Funny I was thinking the positive locating and positioning was a plus.
But what of the point about being able to use existing reflectors?
Does anyone have a decent reflector that works well with the 315W?
If not, is there any interest in Open Sourcing the design for one?
If you want to use an existing reflector, just swap out the sockets. I'm using the Bell Lighting 600MV hoods, and they work great with the 315. The lamp is almost perfectly centered in the hood when installed.
