TESLAbikář Part 5 Chromaticity temperature or colour temperature of LED bulbs

TESLAbikář or how to choose the right LED bulb Part 5 Chromaticity temperature or colour temperature of LED bulbs We know the sockets, we know the shapes, we know the wattage, we know the luminous intensity. Another selectable variable of LED bulbs is the colour - the colour temperature, given in Kelvin (K), because we encounter different shades of light with different sources. IS WHITE REALLY JUST WHITE? If we forget [...]

TESLAbikář 4. part luminous flux or luminous intensity of LED bulbs

TESLAbikář or how to choose the right LED bulb 4. part luminous flux or luminous intensity of LED bulbs The luminous intensity of conventional bulbs was determined by their wattage (W). Today, with modern LED technology, however, we cannot tell how much an LED bulb will shine by its wattage (W). Because different light sources have different luminous intensities at the same wattage. What is LUMEN? [...]

TESLAbikář 3. part power consumption of LED bulbs

TESLAbikář or how to choose the right LED bulb Part 3 LED bulb wattage The wattage tells us how much electricity the LED bulb consumes, i.e. how much it will cost us to light up. It gives us the instantaneous power consumption of an LED bulb in units of watts (W). We express the hour of operation of an LED bulb in watt-hours (Wh) or kilowatt-hours (kWh). Let's show this with the example of [...]

For greater clarity and in view of the constant technological developments, the European Union has announced an update of the energy labels for most appliances on 1 March 2021. The [...]

High colour rendering index bulbs

High Colour Rendering Index bulbs The colour rendering index (CRI or Ra for short) determines the fidelity of colour perception to the human eye. It evaluates the ability of a bulb or luminaire to display colours compared to normal daylight. The index is given in values from 0 to 100. To give you an idea: At a value of 0, no colour is discernible. On the contrary, [...]
