It really annoys me that they can't use existing cobrahead shells for induction. I mean, AEL and GE offer the 125 and M-400 in induction and Cooper makes the OVH and OVF in LED so why can't others make "real" induction and LED fixtures instead of these eyesores?
US lighting tech does make a "Cobra" style fixture using the Icetron type lamp. I haven't gotten any pictures of the ones they installed in Corona yet but I'll try to the next time I'm in the area.
