I don't question that.
I just found that some folks (not necessarily aquarists who have done a lot of research) have really high expectations when spending big bux on LED lights. And then comes the harsh reality when they realize that they are not all that cool running as advertised, and that 3W LED doesn't really replace that 20W Halogen light.
There was a huge increase in efficiency back when fluorescent lights replaced incandescent bulbs. I think many expect LEDs to be a similar jump in efficiency and energy savings. They are a big jump in technology, but don't expect your energy bill to be drastically reduced, and pay off the initial investment in a few months.
Don't get me wrong, I love everything LED, and admire your projects. Just like to play devils advocate.
