The data are derived from national energy efficiency standards, authoritative laboratory measurements, formal brand open parameters, objective neutral, non-exaggerous and non-false information, and only writers who use lighting and selection references to actively pursue and comply with platform norms。
Many families have had a visual feeling in recent years:
Incandescent lamps and energy-saving lamps were replaced by households in the same year, in the interest of electricity, durable and long-lived leds. So far, many people have found that the more dark the light, the less expensive the electricity, the higher the frequency。
Some say that the led light has gone down the altar and that the power-saving advantage no longer exists。
What's the real story? I use the most recent measurements of march 2026 to make it clear in plain language that it is not exaggerated, that it is untitled, that it does not create anxiety, that it is understandable and useful for every ordinary family。
First, let's get this straight: led is still the most power-efficient, which is the law of physics
See first the mandatory national standards and the measured data, all of which are verifiable and verifiable:
• incandescent light: 10-15 luminescence/wat, 90 per cent of electrical energy turned to heat, and only 10 per cent to heat light
• general energy-saving lamps: 50-60 lumber/wat, half of electricity wasted
• compliance led lamps: 95-160 luminescence/wat, with more than 80 per cent electrical luminescence
Based on the most common household usage:
10 wld = 40 ww incandescent light
Five hours a day for lights, $0. 6/degree for electricity
• monthly electricity bill for incandescent lamps: approximately $3. 6
• monthly electricity bill for led lamps: approximately $0. 9
One lamp saves 30 pieces of electricity a year, the entire house is replaced, and it is normal to save a bag of rice flour a year。
In terms of energy efficiency, leds continue to be one of the most power-saving options available for civil lighting. This objective conclusion is also the basis for the state's vigorous promotion and elimination of old lamps。
It was felt that the problem was not the quality of the led itself, but the quality of the product, the selection and the usage of habits。
Ii. Why do many people think that leds use more dark and more electricity
It's not led. It's three common problems
1. Severe light decay: the more dark it is used, the greater it is, the greater it is
Regularly qualified leds, with 5,000 hours of brightness retained for 90 per cent of thallium, with little change over three years。
Low-priced low-quality leds, heat spreads, chip differentials, 30 per cent brightness in six months, half year。
When the lights go dark, you'll be unconscious longer, you'll have more lights, and you'll get electricity。
2. Driving power is too poor to bring down the lamp life
Led beads can have a life of 50,000 hours, but cheap power can only be used for 1-2 years。
A bad driver does not light the light directly; the drive is unstable and there are flashes and increased electricity consumption。
A lot of people spit “short lives”, not beads, but a few cents。
3. Defunct power, not bright enough to count
The nominal 10 watts were actually only 7 watts; for the sake of brightness, the current could only be lifted。
The result is more power-consuming, hotter, and worse。
Looking at cheap, it's actually a “snatch-down plus hidden waste”。
Brief summary:
It's not led without power, it's poor quality led wasting power。
Three, 2026. What about leds? I'll buy it at 5:00
I translate professional standards into big words, and ordinary people just buy them:
1. Recognition of primary energy efficiency, which is the national threshold
China's energy efficiency marker on the lights gives priority to the first level of energy efficiency。
National standard requirements: level i energy efficiency photo-efficiency 95lm/w, power conservation。
2. Look at light failure parameters and do not just listen to merchants
The formal product will be marked as: 5,000 hours of light maintenance at 90 per cent。
Without that standard, it takes six months to get darker。
3. Color index ra≥80, more comfortable household
In the living room, bedroom, library, ra>80, reading and writing。
The colour is real, the light is soft, it's not tired。
4. Must be flashless, low blue light
Use a mobile camera to look at the light, no scrolling black strip, no flash。
Children's rooms, desks, priority for full spectrum leds, closer to natural light。
5. Don't be greedy. It's good enough
• kitchen, balcony: 5-10 w
• bedroom: 12-18 watts
• living room: 24-36 w
The greater the number of watts, the greater the power consumption, the most suitable brightness。
With these five points, led lamps can be fully realized by saving electricity, durability and eye protection。
Iv. Also led. Why is the price multiple
A lot of people don't get it: leds, why 3 dollars, 30 dollars
The core is in three places:
Lightball chips: brand chips are stable, declining, and have a long life
2. Drivers: good drive stability, power saving, durable
Diffusion material: aluminium base plate is well dispersed, light is difficult to dark and difficult bad
(a) three-dollar lamps that are lighted but do not save electricity, do not last, do not protect the eyes
A 30-dollar compliance light, a little more expensive at a time, always saving electricity, hearts and money。
For ordinary families, it is cost-effective to save electricity, to replace it less and not to hurt them。
V. Rational view: led did not walk down the altar, but returned to reason
When any product becomes widely available, there are three stages:
1. Initial period: new and effective to the altar
2. Medium-term: low-quality product influx, mixed experience and declining reputation
3. Age of maturity: good standards, good quality product ownership, return to practicality
Today's led, in maturity。
It is not a panacea, but it remains the best energy-saving lighting programme for families。
Its strength has always been:
• more than 80 per cent less electricity than incandescent lamps
• more than 40 per cent power savings compared to energy-efficient lamps
• non-mercury, environmentally safe
• switches light without delay
• multiform and fit for various improvements
As long as the product is selected for compliance, it remains the best solution for household lighting。
Vi. Practical recommendations for the general family
1. Old houses also have incandescent lamps, old energy-efficient lamps, replaced by an energy efficiency led 1 as soon as possible
2. Children's rooms, desks, priority for full spectrum, non-frequency flash, high-visibility products
3. Lights are regularly polished, dust is shielded, heat is affected and electricity is indirectly charged
Don't buy three products at a very low price
The bad lights don't work. The lights don't only cost electricity, they hurt their eyes
Power saving is not a trick; it is living
The choice of a pair of lamps will save electricity and protect the eyesight of the family。
Summary
The led lamp did not go down the altar and the power-saving advantage remained。
Most of them are poor products, not technologies。
Today, 2026, compliance with leds remains the most cost-effective and environmentally friendly domestic lighting option。
A lamp is chosen to save electricity, light and long-term use。
The real advantages of leds can only be put into practice if they are not blind, if they are not cheap, if they are rationally selected and used in science。
Topical discussion
Is your house using led lights now? Have you ever experienced any darker, more frequent damage
When you choose to buy lamps, do you value power savings, eye protection or price
