BSD rounds up the latest lighting technology and applications, from compact metal halide lamps to floodlight masts for Lord’s.
Ansell Lighting has introduced the Neptune T5 semi-recessed modular luminaire for hospital and healthcare office projects. The 600 x 600mm luminaire uses switchable T5 high frequency control gear as standard and has various dimming options to reduce light levels in unoccupied areas. The unit is available in both three- and four-lamp formats with either 14W high efficiency or 24W high output control gear options. A maintained emergency option is also offered. All units are suppled with colour 840 triphospor lamps.
The Powerstar HQ-TS Excellence metal halide lamp is smaller, more compact, and offers up to 15% more light than its predecessor. It also has excellent colour rendering properties. The lamp has an expected life of 12,000 hours, but this can be extended to up to 16,000 hours by combining it with Powertronic electronic control gear. The lamp is available in 70W and 150W as well as three light colours: warm white, neutral white and daylight. It is suitable for indoor use in hotels and sports halls and outdoor applications including floodlighting.
JCC has expanded its range of low energy downlights for residential, retail, commercial and hospitality projects with the introduction of Fireguard MLED. The 7W unit uses Philips LED lamp technology with a lamp life of 40,000 hours to offer up to 80% energy savings compared
with standard halogen or GLS lamps. The fire-rated luminaire is available with either 25° or 40° beam angles and can be used with conventional dimmers. The range includes an IP65-rated shower light which is suitable for Zone 1 in bathroom areas.
Philips’ ColourReach Powercore technology has been used as part of an LED lighting scheme at London’s County Hall. With an output of more than 5000 lumens over 150m, the technology is claimed to be the first LED architectural floodlight powerful enough to illuminate large-scale structures. The installation at County Hall, on the South Bank, uses 16 fixtures, positioned at intervals between the columns with four modules spaced along the facade itself. The units are controlled using a Philips iPlayer3 which enables the lighting to be changed to reflect the brand colours of clients that hire the space for events – and to ensure the building remains a riverside landmark at night.
