Answer:
This is the question that most customers ask when they are introduced to or use LED lights for the first time. You should choose to use this type of light because compared to conventional lights, they have many advantages:
– Continuous light emission, no flicker
– Good light quality
– Energy saving: LED lights consume 80-90% less energy than incandescent bulbs of equivalent brightness. Let’s see the comparison chart below:
Đèn sợi đốt Đèn LED
25W 3W
40W 4-5W
50W 6-7W
60W 8-9W
75W 10-12W
100W 15-20W
120W 20W

2. How much will I save if I use LED lights?

Answer:
Energy saving is still the top concern of users when choosing to use lights. Therefore, this will be the question of most customers.
If an 8W LED is used to replace a traditional 60W incandescent bulb, and the bulb is operated for 8 hours a day for a year (2,920 hours), the electricity consumption will be reduced by 152 kWh per year. Therefore, the homeowner will save VND 304,000 per bulb per year (assuming the electricity price is VND 2,000/kwh). If the house has 20 bulbs, the customer will save VND 6,080,000 per year.

3. How long does an LED light last?

Answer:

A good quality lamp always has a long life, so many customers wonder about the life when buying LED lamps. The lamp has a life of up to 50,000 hours, much higher than the 1,000 hours of traditional incandescent bulbs and 10,000 hours of compact fluorescent lamps.

 

4. LED lights are very expensive. So is it really economical to use LED lights?

Answer:
High cost is a weakness of LED lights compared to conventional lights, especially when approaching the family customer group.
The initial investment payback period of LED bulbs is 1 year, after which you will save about 304,000 VND in electricity consumption per bulb (replacing a 60W bulb) per year. In addition, you will not pay for the cost of replacing incandescent bulbs every 1,000 hours or the time spent replacing bulbs in case the lights are installed in places that are difficult to replace.

5. Why should I switch from compact fluorescent lights to LED lights?

Answer:
This is probably the first question in the LED Q&A section of many customers when they have decided to choose LED instead of fluorescent for indoor lighting.
First, the lamp is 30-50% more energy efficient than CFL (compact fluorescent) bulbs. Second, the shape of CFL bulbs is not very aesthetic, not really visually appealing. Third, CFL bulbs contain mercury, which is toxic if released into the environment. Fourth, CFL bulbs have a short lifespan.

 

6. Will incandescent lamps be banned soon?

Answer:
Many customers believe that when LED lights are born and widely used, incandescent lights will be banned. Is that true?
The Ministry of Industry and Trade is studying a draft roadmap to limit and eventually ban the production and use of incandescent bulbs. LED lights will become the lighting technology of choice due to their lighting efficiency, long life, lowest cost and many other benefits for users. Currently, in Europe, the US, Japan, Australia, Canada and some other countries, the production and use of incandescent bulbs of 60W or more have been banned.

 

7. What environmental benefits do LED lights bring?

Answer:
In addition to the outstanding advantages of longevity, energy saving, … LED lights are also environmentally friendly lighting devices. So what are the benefits that lights bring to the environment?
The environment will benefit from the reduction of CO2 emissions for each kilowatt of energy saved. Each MW of electricity saved will reduce 1 ton of CO2 emissions. Too much CO2 emissions is an important reason for the partial destruction of the earth’s ozone layer and the beginning of global warming. In addition, an LED light has a lifespan equal to 50 conventional incandescent bulbs. This is a saving worth considering.

 

8. Are LED lights suitable for traditional lamp holders?

Answer:
Many families want to save money by using LED lights with traditional lamp holders, so are the lights suitable for use with traditional lamp holders?
The lights also use the same types of lamp holders as traditional bulbs:
– E27: means the socket diameter is 27 mm.
– E12: The diameter of this socket is 12 mm.
– GU10: The distance between the center of the lamp pins is 10 mm.
– MR16: also known as GU5.3, the distance between the pins is 5.3 mm.

9. What are the voltage and current requirements for LED lights?

Answer:
This is a question asked by many customers because they are worried that the voltage consumption of LED lights will be different from that of conventional lights. LED lights use AC voltage of 90-240V, 50-60Hz.

10. What color of light can LED lights emit?

Answer:
White light is measured on the color temperature scale in degrees Kelvin. LED light is usually divided into 3 types:
– Warm white: 2700-3500K. Similar to the color of incandescent light and the color of warm white light is often used indoors to create a warm atmosphere.
– Natural white: Usually 4000-6000K. Natural white light is often used for office, store, basement, or conference room lighting environments. Similar to the light of conventional compact fluorescent lamps.
– Cool white: Usually 6000-8000K. This is the color of white light that tends to be close to blue, often used in production environments and high brightness.
