The light source is the heart of any projector, directly determining its brightness, color quality, and lifespan. Confused about the differences between lamp, LED, and the latest laser technology? FordStampInc gives you a deep dive into the pros and cons of each.
1. The Classic: High-Pressure Mercury Lamp
This is the traditional and most common technology.
- Pros: Very high brightness output, low initial cost.
- Cons: Short lifespan (typically 2,000 to 5,000 hours), brightness fades significantly over time, and requires costly replacement bulbs. Generates considerable heat.
2. The Long-Life Champion: LED (Light Emitting Diode)
LED technology has revolutionized the compact and smart projector market.
- Pros: Ultra-long lifespan (up to 20,000 to 30,000 hours), excellent color performance (wide color gamut), low heat, and instant on/off.
- Cons: Historically, the brightness ceiling is lower than lamp or laser (though constantly improving).
