Today it is difficult to say who first guessed to combine in one body two so important for any painstaking work of the device - a light source and a magnifying glass. But the result was so convenient that now without this hybrid manicure masters, cosmetologists, jewelers, radio operators and, of course, home-made embroiderers, do not think their work. About what kind of table lamps are lamps with illumination, and what should be paid attention to when choosing them, we'll talk today.
Desktop magnifying glass with backlight - the subtleties of choice
We will make a reservation at once that a table lamp-magnifier can not be called an inexpensive acquisition - the purchase of such a device can be quite tangible to the pocket. But if working with small objects takes you a considerable amount of time to shell out is still worth it. First, thanks to the lamp-magnifier, the load on the eyesight is significantly reduced, because you do not have to squint more, trying to make out the elements of the circuit or drawing pictures on the nails. Secondly, the work process goes much faster, because the hands are not occupied not by a magnifying glass, but by tools. Thirdly, the light falls at the right angle, lighting up all the elements well. When choosing a magnifying glass, you should pay attention to the following points:
- The degree of increase . The main working characteristic of any magnifier, as is known, is measured in diopters. But to think that the amount of diopters is equivalent to the degree of increase (like the zoom in digital technology) is not correct. For example, a magnifying glass in 8 diopters will increase not 8 times, but only 3, while its focal length will be 12.5 cm. Universal for any kind of work are desk magnifying lamps with illumination of 3-5 diopters.
- Lighting element . Classic desktop magnifying glasses are equipped with fluorescent lamps of 22 watts, but now there are many models with LED backlight. LED lamps consume less energy, which is especially important in light of the high cost of electricity and less heated during operation.
- Method of attachment . Magnifying lamp magnifiers can be mounted on a tripod or clamp. Mounting on a tripod allows you to easily move the magnifier from place to place, but it takes a lot more space. A lamp attached to a clamp can not be moved so easily, but it does not require a separate dedicated workstation.
