Rick, your LED rig looks great. Which one is it? And what's the coverage area? I will need higher power LEDs soon, hopefully something I can use for small Cattleya. I'm considering 2x Hans Panel to cover 4x2' area:

Like David said, wattage isn't everything with LED. Some makers advertise maximum wattage which the LED can handle, but they don't drive LEDs at a lower current (for the longevity of LED, and fine-tune the spectra). For example, so-called 3W LED may be actually consuming around 1.6W. Additionally, people seem to get good growth with good combination of colors and design, and Hans Panel seems to be pretty good with only 56 actual W.
I also prefer red-blue type of LEDs because the cost of electricity becomes pretty high once you have a fair number of orchids. But recently, grow light makers have been using white + Red (Area 51
LED GROW LIGHTS | Cree LED Grow Lights | American Made LED Grow Lights | Best LED Grow Lights is a popular one).
I also agree that grow tent is a pretty nice upgrade for people in North (fine control of humidity).
