Why choose LED lighting?
Lighting plays a crucial role in our daily lives, and technology in this area has advanced significantly. In this blog article, we will discuss the differences between incandescent bulbs, halogen lamps, energy-saving bulbs, and LED lamps. We will also highlight the benefits of LED lighting, including energy savings and a longer lifespan.
What are the differences between incandescent bulbs, halogen lamps, energy-saving bulbs, and LED lamps?
Below we have clearly summarized everything for you.
- Incandescent bulbs:
- Incandescent bulbs are one of the oldest and most traditional forms of lighting.
- They work by heating a filament until it emits light.
- Incandescent bulbs are inexpensive to purchase, but have a short lifespan of approximately 1,000 hours.
- They are inefficient and convert only 5-10% of the consumed energy into light, while the rest is converted into heat.
- Halogen lamps:
- Halogen lamps are an improved version of the incandescent bulb and are slightly more efficient.
- They use a halogen gas to extend lifespan and improve efficiency.
- The lifespan of halogen lamps typically ranges between 2,000 and 4,000 hours.
- However, they are still less efficient than modern alternatives such as LED lighting.
- Energy-saving lamps (CFL lamps):
- Compact fluorescent lamps (CFL lamps) are more energy-efficient than incandescent and halogen lamps.
- They work by illuminating a gas when an electric current passes through it.
- CFL bulbs have a lifespan of approximately 8,000 hours, which is significantly better than incandescent and halogen bulbs.
- Although they are more efficient than incandescent and halogen bulbs, CFLs do contain mercury, which is an environmentally polluting element.
- LED bulbs:
-
- LED (Light Emitting Diode) lighting is the most advanced and energy-efficient option.
- They work by passing an electrical current through semiconductors, emitting photons that produce light.
- LED bulbs have a much longer lifespan of an average 25,000 to 50,000 hours, resulting in less frequent replacement.
- LEDs are highly efficient and can save up to 90% in energy compared to incandescent bulbs.

Lifespan comparison of different types of bulbs
| Lamp Type | Energy Efficiency | Average Lifespan |
|---|---|---|
| Incandescent bulb | Low | Approx. 1,000 hours |
| Halogen bulb | Moderate | 2,000 – 4,000 hours |
| Energy-saving lamp (CFL) | Average | Approx. 8,000 hours |
| LED lights | High | 25,000 – 50,000 hours |
Which replacement wattage do I need?
What wattage do I need now to replace my traditional lighting? We received this question often. Therefore, below is a clear overview of how many lumens (light output) all traditional lamps contain compared to an LED lamp.
| Wattage | Incandescent bulb (Lumens) | Halogen bulb (Lumens) | Energy-saving lamp (CFL) (Lumens) | LED bulb (Lumens) |
|---|---|---|---|---|
| 5W | ~40-50 | ~90-100 | ~200-250 | ~300-350 |
| 10W | ~90-100 | ~180-220 | ~400-500 | ~500-600 |
| 15W | ~130-150 | ~250-300 | ~600-800 | ~800-1000 |
| 20W | ~200-250 | ~350-400 | ~900-1100 | ~1000-1400 |
| 25W | ~220-300 | ~400-500 | ~1000-1400 | ~1200-1800 |
| 40W | ~400-500 | ~700-900 | ~1500-2000 | ~3000-4000 |
| 60W | ~700-800 | ~900-1200 | ~2800-3500 | ~5000-8000 |
| 75W | ~920-1100 | ~1100-1400 | ~4000-5000 | ~8000-10000 |
| 100W | ~1300-1600 | ~1600-2200 | ~6000-8000 | ~10000-15000 |
Notes on the table above:
- The lumen values in the table are average estimates and may vary depending on the specific manufacturer and model of the lamp.
- LED bulbs generally have a higher luminous efficacy (lumens) per watt compared to other types of bulbs, which highlights their energy efficiency.
- The light output of LED bulbs can vary depending on the type and quality of the LEDs used in the bulb.
Several benefits of an LED bulb
- Energy saving: LED lighting is significantly more energy-efficient and can lead to substantial savings on your energy bill.
- Longer lifespan: The longer lifespan of LED bulbs means they need to be replaced less often, which saves costs in the long run.
- Environmentally friendly: LED E27 bulbs and LED E14 bulbs do not contain harmful substances such as mercury, unlike some other lighting options such as energy-saving lamps.
- Instant illumination: LED bulbs reach their full brightness immediately when switched on, unlike energy-saving bulbs that require some time to warm up.
Why choose LED lighting?
LED lighting is clearly superior to traditional lighting options such as incandescent, halogen, and energy-saving bulbs due to significant energy savings and a longer lifespan. Although LED lights have a higher initial purchase price, they pay for themselves in the long run through lower energy costs and less frequent replacements. By switching to LED lighting, we can not only lower our energy bills but also make a positive contribution to the environment by reducing CO2 emissions.
