1. Light source type
Series D halogen lamp: A tungsten filament bulb filled with halogen gas, emits light by heating the tungsten filament.
D-series LED lights: Use light emitting diodes (LEDs) as light source to emit light through semiconductor materials.
2. Energy efficiency
Series D halogen lamp: low energy efficiency, most of the energy is converted into heat, and the light efficiency is about 15-20 lumens/watt.
D series LED lights: high energy efficiency, light efficiency up to 80-120 lumens/watt, with significant energy saving effect.
3. Lifespan
D series halogen lamp: short lifespan, usually 1000-2000 hours.
D series LED lights: long life, up to 25,000-50,000 hours, or even longer.
4. Catalog
Series D halogen lamp: The heat generation is large and the temperature is high during working, so you need to pay attention to heat dissipation.
D series LED lights: low heat generation, low temperature, and low heat dissipation requirements.
5. Startup speed
Series D halogen lamp: fast start and light up when powered on.
D Series LED Lights: Start faster with almost no delay.
6. Environmental protection
Series D halogen lamp: contains a small amount of halogen gas, and needs special treatment after being discarded.
D series LED lights: No harmful substances, and are more environmentally friendly.
7. Cost
Series D halogen lamp: low initial cost, but high long-term use cost.
D series LED lights: The initial cost is high, but the long-term use cost is low.
8. Light quality
Series D halogen lamp: the light color is warmer, the color rendering is good, and it is close to natural light.
D series LED lights: adjustable light and color, excellent color rendering, and a wide range of color temperature.
Summarize
D series halogen lamp: suitable for scenarios with limited budget and high requirements for light quality.
D series LED lights: suitable for application scenarios that pursue energy saving, long life and environmental protection.
