I love my LEDs but am still struggling with the hardware. There's a story...
But first, our corals have had terrific growth with an older Solaris. I know now that this is meaningless, but when we bought it (craigslist), the guy said it was a "300 watt." We do need to keep the SPS in the top third of the tank which can be a drag, and I do want to upgrade. I'm going to be shopping because you can't beat LEDs for power use, low heat, and you still get some shimmer lines due to point source light. We actually got a little too enthusiastic and bleached some of our SPS by having too long a photo period. (They are recovering.)
Now if you care to hear a tale of woe, one of our ballasts went out a couple of months ago. A very nice guy rebuilt both of them but one refuses to work so we are still not using our Solaris - only half of the light works currently.
Soooo if anyone falls in love with an LED that won't require a second mortgage, do tell!
