Hi, habrachelovek! In this article I want to talk about how to properly screw the light bulb.
This “article” is nothing more than humor, so please take it as humor =) 
Many may argue, they say it is elementary, but here, like any other business, there are also secrets!
1) Choosing a light bulb. It’s a very important part of the task, because what kind of light bulb you choose depends on your future fate! But before you choose a new light bulb, you need to unscrew the old one (for how to do this, see the next article) and look at its type and power, which you need to remember, and it is better to write it down on a piece of paper (preferably in a box). If you are satisfied with the old lamp, then the choice is much easier, you just need to choose the optimal price / quality model. If you are not satisfied with the previous lamp (its brightness, color, shape) or you are using an image intensifier for the first time, then I recommend choosing the appropriate model in our online store, you can also follow the news in the world of light bulbs on our twitter!
2) About screwing the lamp narration So, at the moment you have already chosen and purchased the lamp. A natural question arises: what to do next? The answer is ingeniously simple, you need to screw a light bulb into a cartridge! If you chose the right light bulb, then it will not be more difficult, you just need to gently insert the light bulb into the cartridge and slightly pressing it turn clockwise. If the light bulb does not fit the cartridge, then our Twitter editorial recommends changing it to an analog with a suitable base. Attention, adhere to safety and carefully read the instructions and datasheets before installing the necessary lamp. Well, that's all, I hope this lesson was useful to you. If you have any questions, ask in the comments, do not hesitate! And do not forget to follow the news on our twitter, good luck!
