We recently installed slot lighting in the Pharmacology Building at Oxford University, this is quite cutting edge in lighting terms.
Here is how Zumtobel describe their Slotlight Infinity range:
“With SLOTLIGHT infinity product range, Zumtobel combines pure feel-good light with excellent lighting effects in one LED light line. Light is not only directed along homogeneously lit lines, but also skilfully guided around corners. The successful solution is now being extended by intelligent innovations which considerably facilitate handling and lighting design: with SLOTLIGHT infinity, Zumtobel presents this spring the world’s first consistent LED light line – opening up a new dimension in design.”
