Street and Area
LIGHTSPREAD
Philips Hadco articulating head™ the core of Lightspread technology is the unique 6-position articulating head that is standard on each Philips Hadco streetlight.
The articulating head allows for precise positioning of the coverage area and all but eliminates hot spots and waste of light due to overlap or random spillage. The field of illumination is uniform and light intensity is nearly the same at a distance of 2.25 times the height of the lamppost as it is directly beneath the source.
Note: In comparison, a typical sodium fixture will lose 40% of its light within the fixture head and 50% of the remaining light is focused in a hot spot directly below the lamp.  |

OptiAC
OptiAC power conversion technology ensures that every possible unit
of energy is transformed into light.
The OptiAC converter provides a conversion efficiency of 96% with
a power factor of .98 and very low total harmonic distortion (<10%).
The unique age compensating algorithm ensures that photometric output
is uniform over the long life
of the fixture (minimal lumen depreciation).
OptiAC goes a step further by automatically adapting to electrical inputs varying from 90 to 300 VAC.
Midnight Dimming
Midnight dimming is a totally unique option that can be integrated into Philips Hadco fixtures. Without any outside prompting the Philips Hadco microprocessor will adjust to prevailing lighting schedules and dim output to 50% intensity from 23h30 through to 5h30 further increasing energy savings.
Forward compatibility
Philips Hadco fixtures are designed to be completely forward compatible. The modular design allows LED arrays to be easily slipped out and replaced. By design, the OptiAC converter will then automatically adapt to new array power specifications and adjust power flow instantly.
