now.

It's possible to get them quite low, but Meanwell ELN-60-48Ddrivers do have a minimum working point.

 

Well i defiantly am happy with my led build in general and i don't think that them not dimming to zero has any bearing on the tank but it was just an overlook of mine.

The build is looking awesome. Love the cables that you built and after i built mine i can sure appreciate the work that goes into building one.
