Luminous flux of lighting lamps

Every year, from the screens of TVs and other media, it is increasingly and more clearly asserted that the reserves of minerals are running out, so the cost of energy carriers is constantly increasing and it's time to think about saving. This also applies to electric energy, since its production is interconnected with other spheres (oil products for lubrication of bearings of generators, smelting by metal plants for wires, etc.). To reduce the cost of paying bills , it is recommended that you do not forget to turn off the lights in those rooms where it is not necessary, then replace the light sources with more progressive ones, and at the end - use the technology "Smart House". Turn off the light, everyone has learned to computerize the dwelling of the average city dweller for the time being, but to study what is the light flux and replace the lamps - just the time, the more fluorescent and LED solutions can already be purchased at every market counter, not to mention shops.

Few people know that choosing a replacement for the usual incandescent lamps, it is necessary to pay attention not only to the electric power consumed by the new models and the color temperature, but also to the emitted light flux. To forget about this is highly discouraged, since there may be a situation when the boasted model of a new lamp in this parameter is inferior to the old one. Its luminous flux may be less than that of faith and truth. Such a replacement, although it will save electricity, is unlikely to bring joy. What is the light flux, as applied to the lamps of illumination? This is the amount of radiant energy that makes up the entire spectrum of radiation that is captured by the human eye and is defined as "light." A special spherical logger is used for the measurement.

The light flux of an incandescent lamp, which for many years was the standard source of illumination, has long been measured and defined in GOSTs. Released in 1999 for popular 60W lamps, it indicates a minimum luminous flux of at least 620 lumens (lumens), and varieties with increased flow should produce more than 710 lumens. Moreover, after a month of continuous operation, the decrease in the luminous flux should not fall below 85% of the nominal value. According to this parameter, incandescent lamps have no equal. Is this a lot or a little - 600 lumens?

To answer this question it is necessary to familiarize yourself with the technical characteristics of their modern analogues, based on LEDs. The light flux of LED lamps indicates on the packaging is not all manufacturers. It is understandable: the power consumption is always written in large letters (it is really small), and the color temperature and, moreover, the luminous flux are either not mentioned at all, or written in small letters.

For example, consider an incandescent lamp with a power of 100 W and an equivalent LED model. Everyone knows that LEDs have a relatively low power, but at the same time they can efficiently give light energy in terms of each watt. If the incandescent lamp (100 W), this parameter is 10 lm / W, then the LED is as much as 61 lm / W. Someone has already calculated that the light flux of the 11 W LED lamp is 617 lumens, and that of 100 watts of incandescence is 1000 lm. Outcome: at present, to replace the example of the incandescent lamp, you will need to purchase a 15W LED model.

Every day there are new varieties of lamps that can more effectively give off light energy. Using advanced diodes and control circuits allows to increase the overall efficiency. The main thing when buying - read the manufacturer's specifications. And not only what is written in large letters on the front side, but also all other specified parameters.
