Comparison Xiaomi Yeelight LED Vision Desk Lamp V1 Clamp vs Xiaomi Mijia LED Lamp Pro

The maximum power of the light source allowed for a given lamp.

This parameter has different meanings depending on the light source (see the corresponding paragraph). It is most critical for models with sockets for replaceable light bulbs: the power of the light bulbs used should not exceed the maximum power of the lamp. Otherwise, it will overheat, and the consequences can be very unpleasant - even a fire. In this case, for models with several cartridges, the total power of all installed light sources is indicated. In order to determine the maximum permissible power of an individual light bulb, you need to divide the total limitation by the number of sockets. For example, in a model with 7 “seats” and a limit of 140 W, you can install bulbs of no more than 140/7 = 20 W.

It is also worth recalling that the actual brightness of the light bulb will depend not only on its power, but also on its type. Thus, at the same brightness, “energy-saving” fluorescent lamps have a power 3 to 5 times less than incandescent lamps, and LED light sources - 10 times less. Thus, low permissible power does not interfere with achieving high brightness.

As for table lamps with built-in LEDs, the maximum power for them corresponds to the actual power of the LED unit. You can roughly estimate the capabilities of such a lamp using the above formula - the brightness of the LED corresponds to the brightness of an incandescent lamp with 10 times more power. For example..., if you previously made do with a 60-watt light bulb, an 8-watt LED lamp will most likely be enough for you.

Wattage also determines the energy consumption of the lamp. However, it is not particularly high in table lamps, and in models with a replaceable socket, it also depends not on the maximum power of the lamp itself, but on the characteristics of the actually installed light bulbs.

Luminous flux provided by a lamp. This parameter is indicated only for models using built-in LED modules (see “Light source”) - in lamps with a socket, it will depend on the light bulbs used.

Luminous flux is essentially the brightness of the lamp. The brightness itself in lumens tells little to the average user, a non-specialist; however, there are tables that allow you to compare the luminous flux of a lamp with a particular light source of standard brightness. For example, a 40 W incandescent lamp produces about 415 lm, a 60 W lamp produces 710 lm, and a 100 W lamp produces 1340 lm. More detailed tables for comparison can be found in special sources.

Speaking of brightness, it is also worth noting that it should not be too low or too high: both create discomfort, increase fatigue and can lead to eye problems. Reference sources provide recommendations on optimal brightness for different tasks. However, this point can be determined for yourself experimentally. And if in doubt, you can purchase a lamp with adjustable brightness (see “Functions and capabilities”).

The colour temperature of the light emitted by the lamp. It is indicated only for models with built-in LED (see "Light source"), since bulbs with different characteristics can be installed in the socket. In luminaires with colour temperature control(see "Features"), the minimum value is usually taken into account.

This parameter directly determines the hue of the visible colour. At the same time, its physical meaning is such that as the colour temperature rises, this shade becomes more “cold”, shifts from yellow to blue. Here are some examples of colour temperature, for clarity:

— 1500 – 2000 K — candle flame;
— 2800 K — 100 W incandescent lamp ( warm light);
— 4000 K — a fluorescent lamp of daylight white light(such light can already be perceived as cold);
— 5000 K — the light of the midday sun;
— 5500 K — a shade from white clouds at noon;
And so on, thickening to blue cold shades.

Note that the choice for this parameter depends not only on personal preferences and design considerations, but also on the general purpose of the lamp. So, a high colour temperature (from 5000 K) is considered optimal for reading, an average colour temperature (about 4000 – 5000 K) is comfortable for mathematical calculations, working with documents and other tasks that require concent...ration, and soft warm light up to 4000 K is good for relaxing and creating atmosphere of comfort.

To control from a smartphone(or tablet) you need to install a special application on the gadget. This feature not only makes it possible to control the lamp from a distance: most models with this function are advanced “smart” lamps with various additional settings, such as adjusting the brightness and color of the glow. Controlling the operation of such lamps through a mobile application is much more convenient than using buttons and other classic controls. However, the specific functionality of models compatible with smartphones may be different; it should be clarified separately. The device can connect via Wi-Fi or Bluetooth (depending on the model).

Compatibility of the light bulb [table lamp] with proprietary Xiaomi Smart Home software, thanks to which the device can be integrated into the Xiaomi smart home ecosystem. This opens up the possibility of remote lighting control, including creating a schedule for the operation of a light bulb [lamp] and automating its actions, remotely changing the color gradient and luminous flux, voice control, etc. In addition, the light source can be closely interconnected with other Xiaomi Smart Home devices to create comprehensive control scenarios for the entire smart home.

Lamps with voice assistant support can be controlled using voice commands. The most widely used voice assistants are Apple Siri, Amazon Alexa and Google Assistant. Most often, the voice assistant interacts with a Smart device through a special application. This could be Google Home, Apple HomeKit, etc. That is, the customer issues commands to the software on his portable computer/mobile device.

The type of fastening provided in the design or delivery of the table lamp.

In this case, fastening means a device for rigidly fixing the lamp on the table. Many of these lamps also cost a stand, however, in some cases, you can’t do without fastening — for example, if there is an increased risk of hitting and dropping the lamp, or if it is long and would be unstable on the stand. At the same time, there are models equipped with both a stand and a mount, at the user's choice.

Types of fasteners can be as follows:

— Clip. The latch in the form of a large clothespin — from two halves, attracted to each other by a spring. Clips are less reliable than clamps, which is why they are used only among compact low-power models. However, this moment also gives its advantage: such a lamp can be fixed even on a thin and not very strong surface, such as a sheet of hardboard or even thick cardboard, while a clamp requires a rather thick and rigid support. In addition, the clip opens and closes almost instantly, which makes it easy to move such a lamp from place to place.

— Clamp. Fastening based on a screw mechanism: one sponge of such a device is stationary, and the second can move back and forth when the screw rotates. When twisting the clamp, the sponges compress the countertop, fixing the lamp on it. Clamps are bulkier and "slower" than clip-on clips and take longer t...o open and close. In addition, when tightening the screw, you should be careful not to overtighten it and not damage the countertop. On the other hand, a properly installed screw clamp provides a very tight and secure mount, suitable for even the largest and most unstable table lamps.
