Epson EMP-1715
Light–Eficient Lamp Technology —E–TORL
One of the crucial factors in the EMP-1715's capability of providing up to 2700 Lumens is the incredibly efficient E–TORL (Epson Twin Optimised Reflection Lamp) technology. Designed to minimise light leakage — a primary cause of lamp inefficiency — and minimise light diffraction, E–TORL–based lamps are so small and efficient as to be well ahead of their time.
