A Guide to Choosing Household LED Lights
A Guide to Choosing Household LED Lights

Energy-saving lamps have withdrawn from the stage of history.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

There are many LED lamps available on the market, and it can be difficult to tell the difference between the good ones and 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. First, let's talk about the driver. Normal household LED lights generally choose non-isolated drivers. This driver has average cost, high efficiency, and good reliability. Voltage fluctuations do not affect the lights' ability to work.

In order to compete on the market today, many companies use linear or resistor-capacitor power supplies in place of non-isolated supplies. These two power supplies have poor impact resistance. If a nearby thunderstorm causes a surge voltage, it will most likely cause damage. , can only work at the set voltage.

When purchasing, make sure you 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.

The chip inside will automatically adjust the duty cycle of the square wave to achieve stable output, so be sure to check the input voltage range when choosing.

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. It is difficult to see the quality of the light source with the naked eye, but generally it is not a problem after a few years of use. But you can look at the light on the package. It is better to select a color temperature that is below 6000k. Color temperatures of 3000k are preferred by Europeans and Americans. This is a slightly yellowish color, like the sun rising in the morning.

In our country, we like whiter ones. Generally, 6000k is like the sun at noon. It is brighter, but also whiter. 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.

Generally, the bulbs on the market are plastic-coated aluminum heat sinks, which means they feel like plastic to the touch. , there is actually a layer of aluminum inside.

The greater the power of the LED, the greater the heat. The heat sink usually has a power limit. So, when purchasing a lamp do not go overboard with power. Generally, the A60 should not exceed 10 watts. If it exceeds the lifespan, it will be discounted.

What to look for when choosing LED lights

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

Blue light is very harmful, especially for children under 8 years old. You can learn more about blue light by searching on Baidu.

Since the light from LEDs is a white light that is synthesized by combining three colors, red, yellow, and blue, blue light is unavoidable. There is also a lot of research on LED abroad to solve the problem of blue light. I hope we can all use LEDs without blue light in the future.

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

LEDs can be more efficient and save energy compared to energy-saving bulbs. The phosphors of energy-saving bulbs need to be fully preheated, especially when it is cold outside, before they reach the brightness required for the logo. LEDs aren't required.

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

The living room can use lights that convert between three color temperatures (neutral light, white light, yellow light)

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.

As far as household LED lights is concerned, yellow light is less harmful to the eyes, white light is more harmful to children's eyes, and blue light is only more harmful to children under 8 years old.

When choosing the right lighting fixture, you should consider:

  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. Choose the right size
  2. The style should match the overall decoration style of the home.

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:

Some customers say that the new Chinese-style and American-style lamps are so thin that they can be touch-ed with 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.

Nowadays, we buy lights not only for lighting, but also for decoration and light effect, to create a warm and comfortable home.

What is the best wattage to choose?

Generally, it is better to use 30-40 watt lamps for 10-15 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. The light strip is easier to install.


The light can be focused and the angle adjusted. It can be used to highlight certain points. Designers use spotlights as a way to emphasize the effect.


It is flat, and most of its function is as a lighting embellishment.

It is recommend-ed to use 3.5-watt downlights. The hole in the ceiling should be 7.5-8cm.

In general, it is recommended to use a downward light at a distance no less than 60 cm. Even 80 cm, or 1 meter is acceptable. If it is use-d for decoration, the number should not be too many.

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.

Mainly suitable for Nordic style decoration

All copper lamp

All-copper lamps cannot be made of copper. Copper is a relatively soft metal, so it can slip easily. Copper lamps must meet a 60% copper standard.

Decor is more often influenced by American and European styles.

corn light

Big corn brands don't do much because they have technical bottlenecks and it's difficult to achieve stable quality.

Its light-emitting surface is quite large. If you buy a chandelier with a lampshade, you can use this corn lamp. It is generally not recommend-ed to use corn.

Halogen lamp

Halogen lamps emit a yellowish light with a color temperature below 3000k. It is difficult to have a high color temperature, so it is not good for the eyes and the light environment is not very shaping.

filament bulb

They are actually imitations of previous tungsten filament bulbs, high-wattage filament 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. Placing a filament light bulb in a lamp may not look great.
