I hybrid is pricey, but it's the best light for SPS without a doubt.
I used Giesemann Spectra w/400W Radium. Great lights, but these are better in that you can adjust the colour spectrum for different corals and colours. With Radiums, you can't. SPS also grow towards the bulb, which they don't with T5.
I feel the strength of LED is in growth. Not so good for colour, so the ATI Hybrid has the best of both worlds. Really pleased with theses lights.

Besides shimmer though what benefits do you gain from the LEDs. Since like a power option is all T5s which I have run in the past and thought worked well. When you consider a sunpower for $550 verus a powermodule hybrid for $1800 seems hard to justify.
