Sorry Eric but I can not and will not discuss pricing with you here. This is a public forum.
As for the comparison between LED and Halogen fixtures... I have seen and tested some of the Kichler LED lineup. I prefer to use LED Lamps installed in top grade fixtures. Although the light output of the Kichler LED line up is very good, I have a big issue with the form that the fixtures take. I think they are ugly, poorly designed, and make use of sub standard materials. The knuckles and stems in particular are really really poorly designed and constructed. I am really unimpressed by them and think they will be a service nightmare down the road.
I would recommend you look at using "traditional" fixtures and install either halogen or LED lamps inside. Perhaps in the near future Kichler will re-think their LED line up and provide us with some products that do not put function in front of form.
