They seem to be out of stock at the moment though.
I have the Arcadia version, they work pretty well too

Any good reflector is better than none, but the big advantage of the gull-wing design is that it dramatically reduces re-strike. This is where light from the bulb ends up being reflected back into the bulb where it adds to the heat and inefficiency problems. If possible go gull-wing! It's only a tiny thing, but it all adds up IMO.
