The new 4W and 3.5 filament style candle LED should only be installed in visible fixtures. The standard 5W candle LED should be used in areas where you can not see the bulb.
LED Recessed Light Trim Kit Overview
Mass Save now offers LED Trim kits to help air seal recessed light fixtures from the interior.
Guidelines:

Install fee is $7.00 per kit
Trim kit includes the fixture and LED bulb
Trim kits are to be installed when replacing incandescent bulbs in recessed fixtures in ceilings under unconditioned attic space
Not eligible if exiting bulbs are LEDs or CFLs
Trim kits are intended to air seal recessed lights under unconditioned attic space, However, if you are installing them in a room that has both unconditioned and conditioned space above, you can replace all bulbs in that area with the trim kits or to satisfy customers’ aesthetic appeal.
Same rules apply for weatherization work – Recessed lights must be dammed off, and no insulation blown over them. Recessed light box covers are not needed
