LED stands for Light Emitting Diode. It is a type of solid-state lighting that uses a semiconductor to convert electricity into light.
When an electric current passes through the semiconductor (the diode), it excites the electrons.
These electrons release energy in the form of light.
Unlike traditional bulbs that use heat to create light (like incandescent), LEDs emit light directly through the movement of electrons.
This makes them highly efficient and long-lasting
| 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 |
LEDs use up to 80% less energy than incandescent bulbs.
Lower electricity bills and reduced carbon footprint.
LEDs last much longer—up to 25 times longer than traditional bulbs.
Fewer replacements mean lower maintenance costs and less waste.
Lumen (lm): Measures the brightness of a light source. More lumens = brighter light.
Watt (W): Measures power consumption, not brightness. LEDs produce more lumens using fewer watts.
Example: 10W LED ≈ 60W incandescent
Lux (lx): Measures illumination level on a surface (lumens per square meter).
Used to measure how well-lit an area is.
CRI is a number from 0 to 100 that measures how accurately a light source shows colors compared to natural light (like daylight).
Higher CRI = Better color appearance.
In places like retail, art studios, hospitals, or homes, you want colors to look natural and accurate.
A CRI above 80 is generally good; 90+ is excellent.
