LED vs Traditional Lighting: What's the Difference and What to Choose?
The Evolution of Lighting Technology
Over the past decade, LED technology has completely transformed the lighting market. Yet many people still use older technologies or don't know the specific advantages of LEDs. In this article, we'll compare LEDs with incandescent, halogen, and compact fluorescent (CFL) bulbs.
Energy Consumption
This is the biggest LED advantage. An LED bulb producing the same light as a 60 W incandescent uses only 8–10 W — an 85% energy saving. Over a year, a single LED bulb can save €15–20 in electricity compared to incandescent.
Lifespan
LED bulbs last 25,000–50,000 hours compared to just 1,000 hours for incandescent bulbs — that's 25–50 times longer!
Light Quality
Modern LED bulbs achieve CRI > 90, meaning near-perfect color accuracy. They also offer a wide color temperature range from warm 2700 K to cool 6500 K.
Environmental Impact
LED bulbs contain no mercury (unlike CFLs), are fully recyclable, and produce less CO₂ due to lower energy consumption. Switching from incandescent to LED in an average household reduces CO₂ emissions by about 50 kg per year.
How quickly does switching to LED pay off?
Take a home with 20 light points running about 4 hours a day at €0.25/kWh:
| Metric | Incandescent (60 W) | LED (9 W) |
|---|---|---|
| Annual consumption | 876 kWh | 131 kWh |
| Annual electricity cost | ~€219 | ~€33 |
| Replacements over 5 years | ~7 | 0 |
| Saved per year | ~€186 | |
Even if replacing all 20 bulbs cost €100, the switch pays for itself in roughly seven months.
What LED changed beyond energy
Incandescent and halogen lamps turn most of their energy into heat — enough to pose a burn and fire risk and to limit which fixtures they can be used in. LED runs barely warm, so it works in enclosed fittings, furniture niches and under cabinets. The second difference is control: LED dims smoothly, pairs with motion sensors and smart systems, and frequent switching barely affects its lifespan.

What to check before buying
- Lumens, not watts — a 60 W incandescent equals roughly 800 lm of LED.
- Colour temperature — 2700 K for living spaces, 4000 K for work zones.
- CRI ≥ 90 — so food, skin and interior colours look natural.
- Cap type — E27, E14, GU10, G9: check before ordering.
- Dimmable — the bulb must be marked as such if it will run on a dimmer.
How to read these off the packaging is covered step by step in our LED bulb buying guide.
Frequently asked questions
Is it worth replacing incandescent bulbs that still work?
Yes — over its remaining life an incandescent bulb burns more electricity than several quality LED bulbs cost, so waiting for it to fail loses money.
Why do some LED bulbs fail early?
Almost always for external reasons: surges, poor contacts, an incompatible dimmer or overheating in an enclosed fitting. The cause usually lies in the installation, not the bulb.
Summary
LED wins on every metric that matters: up to 85 % less energy, 25–50 times the lifespan, almost no heat and full control — with a payback of about six months. Browse our LED range or get in touch.
