Signify unveils LED SON-T with record 210 lm/W

Philips LED SON-T replacement has an efficacy of 210lm/W

Signify has unveiled an ultra efficient LED version of a traditional SON-T lamp with an industry-beating efficiency of 210 lumens per Watt
The Philips Master LED SON-T UltraEfficient A-class lamps are the first A-class HID lamps at 4,000K registered in Europe1, allowing easy replacement of conventional HID HPL/SON lamps with LEDs for road and street lighting.

The new lamps have a similar look, feel and light distribution to their conventional equivalents, and can be retrofitted into existing SON-T fittings. When upgrading from conventional HID lamps, the company says thatis a potential return on investment can be achieved in 2.3 years .
Replacing 100 units of 100W conventional HID lamps with 42.8W A-class SON-T could save around £6,000 per year . The lamps are nondirectional and non-dimmable with E27 and E40 bases.

The company has also introduced an UltraEfficient A-class LED version of the GU10 spot and an A-class dimmable LED bulb for various indoor applications, such as retail, hospitality, and residential. 
The new light sources meet the highest energy label, ‘A’, under the EU’s Ecodesign Regulation, and the Energy Labelling Regulation, which recently came into force. As A-class products, the new lamps consume at least 43 per cent less power to achieve the same output as standard.

The new A-class Master LEDbulbs UE and A-class Master LEDspots UE GU10 consume at least 45 per cent less energy, compared to standard LED alternatives, as well as lasting at least three times as long.

Additionally, the A-class Master LEDbulbs UE are now dimmable, allowing for customisable lighting experiences.
‘With the launch of these new additions to our UltraEfficient lineup, Signify continues to drive the shift from conventional lighting to more efficient LED lighting,’ Michael Rombouts, Business Leader LED Lamps and Luminaires told the Circular Lighting Report. ‘We want to make it easier for our customers to implement innovative, value-add lighting solutions that help customers to quickly and effectively reduce their energy consumption.’
