Household LED lights a few even ask!

1. How many decades is the life span of LED lights at home?

The theoretical life span of LED lights is 100,000 hours, and if used normally, it is not a problem to use a few decades. But in actual use, it always breaks down in three to five years.

There are two reasons for this.

The first is that the quality of the luminous body is not up to scratch, and the packaging of LED lights for home use needs to be absolutely dust-free. Unfortunately not many brands are able to do this - a single grain of dust on the lamp beads will cause them to overload and thus burn out.

Secondly many lights break down, in fact, it is not the luminous body that is broken, but the starter is broken. The life of the luminous body has 100,000 hours, but the life of the starter is not so long.

2. the yellow light of household LED lights is darker than the white light?

Many people think that yellow light is darker than white light, which is actually a misconception. The reason why people think that yellow light is dark is because candlelight and incandescent light are emitted as yellow light, while the brightness of these two light sources is not enough.

In other words, brightness and darkness are only related to the brightness of the lamp and not to the colour temperature.

There are also special cases where it is clear that the luminaire is very bright, even a little blinding, and yet you still feel that you cannot see anything. This is not a problem with the eyes, but the colour rendering index of the luminaire is not enough. The colour rendering index of LED lamps for home use should be at least 90.

3. home LED lights than other lights more energy-efficient?

This statement is not entirely correct, we should replace the word "power saving" with "energy saving": LED lights are more energy efficient than other lamps. In other words, they are more efficient. They produce the same brightness, and LED lights are more energy efficient.

Many users have reported that the lights in their homes are very power-hungry, with a monthly electricity bill of nearly 100 yuan just to turn on the lights. This is all normal - because your standard of living has improved.

In the past, when you used incandescent lamps, you just had a light at night. Now the night, every day lights. 60W LED lights, power consumption and 60W incandescent lamps the same - but the former can make the room bright as day, the latter can only make the room less dim.

4. Are coloured household LED lights dimmer?

LED lights can only emit the colours in the spectrum, yellow, white and at most a little red or a little blue.

You want LED lights to emit pink, green and other colourful light, you need a coloured cover over the lamp beads. This cover interferes with the spread of light and so makes the coloured lamps appear darker.

A coloured lamp of the same power is less bright compared to a white lamp. If you want to increase the brightness, you have to increase the power of the luminaire (the power consumption will also increase).

5. Why are some domestic LED luminaires harsh on the eyes?

All harsh lamps have a common feature: they are harsh when close to the lamp and dim when far away from it. This is because the angle of illumination of the luminaire is relatively small, and all the brightness is concentrated together.

Luminaires with small angles are used in two ways: firstly, in narrow spaces, such as corridors, and secondly, for decorative lighting, which is specifically designed to project a spot of light on the wall.

Lamps used for lighting and illumination are generally not chosen for these small-angle lamps. Feeling harsh, you may have chosen the wrong one.
