LED stands for Light Emitting Diode. It is a semiconductor device that emits light when an electric current passes through it. The light produced is a result of electroluminescence — a phenomenon where the material glows when energized.
“Traditional light” usually refers to incandescent bulbs, halogen lamps, and sometimes fluorescent lights or compact fluorescent lamps (CFLs). These use older technologies like:
Incandescence (heating a metal filament until it glows)
Gas discharge (for fluorescents and CFLs)
| Feature | LED Light | Traditional Light (Incandescent, CFL) |
|---|---|---|
| Energy Use | Very low | High (especially incandescent) |
| Lifespan | 15,000 – 50,000 hours | 1,000 – 10,000 hours |
| Heat Emission | Very little | High |
| Light Direction | Directional (focused) | Omnidirectional |
| Durability | Strong, no filament | Fragile (especially incandescent) |
| Warm-up Time | Instant | CFLs take time to warm up |
| Cost (Initial) | Higher upfront cost | Lower upfront cost |
| Cost (Long-Term) | Saves money over time (less energy + replacement) | Higher electricity bills; more frequent replacement |
| Color Temperature Options | Wide range: warm to cool | Limited (incandescents = warm; CFLs = few options) |
| Dimming Capability | Most are dimmable (with compatible drivers) | Incandescents are dimmable; CFLs often not |
| Feature | LED | Incandescent | CFL |
|---|---|---|---|
| Wattage | 8–10 W | 60 W | 13–15 W |
| Lifespan | 25,000+ hours | 1,000 hours | 8,000 hours |
| Annual Cost (avg.) | ~$1.00 | ~$8.00 | ~$2.50 |
LEDs reduce carbon emissions by cutting down electricity use.
CFLs and fluorescents contain mercury, which poses disposal and pollution risks.
