Lucellino LED TRI-R
Average dimmable LED retrofit bulbs become less bright when dimmed, while the TRI-R bulb also changes the luminous colour (2500 - 2900 K), just like halogen bulbs do. The bright spot of the bulb becomes reddish. Also, it is actually in the middle of the bulb, not next to the socket. When defining the colour rendering Toshiba Materials used the soloar spectrum as a reference standard. The new LED bulb for Lucellino is the first full-fledged replacement for all admirers of the light bulb, hardly distinguishable from a halogen bulb, and a technological masterpiece.
