The Real Cost of Light : Why LED Filament Bulbs Save More Than You Think

How Much Energy & Electricity Cost Can You Save with LED Filament Bulbs?

Comparing Incandescent, CFL, and LED (With Real California Cost Data)

Most people buy light bulbs based on price alone — but the real savings are in energy use and lifetime cost.
In this article, we’ll clearly compare Incandescent, CFL, and LED filament bulbs in terms of:

  1. Technology differences

  2. Annual electricity cost (based on California utility rates)

  3. Total Cost of Ownership (TCO) over lifetime

  4. Other quality factors beyond cost

  5. Why LafoHome EcoBright series excels

1. How These Bulbs Work: Technology Differences

 Incandescent Bulbs

Oldest lighting technology.
A tungsten filament heats until glowing. Most energy becomes heat, not useful light.

  • Low efficiency

  • Short lifespan (≈1,000 hours)

  • Warm light, but very wasteful

 CFL (Compact Fluorescent Lamp)

Gas discharge light: electricity excites mercury vapor → UV light → phosphor coating emits visible light.

  • Better efficiency than incandescent

  • Flicker & warm-up issues

  • Moderate lifespan (≈8,000–10,000 hours)

 LED Filament Bulbs

Modern solid-state lighting uses LED filaments to emit light efficiently with minimal heat.

  • High efficiency

  • Instant on

  • Long lifetime (15,000–25,000+ hours)

  • Warm ambient light without waste

LafoHome EcoBright Series uses high-efficiency chips + precision thermal design for brighter, longer-lasting light that feels great in homes.

2. Annual Electricity Cost Comparison (Same Brightness)

Let’s compare equivalent brightness (similar lumens) across all three types using California’s average residential electricity rate (~27¢/kWh in 2025†).

Bulb Type Wattage Equivalent Annual Energy Use* Annual Cost*
Incandescent 60W 60W × 1,000 hrs = 60 kWh ~ $16
CFL 13W 13W × 1,000 hrs = 13 kWh ~ $3.50
LED (EcoBright) 8W 8W × 1,000 hrs = 8 kWh ~ $2.20

*Assumes 1,000 hours of use per year per bulb.

LED filament bulbs use ~7× less energy than incandescent and ~1.6× less than CFL.
➡ That equals big electricity savings year after year.

3. Total Cost of Ownership (TCO) Over Lifetime

“Purchase price” doesn’t tell the whole story.
Let’s look at Total Cost of Ownership (TCO) — combining energy cost + replacement cost over a long period.

Example: 10-Year Scenario

Cost Component Incandescent CFL LED Filament (EcoBright)
Bulb Price (avg) $1.50 $3.50 $8-$12
Replacements ~10 bulbs ~2 bulbs ~1 bulb
Electricity (10,000 hrs) ~$160 ~$35 ~$22
Total Cost ~$175 ~$44 ~$32-$38

➡ Even though LED filament bulbs have a higher initial price, their TCO is dramatically lower than incandescent or CFL once energy and replacements are counted.

4. Beyond Cost: Other Important Lighting Factors

Savings matter — but comfort and performance matter too. Here’s how the bulbs compare:

✅ Warmth & Eye Comfort

• Incandescent: warm but inefficient
• CFL: cooler, sometimes harsh
• LED Filament: warm, flicker-free, low glare

Warm light is easier on the eyes in living spaces and helps relaxation in evenings.

✅ Dimmability

• Incandescent: dims smoothly
• CFL: often not fully dimmable
• LED Filament (EcoBright): excellent dimmability with compatible dimmers

✅ Color Rendering (CRI)

• Incandescent: very high CRI
• CFL: variable CRI
• LED Filament: high CRI for true, vivid colors

✅ Instant On

• Incandescent & LED: instant
• CFL: slow warm-up

5. Why LafoHome EcoBright Series Is a Smart Choice

The LafoHome EcoBright Series bulbs combine the best attributes of LED technology:

✅ Ultra-high luminous efficiency → lower energy use
✅ Warm and cozy lighting (2700K) → natural and relaxing
✅ Excellent dimming performance
✅ Long rated lifetime → fewer replacements
