With the Philips TrueForce Highbay LED HPI you get a real retrofit solution for existing hall reflector luminaires with HPI/HPL/SON. Compared to conventional light sources, this LED alternative offers high energy savings and a longer service life, so that the initial investment pays for itself within a very short time. The lamp design enables direct replacement of high-pressure discharge lamps with the new TrueForce LED lamps without changing the luminaire or the ballast. The two beam angles (narrow and wide beam) and a high color rendering index ensure good light distribution while creating a comfortable and safe environment.
