LED lightbulbs are energy-efficient, long-lasting, and versatile. However, choosing the right bulb can be tricky due to the new terminology and features. Here’s what you need to know:
Energy Efficiency
- LEDs use 75% less electricity than incandescent bulbs and emit less heat.
- A 60-watt incandescent can be replaced by a 10-watt LED, saving on your electric bill.
How They Work
- LEDs use tiny electronic semiconductors to produce light, converting about 90% of energy into light, unlike incandescents which waste energy as heat.
Brightness (Lumens)
- Lumens measure brightness, not wattage.
- Quick Reference:
- 100W incandescent = 1,600 lumens (look for this number when shopping).
Lighting Hue (Kelvin Scale)
- Kelvin (K) measures light color:
- 2,700–3,000K = Warm, yellowish light (similar to incandescents).
- 4,000K+ = Cool, bluish light (ideal for task lighting).
- Ignore vague labels like "soft white"; rely on Kelvin numbers for accuracy.
Color Rendering Index (CRI)
- CRI measures how accurately colors appear under the light:
- Aim for 90+ CRI for vibrant, natural colors.
- High-CRI bulbs may cost more but offer better quality.
Dimmability
- Not all LEDs dim well; look for “dim-to-warm” bulbs for a cozy glow.
- Check compatibility with your dimmer switch to avoid flickering or noise.
Lifespan
- LEDs can last 25 times longer than incandescents, but check warranties for realistic expectations.
Smart Lighting
- Tunable White Bulbs: Adjust hue via a smartphone app for different times of day (e.g., cool white for work, warm light for relaxation).
- Automation: Set lights to mimic natural sunlight for better sleep and mood regulation.
Task-Specific Options
- Warm Light: Great for living rooms and bedrooms.
- Cool Light: Ideal for offices, kitchens, or workspaces.
Stick to a Brand
- Using one brand throughout your home ensures consistent color temperature and quality.
Check for Discounts
- Many utility companies offer rebates or discounts for Energy Star-certified LEDs.
Recycle Properly
- Dispose of used LEDs at stores like Home Depot or local recycling centers.
