Consumption
The power consumed by the light bulb during normal operation. The lower this indicator, the more economical the model and the cheaper it will cost to operate. In traditional incandescent lamps, the brightness of the glow also depended on the power, however, different types of lamps are presented on the modern market, with different efficiencies. Therefore, it is possible to uniquely link the power consumption and brightness only in lamps of the same type (see above), and to compare different types of models, you need to use the LON analogue (see below).
Luminous flux (brightness)
The conditional "amount of light" produced by a light bulb in normal mode. The higher the luminous flux, the brighter the light and the more clearly the illuminated scene will be visible. Note that lumen values are used primarily for special purposes; in everyday life, the estimation of brightness by the analogue of LON is more popular (see above), and here the ratio is as follows:
— 40 W analogue LON corresponds to a brightness of 370 lm;
— 60 W — 550 lm;
— 75 W — 800 lm;
— 100 W — 1200 lm;
— 150 W — 1900 lm;
— 200 W — 2700 lm.
Note that the principle "the more the better" in the case of the brightness of light bulbs is not always applicable. And the point here is not only energy consumption: too bright light is harmful to the eyes, leads to rapid fatigue and psychological discomfort.
Apple HomeKit
Apple HomeKit -enabled light bulbs are compatible with software used in Apple's smart home eco-system. First of all, thanks to this, the operation of the light source can be controlled from an iPhone, iPad / iPod or even a MacBook. The HomeKit application opens up fairly wide possibilities for setting up lighting modes, allowing the user to change the colour shade and intensity of the light bulb, programme its operating time, etc.
Voice assistants
The operation of
light bulbs with voice assistant support can be controlled using voice commands. The most widely used voice assistants are Apple Siri, Microsoft Cortana, Amazon Alexa and Google Assistant. Most often, the voice assistant interacts with the Smart bulb through a special application. This can be Google Home, Apple HomeKit, etc. That is, the user sends commands to the software on his portable computer/mobile device.
