The one H6024 (7" round hi/low Halogen sealed beam lamp) that consistantly gets the nod at Candlepower forums are GE's Nighthawk. (see this link for example).
You can search that forum to see if there is anything recent on the Wagners you're looking at, but my guess is that you won't find anything particularly positive. They are pretty good at keep the discussions about facts, factual.
