What bulbs were on in the post with 3 pictures above? I really like the look of your tank in those 3 pictures. The pics with all four lights on seems a little more washed and not as vivid or crisp in color as the tank with the 3 pictures.
I'm not the best to ask about LED
's because I've never had them, but I also plan on switching to LED
's after this 'round' of new ATI bulbs for my T5's. I just got them in today, and will post before and after pics.
So I'll probably have these new bulbs for just under a year, and then make the switch to LED
. I currently have higher temps in my tank because of the lights (and because they're in a canopy), so I always have 2 fans running. One in the canopy, and one across my refugium/sump to cool things off. It will be a lot nicer to have the 'wavelike' effect of the LED
's, plus the decrease in energy consumption, and less heat as well. But that's down the road for me...
