Do recessed LED lights get hot?
Answer: While LEDs run much cooler than incandescents, their electronic components and external heat sinks do get quite hot; you would still need to keep the insulation away from your fixtures. … You could hire an electrician to replace each fixture with a sealed one rated for insulation contact (IC).

Can recessed lights cause a fire?
But when not properly installed, recessed lighting fixtures can overheat. If their external temperatures go beyond 194 degrees Fahrenheit (90 degrees Celsius), a fire can result. This is often due to bad wiring or the fixtures being in contact with combustible materials or insulation.
Can you insulate over recessed lights?

How do you tell if a recessed light is IC rated?
Look into the inner bulb chamber of the fixture to find the Underwriters Laboratory rating sticker, which is typically on the metal housing near the opening. This sticker will define the fixture’s rating (IC or NON-IC) and the approved maximum bulb wattage.
When installing type non IC fixture thermal insulation shall not be installed within of the top or of the side of a recessed luminaire fixture?
Clearances for Recessed Luminaries that are Non-Type IC: Thermal insulation shall not be installed above a recessed fixture or within 3 in. (76mm) of the recessed fixture enclosure, wiring compartment, or ballast, unless it is identified for contact with insulation, Type IC.
When installing a type non IC fixture thermal insulation shall not be installed within?

What is electronic ballast for fluorescent lights?
In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw.
Where is ballast in fluorescent light?
Locate the wiring cover plate, usually in the center of the fixture. On either side of the cover, there will be tabs that catch in slots in the fixture. Squeeze the sides of the cover inward to slip the tabs out of the slots, and pull the cover down. This will expose the ballast and its wiring.
Do electronic ballasts contain PCB?
