Weighing just over 12kg the OPTI K4 is lightweight, cool and deceptively powerful for a projector of this size.

Improvements to the Philips MSR 575/2 metal halide lamp and new coated condensor optics inside the projector now enables the OPTI K4 to achieve an impressive 5,200 lumen light output with an average lamp life of 1,000 hours and a higher colour temperature of 7,200 K. If longer lamp life is preferred over light output the Philips MSD 575 or Sylvania BA 525 SED lamps can also be used. Lumen output is reduced to 4,500. Average lamp life is increased to 2,000 hours.

Whichever lamp is used the internal electronic ballast with automatic voltage sensing allows the OPTI K4 to be used anywhere in the world.
