100 yuan is the desk lamp to 200 yuan useful? What do you recommend?

It is the following three goods, from left to right.

Mijia LED intelligent desk lamp 1S, 179 yuan.

Besi rechargeable plug-in folding desk lamp, 149 yuan.

Panasonic rechargeable desk lamp, 69 yuan.

Next, I will talk about their respective advantages and disadvantages.

1, all three designs are folded, and the folding angle can reach 180 degrees, almost flush with the vertical pole, which is really soaring.

Mijia 1S

Design is Xiaomi's consistent strength. The design of this 1S is also excellent, simple and atmospheric, and it has won several design awards.

The shortcomings are also obvious. White plastic material is easy to get dirty and needs to be taken care of frequently. Lazy people should be careful, otherwise it will be a small fingerprint punch+vacuum cleaner.

Vazeuz

The folding design is also adopted, and the lighting angle can be contracted freely.

Compared with other Bess products, there are always surprises in small details, and the appearance material of gray aluminum alloy is one of them.

Available in grey and white. I chose gray. I couldn't see it when it fell. More resistant to dirt.

And gray is easier to coordinate with the color of furniture, so it is not so presumptuous. Gray is more suitable for boys than white.

Matsushita Co., Ltd.

Panasonic's overall design of this desk lamp is not as good as the first two models, and its style is relatively simple.

There are two official colors: white and black. I chose a relatively calm black. Later, I found that black is easier to get dirty, and I can see it clearly with a little dust.

2, occupying space The space occupied by the three desk lamps is not large, but there are still relative differences.

Mijia 1S

The space occupied is about the size of a small plate, not too big, but it can't be said to be small.

Vazeuz

Besi is the most space-saving of these lamps. The base is only as big as a cup, and it is very stable (because there is a 2200mA battery in it, the base is relatively heavy).

Comparison of land occupation of three bases:

Matsushita Co., Ltd.

Panasonic's base is relatively large, occupying a little space, but it is acceptable.

3. Lighting standard Mijia 1S

Mijia 1S adopts the new national standard A-level illumination, and the illumination is above 250LX;

Ra90 has high color rendering index, better color reproduction and brighter color.

Vazeuz

The maximum illumination is 500LUX, and Ra95 has a high color rendering index, which is better than Mijia 1S in maximum illumination and color reproduction.

Matsushita Co., Ltd.

The official did not provide illumination data, only one luminous flux was 200lm.

The color rendering index Ra80 is not as good as the first two paragraphs. If it's not painting, it should be enough.

4. Dimming Mijia 1S

Color temperature and brightness can be continuously adjusted (stepless adjustment means continuous adjustment without segmentation).

Color temperature supports from 2700K warm yellow light to 4000K warm white light and 5000K cold white light.

Vazeuz

Three-level dimming, the highest illumination is 500LUX.

Color temperature supports from 3000K warm yellow light to 4500 K warm white light to 6000 K cold white light.

In terms of dimming, Bess has a bright spot: it supports intelligent automatic dimming.

Beth's folding desk lamp has a built-in photosensitive element, which can automatically identify the ambient light, intelligently adjust the illumination of the desk lamp according to the ambient brightness, and avoid visual fatigue caused by too dark light or glare caused by too bright light. There is an automatic dimming switch at the bottom to turn this function on/off.

Matsushita Co., Ltd.

Only 4000K color temperature.

Three-level brightness is adjustable, nightlight brightness 10%, atmosphere brightness 40%, reading brightness 100%.

5. Eye protection Mijia 1S

RG0 class, no blue light hazard.

Vazeuz

RG0 class, no stroboscopic, no blue light hazard.

Matsushita Co., Ltd.

The official did not mention the level of eye protection. No strobe was found in the mobile phone test.

6. Endurance Mijia 1S

Mijia 1S has no battery, so it can only be plugged in.

This is the biggest inconvenience of this desk lamp. It is unfriendly to students who can turn off the lights and power, and its mobility is worse than the other two models.

The socket is a special small round DC port, which can't be used with the charging cable of the mobile phone.

Power: 9W

Vazeuz

This desk lamp comes with its own battery, and the maximum brightness can be used for 3 hours after full charge, and the low brightness can be used for 13 hours. Movable, suitable for college students to put on desks or beds, and even take them outdoors, which is very convenient.

The charging port is a Type-C port, which can be used with the charging cable of the mobile phone, which is absolutely beneficial and avoids the accumulation of too many data cables on the desktop.

Power: 5W

Matsushita Co., Ltd.

Movable, according to my actual use effect, the highest brightness can be used for about three hours.

The power display has four grids, which can judge the remaining power more intuitively.

The power cord is an old m-USB port, which is not very friendly for new mobile phone users with Type-C port, so a special cord is needed.

Power: 4.5W

7. Intelligent function Mijia 1S

Xiaomi 1S has intelligent function, which can be intelligently controlled by Mijia APP or Apple HomeKit.

The most convenient feature of this function is that sometimes people have gone to bed, but forget to turn off the lights. Just shout "Little Love, turn off the lights" and it will be very convenient.

Smart mode has four reading modes, including reading, computer use, children's mode and concentration mode. Because I am too lazy to toss, I have basically never used it. ...

In focus mode, you can customize working hours and rest time. At that time, the light will turn into a warm light breathing state ... I just threw it away after the test, because I want to finish it continuously as soon as I get up, and I don't want to come back after a break ... This function is useless to me.

Bass and Panasonic

None of them have intelligent functions.

8. The price of Mijia is 1s- 179 yuan.

Beisi-149 yuan

Panasonic -69 yuan

It is concluded that Xiaomi 1S has stepless dimming, complete functions and intelligent control function.

The disadvantage is that it can only be plugged in and has poor mobility, so it is not suitable for dormitory with lights out and power off at fixed points.

Bess folding desk lamp is three-level dimming, which can automatically adjust the illumination according to the ambient brightness; The gray design is more resistant to dirt, occupies a smaller area, can be used unplugged, and is very suitable for student dormitories.

Type-C port can share a power plug with mobile phone, which is very practical.

The disadvantage is that there is no intelligent function.

Panasonic is a three-level dimming, and its color rendering index is average. You can only plug it in. Its advantage is that it is cheap and suitable for students who don't have high requirements for color rendering and intelligence.

I watched a variety show before, and compared the stroboscopic frequency of 30-600 yuan table lamps on the market, the lowest stroboscopic frequency is the domestic old-fashioned table lamps, with more than 30 pieces.

Let's talk about the harm caused by stroboscopic:

The main hazards of stroboscopic:

1. Causes headache and eye fatigue.

Many migraine sufferers are very sensitive to light, and if the light is bright and flashing, it is more likely to cause migraine. Slow flicker is usually more likely to cause migraine than fast flicker.

Developing autism

Children with autism are particularly sensitive to environmental changes, and stroboscopic lighting increases the recurrence of this behavior.

3. Trigger photosensitive epilepsy

Under the modulation of visible light in the range of 3-70HZ, people who are sensitive to light will have seizures even if they are exposed for a short time, which will probably affect 1/4000 people aged 5-24 years. Usually, 75% people will be sensitive to light for life from around puberty.

Divert attention

People's visual field is sensitive to stroboscopic, such as flashing signal lights or rapid modulation generated by automobile taillights, which will attract drivers to stare all the time. Looking away ahead of time may cause danger to drivers or people and things on the road. The combination of stroboscopic light source and running opportunity produces opening and closing effect, which causes harm to people, resulting in obviously different moving and stopping speeds.

NVC is very good! My children are using it themselves.
