TESLAbikář or how to choose the right LED bulb
6. part of the beam angle of LED bulbs
It is the angle at which the light shines into the space and is thus sufficiently intense. Classical bulbs had a fixed angle - simply 360°. But modern LED bulbs from TESLA lighting can be manufactured with different beam angles (25°, 38°, 100°, 180°, 220° and 360°).
Some lights are fitted with a cover/diffuser that primarily protects the light source from damage and other external influences. It also helps to diffuse the light that is emitted. If the diffuser is transparent, then it lets the light through in its full colour and intensity. A milky diffuser, on the other hand, attenuates and softens the transmitted light and, because of its colouring, does not transmit direct light.
The next part will be dedicated to the CRI or colour rendering index of LED bulbs, which are in the range of TESLA lighting.
