Commercial Electric CER4742BZ Recessed LED Light- FAQs
What is the difference between a can light and a recessed light?
Both terms refer to similar fixtures, but can lights use a housing or “can” installed inside the ceiling, while canless recessed lights have a slim, integrated design. Canless versions are ideal for shallow ceilings, while can lights offer more flexibility in bulb types and sizes.
What is a recessed LED light?
A recessed LED light, also called a downlight or pot light, is a ceiling fixture mounted inside a hollow opening. It sits flush with the surface, creating a clean and modern lighting look.
Can I replace the bulb in an LED recessed light?
If the LED is built-in, it usually cannot be replaced. However, if your fixture uses a replaceable LED bulb, turn off the power, remove the trim, unscrew the old bulb, and install a new one of the same type and wattage.
Can I put insulation over LED recessed lights?
Yes, but only if the fixture is IC-rated. IC-rated recessed lights are safe to cover with insulation, while non-IC-rated lights need a small clearance to prevent overheating.
How long do LED recessed lights last?
Most LED recessed lights, including the Commercial Electric CER4742BZ, can last up to 50,000 hours (around 20–22 years) with regular use.
How many recessed lights do I need for a 12×12 room?
A 12×12-foot room typically requires about 6 recessed fixtures to provide balanced illumination, depending on brightness and layout preferences.
Can LED recessed lights cause a fire?
LED lights produce very little heat compared to traditional bulbs and are generally safe. Just ensure they are properly installed and rated for the application.
Do I need an electrician to install recessed lighting?
If you’re comfortable with electrical work, you can install retrofit LED kits yourself. However, for new wiring or ceiling modifications, hiring a licensed electrician is strongly recommended for safety and compliance.
What is the LED equivalent of a 60-watt bulb?
A 60-watt incandescent bulb is roughly equivalent to a 7–9-watt LED bulb, providing similar brightness with much lower energy use.
