The 30-metre mast in the car park of the headquarters of Holophane Europe Ltd was adapted to hold new V·Max LED luminaires. Holophane’s high-mast system is the most sophisticated on the market, offering a flexible, functional and completely safe solution that can be used with different kinds of luminaires, including cut-off options.
The previous installation contained 8 x 400 W reflectors with total power consumption of 3.6 kW. Uniformity rating across the entire car park was 0.26, with average light intensity levels of 61 lux. The recommended light levels for low, medium and high traffic in car parks are ≥5, ≥10 and 20 lux respectively.
Replacement of the existing equipment with the V·Max luminaire (lightweight, slim profile) has reduced head weight and surface exposure to wind. The new mast now consumes just 2.4 kW. The uniformity rating across the entire car park is now 0.81, with average light intensity of 40 lux. The result is a huge reduction in bright and dark spots throughout the lit environment. Even with the reduction in the average lux level, global visibility has improved: and with power consumption reduced by 33%. The new lighting solution creates a safe and welcoming environment that encourages its use.
The V·Max luminaire also achieves a significant increase in luminaire service life compared with the previous solution. At 100,000 hours, that’s 5 times longer than the previous MH 400W lamps, whose average lifetime was 20,000 hours. In other words, to provide equivalent service life the previous luminaire would have required no fewer than 40 lamp replacements. That’s a good illustration of the substantial reduction in maintenance costs which the new solution offers.
