I love them and Roy Deki swears by them and if they are good enough for him....
Most people like the HO because it is HO and it is a bigger toy, know what I mean, Heck, I have HO
Not that they are bad and there is a place for them, but over small tanks, I don't think it is needed.
And those Coralife's do a darn find job and are cool and SOOOO low profile and CUTE.
Check out this thread about true light needs from some real pro's http://www.aquascapingworld.com/foru...low-light.html
Really interesting and it reflects what I have to come to believe. Most of us strive for way too much light to really enjoy the scape (unless watching plants grow insanely fast is your enjoyment)
You can see some links to some of the posters tanks, I am talking 75 gallons with two T5 HO lights and that is all and the tanks are awesome. That is all I use of my Tek BTW over my 75 gallon.
I would not have gotten the 2 lamp fix, they cost almost the same and this gives me more options like mid day blasts, but I use mostly just the two lamps.
