Will a BR30 fit in a 4 inch can?
When choosing a bulb, you must find out the sizing of your recessed fixture can. For general household lighting, most recessed lighting cans are 4″, 5″, or 6″. If your household has 4” cans, only BR30 bulbs will fit. For 5″ cans, BR30 bulbs will fit with a little space, while a BR40 will fit with no space on the sides.
What size bulb for 4 can light?
