FAQ - Frequently Asked Questions
LED bulbs have a different design than conventional bulbs. For their trouble-free operation, it is recommended to use a dedicated power supply. Older transformer sources are generally not suitable for powering these bulbs. Power supplies for LEDs are relatively affordable and both their efficiency and size also play clearly in favour of replacement. They work with a DC voltage of 12V, the power needs to be calculated by the sum of all the bulbs that will be connected to this source.
LED light sources are based primarily on emitting white light, for which a team of scientists won the 2014 Nobel Prize in Physics. The color is affected in LED light sources by the amount of yellow phosphor that is placed on the LED emitter. According to the colour of the light (given as a value in Kelvin), the different components of the emission change. As an example, below you will find a picture of the emission spectrum for our 4 W bulb in 3000 K.
Below is the emission spectrum from the LED tube with 5500 K light colour.
Please note the difference in the blue part of the spectrum, that is the blue light you mention.
LED light sources in the colour range 2700 K - 3000 K are therefore also suitable for use in bedrooms. In addition, you do not have to worry about your children getting burned by the bulbs or being at risk of breaking the bulb, as LED sources do not contain any harmful substances.

Today, the entire TESLA Lighting product portfolio is manufactured under strict systematic control in pre-screened factories in Portugal and China, just as we show on our website tesla-lighting.cz. The development of technology and design takes place in the Czech Republic at the original TESLA headquarters in Holešovice. However, we would also like to return production to the Czech Republic and we are looking hard for solutions to make our products competitive in price.
All of our products are certified for sale in the EU, so we assure you that TESLA Lighting products do not contain the harmful substances you mentioned.
