HELIOS led
20“ round flat disc pendant lamp with direct or direct/indirect
light distribution. One part multi-functional lamp head with
integrated heat sink of die-cast aluminium. Surface power
coated white or black
284
Homogeneous direct/indirect lighting distribution with a light
guiding prism (LGP) body. It absorbs the light fed in from
the side and redirects it upwards and downwards through
integrated circular de-glaring prismatic or opal lens
The optional patented rotor reflector consists of a fixed and
a moveable element. By adjusting the moveable element, the
indirect radiation is increased or reduced from 0 - 28%
Use of long life, 50,000 hour high efficient e2 LEDs at
80% lumen maintenance (LM 80), 48W or 57W power
consumption. Superior color temperature consistency to a
3-step McAdams ellipse, available in 3000K, 3500K or 4000K
with high color rendering index of CRI 85
120V | 277V as standard universal input voltage and various
dimming options available
