Choosing Household LED Lights Wisely

Energy-saving lamps have withdrawn from the stage of history. Almost all household lights are LEDs.

However, there are so many LED lamps on the market that it is difficult to distinguish the good from the bad. This short article teaches you how to choose high-quality LED lamps.

LED lamps actually consist of three parts: driver, light source board, and heat sink. Let’s start with the driver. Normal household LED lights generally choose non-isolated drivers. This driver is a good choice for its reliability, efficiency and cost. Voltage fluctuations do not affect the lights’ ability to work.

However, in order to compete with prices in the current market, many companies will use resistor-capacitor step-down or linear power supplies instead of non-isolated power supplies. Both of these power supplies are not very resistant to impact. It is likely that a nearby storm will cause a surge in voltage. Can only operate at a set voltage.

For example, 220V, as long as the voltage fluctuates, the light will also fluctuate, so when purchasing, be sure to check the input voltage range.

Resistance-capacitance and linear voltages are generally writt-en as 220-230v, and non-isolated power supplies are generally writt-en as 175-250v, and some can be 110 -250v voltage fluctuation has no effect on this lamp.

When choosing, be sure to consider the input voltage range.

Let’s now talk about the board that contains the LED light sources. At present, most of the LED light sources are weld-ed on the aluminum substrate. The quality of the LED light source is hard to judge with the naked eyes, but it’s not an issue after a few use years. You can check the light that is on the package. It is better to select a color temperature that is below 6000k. European and American countries like a color temperature of around 3000k, which is slightly yellowish like the sun just rising in the morning.

We prefer whiter shades in our country. Generally, 6000k is like the sun at noon. It is whiter, but more dazzling. It is best to choose a 4000k light source, which is more moderate. The light will appear blue if it is above 6000k. This is what is call-ed blue light hazard, so do not choose a color temperature above 6000k.

Let’s finish with the heat sink. Since the LED light source generates heat when it is working, if the heat is not dissipated in time, it will damage the LED, so a heat sink is needed.

Most bulbs are aluminum heat sinks that have been plastic-coated. They feel plasticky to the touch. , there is actually a layer of aluminum inside.

The greater the power of the LED, the greater the heat. Generally, the heat sink has a maximum power limit, so when buying a lamp, do not be greedy for high power. Generally, the A60 should not exceed 10 watts. It will be discounted if it is over the lifespan.

How to choose LED lights

Blue light is the most important factor to consider when choosing LED lights.

The blue light can be very harmful to children, especially those under the age of eight. (You can search on Baidu to learn about the dangers of blue light)

The light of LED is white light synthesiz-ed from three colors: red, yellow and blue, so the blue light in it is still unavoidable so far. There is also a lot of research on LED abroad to solve the problem of blue light. I hope that in the near future we will all be able to use LED lights without blue light.

Online, it is uploaded that you can judge the LED strobe using your mobile phone. This is not a very accurate standard, and you have to make a comprehensive judgment from all aspects of light color.

Energy-saving lamps vs LDE lamps

Compared with energy-saving lamps, LEDs are more energy-saving and can make full use of light efficiency. Especially when the weather is cold, the phosphors in energy-saving lamps need to be fully preheat-ed before they can reach the brightness of the logo. LEDs are not requir-ed.

For children’s bedrooms, it is recommended to use neutral lighting with a 4000K color temperature.

You can choose between neutral light, white or yellow light for the living room.

In the living room, ceiling fan lights should not be used. On the one hand, the light intensity is not sufficient, so they can be use-d in the dining room.

In terms of household LED lighting, yellow light has less impact on the eyes. White light has more effect, while blue light only affects children younger than 8 years.

How to choose the right lighting fixtures should pay attention to:

  1. The LED light will appear blueish if there is too much light. This is bad. White light is normal.

American-style lampshades are relatively thick, so it is recommend-ed to use white light bulbs.

  1. The right size
  2. Style should be in harmony with the decor of the house.

Lamps play the finishing touch. We must not only choose the style, but also pay attention to the light color. For simple Nordic style, choose simpler lamps. European and American chandeliers will work best.

  1. When choosing, pay attention to the light color and quality.

Popularize the issue of hanging lamp height:

Customers have said that the new Chinese and American style lamps are so thin, they can be touched with their hands. uncomfortable!

Answer: Leaving aside the aisle, a good golden ratio effect is the distance between floor in the living room and lamp. In a restaurant, this distance is usually between 0.85 m and 0.95 m.

We buy lights today not just for illumination, but for their decorative and illuminating effects, in order to create a comfortable and warm home.

How much wattage should you choose?

In general, 30-40 watts of light is best for 15 square meters.

Generally speaking, if the living room is 15-20 square meters, it is better to use 70-75 watt lights. For 20-25 square meters, it is better to use 80-90 watt lights. For more than 25 square meters, it is better to use LED lights of 105 watts.

Our common lamps:

light strip

Nowadays, most of the flexible light strips are use-d, but now LED has come out with T5, which is brighter and more stable than light strips.

It is easy to replace a broken section of the middle because it is connected one-by-one. But the light strip is more convenient to install.


You can adjust the angle and focus the light. It can be used to highlight certain points. Designers use spotlights as a way to emphasize the effect.


It’s flat and its main function is to enhance lighting.

It is recommend-ed to use 3.5-watt downlights. If the hole is open-ed in the ceiling, it should be between 7.5-8cm.

It is generally recommend-ed to use a downlight at a distance of no less than 60 centimeters. Even 80 cm, or 1 meter is acceptable. The number of pieces should be kept to a minimum if it’s used for decoration.

molecular lamp

The material used for the LED household lights and lamp body as well as its workmanship are the main factors that determine the choice of molecular lamps.

Suitable for Nordic style decor

All copper lamp

All-copper lamps cannot be made of copper. Copper is a relatively soft metal, so it can slip easily. The national standard is that the copper content is 60%, which can be call-ed a full copper lamp.

American and European styles are more commonly use-d in decoration.

corn light

The big corn brands aren’t doing much because of technical bottlenecks, and it is difficult to maintain quality.

Its light-emitting surface is quite large. If you buy a chandelier with a lampshade, you can use this corn lamp. Corn is not recommended.

Halogen lamp

The light of halogen lamps is yellowish, and its color temperature is below 3000k. The color temperature is too high and is bad for your eyes.

filament bulb

These are imitations of the old tungsten filament lamps, which were high-wattage bulbs. They are not made by many domestic factories. The majority of filament bulbs today have a color temp of 2700. This is used to create an atmosphere. It may be a little worse for lighting.

This kind of household LED lights bulb looks better when used with most Nordic and American lamps, if it is European or simple. Putting a filament bulb may not necessarily look good
