HIGH ENERGY EFFICIENCYYpsilon-LED is 40% more energy efficient compared to the fluorescent version, while the lighting quantity remains the same.MINIMUM MAINTENANCEThe lifecycle of the LED unit is at least 50,000 hours, which is more than 30 years when used for four hours a day.CONTINUOUS COLOUR TEMPERATUREWhen the light is dimmed, the colour temperature remains the same (2700 Kelvin). There are no colour changes, such as those known from fluorescence technology.Small rooms can be subjectively enlarged by flooding light over the wall. Ypsilon uses this effect and illuminates a room or wall surface both vertically and broadly. In this case the reduced light housing is secondary and only develops its effect when switched on. The design by Hannes Wettstein is in the form of a “Y” to give Ypsilon its light and unobtrusive character.
