General-purpose bulb
A parameter that describes the brightness of the lamp compared to a general purpose lamp (LON — a conventional incandescent bulb). Simply put, an analogue of LON is the power of an incandescent lamp, which is equal in brightness to the model in question. For example, a
75W LON analogue means that the lamp glows as brightly as a 75W incandescent lamp.
This parameter appeared for the convenience of evaluating and comparing different types of lamps in terms of brightness. Data on the luminous flux say little to the average user, and it makes no sense at all to evaluate the brightness by power — different types and even different models of lamps of the same type can differ markedly in efficiency. On the other hand, many users are accustomed to dealing with incandescent lamps, and comparison with such a lamp is familiar and understandable to them. In addition, the LON analogue allows you to compare different types of lamps, and it can also be very convenient when replacing incandescent lamps with more economical ones: for example, if 100-watt lamps were used in the chandelier, then the new lamps must have an LON analogue of
at least 100 W — otherwise they may be too dim.
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.
Google Home
The device supports the ability to integrate with the
Google Home smart home eco-system, as well as control from smartphones and tablets with the Android operating system. Using Google Home, you can easily and easily adjust the glow parameters: colour gradient, luminous flux, operating time, etc. Proprietary software allows you to create profiles with preset glow parameters — this can be a profile for workflow, relaxation, watching movies, etc. Distinctive A feature of the Google Home system is the presence of the Google Assistant voice assistant.
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.
Energy class
The energy efficiency class characterizes the economy of electricity consumption by a light bulb. Initially, classes were designated by simple Latin letters - from A (the most economical) to G (the most "gluttonous"). However, later improved classes A +, A ++ and A +++ appeared. The more "pluses", the more economical the light bulb in the end.
