When you say the old one has on one side and two on the other what you are actually describing is switches. Place a stepladder under one the lights , climb it and remove the bulb.
If I replace those bulbs with LEDs, will that reduce the heat enough so I can insulate around the existing lighting cans?

Since you mentioned your cans have holes in them, they are most definitely not IC-rated. Airtight fixtures will be labeled. You can use a remodeling type to replace non-airtight fixtures.
Usually they will be IC rated ( insulation contact) as well. Not only do recessed can lights leak air, but warm lightbulbs also make the situation worse, turning the holes into small chimneys. The heat source accelerates the stack effect, speeding up the flow of air. We have recess lighting in the kitchen and bathrooms.

To prevent heated air from escaping around the hole in the ceiling on recessed light fixtures: Remove the bulb from the light fixture.
Pull the trim ring down a few inches from the ceiling. They still produce heat so use recessed fixture covers that are large enough to keep any insulation away from the heat source. Another major problem with older recessed light fixtures is air movement from the living space into the attic through the can light assembly.
I am hoping for some assistance in settling a debate among a few of my colleagues. IC-rated recessed lights OK with blown-in insulation ? Foil faced insulation : Foam, bubble or fiberglass. But the fixtures also can allow air, heat, and moisture to escape into unconditioned spaces. Split your insulation so half goes in front of and half goes behind electrical wires. Compressing insulation reduces its R-value.
Around electrical boxes, notch, rather than compress, the batt—then tuck the cutout behind the box. To help prevent frozen pipes, insulate only on the cold side. Do not confuse air leakage and a recessed light fixtures, as shown in Figure ability to have insulation touching it as one in the same thing. Can you put insulation around and on top of recessed lights ? Alternatively, the heat build-up caused by the covering insulation will hamper the efficiency of the can light.
Re: Recessed Can Lights And Spray Foam In Attic A lot of people are using spray foam in the attic now, but not on top of the sheetrock. Spray foam insulation is an air seal and works a lot better than “regular” insulation does. Because the spray foam doesn’t allow the heat to escape it can make in contact recessed can lights get very hot. Most can lights have a thermal overload to protect them from getting too hot.
