In my store the reflectors were with the outlets and switches but the Y adapters were somewhere else - weird.The aisle with lighting PARTS. (splitters, sockets, fixture boxes, etc.)
They can hold the adapter and two 26 watt bulbs. You need the 10.5" to hold two 42s.my bad if y'all consider this hijacking but is kinda relevant...
are the 8 1/2in clamp reflectors from lowes able to hold a y-adapter and two bulbs?
