i know one thing that ususaly gives you an idea of light quality is the colour of your corals and their growth. My mushrooms (red and purple, two hard colours to maintain) have actually gotten deep and brighter since i added these lights. I was going to switch out to guisseman's, but i think i will wait until they actually NEED replacing before i go out and spend another couple hundred bucks on new bulbs.
