Get to Know the Difference Between Several Common Lamps!

CANCO as a leading manufacturer of circular LED lighting fixtures, our company is committed to providing high-quality, energy-efficient lighting solutions to our customers. With the increasing demand for eco-friendly and cost-effective lighting options, it is essential to understand the advantages and disadvantages of different types of lighting fixtures available in the market. In this article, we will discuss the differences between incandescent lamps, fluorescent lamps, energy-saving lamps, and LED lights.

1. Incandescent Lamps

Incandescent lamps, also known as light bulbs, work by passing an electric current through a filament (made of tungsten with a melting point of over 3000 degrees Celsius), which produces heat. The filament’s spiral shape continually accumulates heat, causing the filament’s temperature to reach over 2000 degrees Celsius. When the filament is in the incandescent state, it emits light, much like red-hot iron. However, only a tiny fraction of the electric energy (possibly less than 1%) is converted into visible light, while the majority of the energy is wasted as heat.

Incandescent Lamps


  • The incandescent lamp is small in size and low in cost. The size of the illuminant can be made very small, making it compact in structure and low in cost.
  • Incandescent light is soft and uniform, has good color rendering, and produces the effect closest to natural sunlight.


  • Incandescent lamps are not environmentally friendly as 95% of the electric energy consumed is wasted as heat.
  • The lamps’ high operating temperature leads to rapid evaporation of the filament, resulting in a shorter lifespan.
  • The general lifespan of incandescent lamps is only 3000~4000h, which is shorter than that of fluorescent lamps.

2. Fluorescent Lamps

Fluorescent lamps, also known as tube lights or CFLs, work by discharging a small amount of mercury vapor in a sealed glass tube, which produces ultraviolet light that excites a phosphor coating on the inside of the tube. The phosphor coating emits visible light, resulting in the illumination of the lamp.

Fluorescent Lamps


  • Fluorescent lamps are energy-efficient as they convert about 60% of the electric energy consumed into visible light, while the remaining energy is wasted as heat.
  • They have a longer lifespan than incandescent lamps.


  • Fluorescent lamps have lower color rendering properties than incandescent lamps, resulting in less accurate color reproduction.
  • They also have a more deadly point – strobe. Of course, as long as the gas discharge lamps have strobe phenomenon, which is caused by the cycle of current changes.

3. Energy-saving Lamps

Energy-saving lamps, also known as compact fluorescent lamps (CFLs), have high light efficiency (5 times that of regular bulbs), significant energy-saving effects, long lifespan (8 times that of regular bulbs), small size, and easy installation. They work similarly to fluorescent lamps, but they are designed to be smaller and more compact.

Energy-saving Lamps


  • Energy-saving lamps are highly efficient, converting about 5 times more light per watt than incandescent lamps.
  • They also have a longer lifespan than traditional bulbs, which makes them more cost-effective in the long run.


  • Energy-saving lamps have lower color-rendering properties than incandescent lamps.
  • They may pose health risks due to the presence of mercury.

4. LED Lights

LED lights (Light Emitting Diodes) are a type of solid-state semiconductor device that can directly convert electrical energy into light. The heart of an LED is a semiconductor chip that is attached to a support and encapsulated in epoxy resin. The chip consists of three parts: a p-type semiconductor, an n-type semiconductor, and usually 1 to 5 quantum wells. When a current passes through the wire to the chip, electrons, and holes are pushed into the quantum wells, where they recombine and emit energy in the form of photons, resulting in the emission of light.

LED Circular Lights


  • LED lights have High energy saving, DC drive, ultra-low power consumption electro-optical power conversion of close to 100%, and the same lighting effect can save more than 80% energy than traditional light sources.
  • Long service life. Under proper current and voltage, the service life of an LED lights can reach 100,000 hours, which is longer than other types of lamps.
  • LED lights have Environmental protection and no harm from metal mercury, thus safe for long-term use.


  • LED light’s initial purchase cost is relatively high.
  • LED lights also heat up and require heat dissipation.
  • The LED light source is very directional, and the design of the lamp needs to consider special optical characteristics.

In conclusion, the pros and cons of each type, as well as their specific lighting needs, should be considered when deciding which luminaire lighting option to use. At Canco Lighting, we specialize in LED Circular Light design and manufacturing and provide high-quality LED lighting fixtures with industry-leading components to ensure reliability. We work to reduce glare, optimize light output, render the purest colors, and ensure efficiency within our products so that in turn, using and depending on our lighting and design is easy and carefree for the products’ lifetime.
