Things You'll Need
Recessed lighting offers the visual advantage of ceiling light fixtures that do not intrude into the room space. This allows the lighting to blend harmoniously with the room and helps create a sleek, modern look. When you have several recessed lights installed in one room, one possible and noticeable problem is when different bulbs have different depths, meaning that one or more bulbs sit deeper within their recesses while others sit closer to the ceiling trim. You can adjust the depths of the bulbs so that they are all uniform.
Flip the circuit breaker in the breaker panel that corresponds to the recessed lights to the "Off" position. This is for safety's sake.
Position a stepladder underneath the recessed light. Balance yourself on the stepladder.
Pry the recessed light fixture's ceiling trim cover off the fixture opening. Unscrew and remove the lightbulb. Fold a strip of duct tape back over itself and stick it to the bulb, if you are unable to insert your hand into the fixture to remove it. Twist the duct tape to unscrew the bulb along with it.
Use a non-contact circuit tester to confirm that the power is off. Reach up into the lightbulb's metal housing and loosen the wing nut. Slide the unit down or up, and tighten the wing nut.
Screw the lightbulb back into place, and reinstall the trim cover.
Flip the corresponding circuit breaker to the "On" position.
