The Case for Switching to LED
A standard 60-watt incandescent bulb costs about $1.00 and lasts 1,000 hours. The equivalent LED (800 lumens) costs $2–4, uses 8–10 watts, and lasts 15,000–25,000 hours. Replace all the bulbs in a typical home with LEDs and you'll save $200–500 per year on electricity while never buying bulbs for 15+ years. It's one of the simplest home improvements with guaranteed positive ROI.
Understanding LED Specifications
Lumens (Not Watts)
Watts measure energy consumption, not brightness. Lumens measure brightness. For LED shopping:
- 40W incandescent = 450 lumens LED
- 60W incandescent = 800 lumens LED
- 75W incandescent = 1,100 lumens LED
- 100W incandescent = 1,600 lumens LED
Color Temperature (Kelvin)
- 2,700K – 3,000K (Warm White): Cozy, yellowish light. Best for bedrooms, living rooms, dining rooms
- 3,500K – 4,000K (Neutral/Cool White): Clean, crisp white. Best for kitchens, bathrooms, offices
- 5,000K – 6,500K (Daylight): Bright, slightly blue-white. Best for garages, workshops, task lighting
CRI (Color Rendering Index)
CRI measures how accurately a light source renders colors compared to natural sunlight (CRI 100). For living spaces, look for CRI 80+. For bathrooms and kitchen prep areas where you need accurate color (makeup application, food prep), choose CRI 90+.
Best LED Bulbs by Room
Living Room and Bedroom: Philips 60W Equivalent Soft White (2-Pack)
Philips' standard A19 LED at 2,700K delivers a warm, inviting glow that matches incandescent light. Dimmable with most standard dimmers. At $8–12 for a 4-pack, they're the best value for living spaces. CRI 80.
Kitchen and Bathroom: GE Relax HD 60W LED Soft White
GE's Relax HD series uses a proprietary filter that makes skin tones look natural under the light — important for bathroom vanity lighting. The 2,700K color temperature is warm enough for comfort but bright enough for task work.
Garage and Workshop: Hyperikon 5000K LED Daylight Bulbs
For garages and workshops where you need to see what you're doing clearly, 5,000K daylight bulbs eliminate the amber cast that makes it hard to distinguish colors and details. Get the highest lumen output (1,600+ lumens) your fixture supports.
Smart Bulbs: Philips Hue White A19
If you want to control lights from your phone, set schedules, or use voice control with Alexa/Google Home, Philips Hue is the most reliable smart bulb ecosystem. The starter kit includes the Hue Bridge and bulbs. Once you're in the ecosystem, controlling every light in your home from your phone becomes straightforward.
Dimmer Compatibility
Not all LED bulbs are dimmable, and dimmable LEDs require an LED-compatible dimmer — your old incandescent dimmer may cause flickering or humming. Lutron and Leviton make excellent LED-compatible dimmers for under $20. Always check the bulb packaging for the "DIMMABLE" label if you plan to use a dimmer.
