I have the !0W, 20W and 30W lamp bulbs with my kit (the extra bulbs were quite expensive from Pagstore). I notice that hardware stores do multipacks of similar 6V halogen bulbs much cheaper. I was wondering if they were of inferior optical quality and produced uneven light. Any thoughts?

I've used store brand MR-16's in ultra lights and coolights without a problem. mainly you have to pay attention to wide, medium, spot. other then that, they have worked fine
