How to Pick the Right Light Bulb for Recessed Lighting

What Makes Recessed Lighting Special

Recessed lighting, sometimes called "can," "pot," or "downlighting," refers to fixtures installed into the ceiling so that the body of the light is hidden. Only the trim and bulb are visible, offering a seamless finish ideal for kitchens, living rooms, offices, and hallways.

Why Choose Recessed Lighting

• Unobtrusive look that works with any décor
• Even light distribution for workspaces or general illumination
• Zone lighting options for highlighting art, countertops, or room features

Types of Recessed Fixtures

1. IC-rated vs. Non-IC-rated: IC (Insulation Contact) rated fixtures are designed for direct contact with ceiling insulation. Non-IC-rated fixtures require a gap for safety.
2. Use-specific trims: Options include baffle (reduces glare), reflector (maximizes light), and adjustable/gimbal (directs light where you need it).



Understanding your fixture type is the first step to making your lighting work for your space.

The Big Questions When Choosing a Light Bulb

Not all bulbs are created equal! Here’s what you should consider before buying:

Bulb Type

LED bulbs are the top choice for most homeowners and electricians. Here’s why:



• Use up to 80% less energy than incandescent bulbs
• Lifespans ranging from 15,000 to 50,000 hours
• Cool operation reduces fixture and attic heat

Halogen bulbs are less efficient but produce bright, crisp light and excellent color rendering. They’re sometimes favored for task lighting or where vivid colors matter.

Incandescent bulbs are inexpensive but far less efficient. Most homeowners are now transitioning away from these due to the high energy consumption and short lifespan.

Brightness (Lumens)

Watts measure energy; lumens measure brightness. The higher the lumens, the brighter the light.



• Kitchen or workspace: 800–1200 lumens per fixture
• Living room or hallway: 600–800 lumens per fixture
• Bedroom or soft accent: 400–600 lumens per fixture

A common mistake is to buy based on wattage instead of lumens. With today’s energy-efficient lighting, watts are no longer a reliable guide!

Color Temperature (Kelvin)

The color temperature (measured in Kelvins or K) shapes the mood of your space:



• 2700K–3000K (Warm White): Cozy, inviting, perfect for living areas and bedrooms
• 3500K–4100K (Cool White): Bright and energetic, ideal for kitchens or workspaces
• 5000K–6500K (Daylight): Crisp and vibrant, useful for garages, laundry rooms, or task-heavy environments

JP Electric and Son recommends matching the color temperature to the room’s purpose for the best experience.

Bulb Size and Shape

Bulbs for recessed fixtures commonly include:



• A19: Standard bulb shape, good for larger cans but may look out of place in most recessed fixtures
• PAR30/PAR38: Focused, directional lighting for higher ceilings or spotlights
• BR30/BR40: Broad beam, ideal for general purpose or lower ceilings

Always check the maximum bulb size recommended by your fixture manufacturer. Using the wrong size can impact lighting performance and even safety.

Energy Efficiency

Energy-efficient bulbs are a win-win for your home and wallet.



• LEDs cost a bit more upfront but pay for themselves several times over through savings on your utility bills
• Rebates may be available for switching to LED bulbs in Massachusetts
• Less frequent bulb replacement equals less maintenance and fewer trips up the ladder

JP Electric and Son can help Fitchburg homeowners make the switch to high-efficiency lighting for the best results long term.

Five Steps to the Perfect Bulb

Choosing the right bulb is simple if you follow this step-by-step guide:

Step 1 Identify Your Recessed Fixture

• Is it an IC or Non-IC fixture?
• What trim type?
• What size (4”, 5”, 6”)? This impacts the bulb shape and wattage you should use.

Step 2 Determine Required Brightness

• Think about the function of your room.
• Match lumens to your needs (use our guide above for reference).

Step 3 Select Color Temperature

• Decide if you want warm, neutral, or daylight tones.
• For open-plan houses, consider whether adjacent rooms should have the same or different color temperatures.

Step 4 Choose Size and Shape

• Check your trim and fixture specifications.
• Pick a bulb compatible in both physical size and beam angle.

Step 5 Consider Efficiency and Long-term Costs

• Lean toward high-efficiency LEDs for savings and convenience.
• Ignore the old watt-based habit in favor of lumens and listed life hours.

Avoid These Frequent Mistakes

Even experienced DIYers can get tripped up by these errors:



• Using the wrong wattage: Overpowered bulbs can overheat the fixture, causing fire risks or damage.
• Ignoring color temperature: This can leave rooms feeling too harsh or too dim for their meant purpose.
• Overlooking bulb size and shape: This can result in bulbs sticking out, not fitting, or dispersing light incorrectly.
• Neglecting energy efficiency: Cheaper upfront may mean higher bills for years.

Installation and Maintenance Tips

A little care during installation can extend your lighting’s life and keep your home safe:



• Switch off power at the breaker before removing or installing bulbs.
• Use a sturdy ladder and avoid overreaching.
• Handle bulbs with care: Oils from your hands can shorten the life of halogen bulbs, and dropping an LED can disrupt its circuitry.
• Dispose of old bulbs safely: Many localities (including MA) have recycling for old LEDs and banned incandescents.
• Wipe down trim and bulbs periodically to remove dust and maintain maximum brightness.
