Exactly Greg. It's all about efficiency.

If you have .5 watt LEDs at 120 lum per watt that is better that 3 watt LEDs at 100 lum per watt if the total power is the same.

Holy, your statement that 3 watt LEDs is better than 0.5 watt LEDs is misleading. That statement origin is loosely based on the fact that MOST 3 watt LEDs tend to be higher quality than most .5 watt LEDs. But not always, and that is where your repeated statement is misleading.

It's all about TOTAL WATTS X EFFICIENCY.

Not sure how to start a new topic. New to this site. I need advice. Started this hobby 2yrs ago, my original tank, that was full of great stuff (bacteria, etc) wise & growing like crazy started leaking. I then upgraded to a 72g tank, which I'm having trouble with. Lost my favorite guy, my manderian and my blue tang. I figure not enough to eat in the new tank :-(

Bottom line, if they had stuck more powerful LEDs in the light unit being talked about, then the light would be more useful. As it stands, those fixtures are BARELY useful for planted tanks.
