GTI Media is an internet media company specialising in graduate recruitment and careers information. Lietcorp provided GTI Media with stunning new office LED lighting that has been optimised for a web media business.

Energy consumption has been halved and old, worn-out fittings have been replaced with our elegant Liet Linear system that offers functional, useful light to support visual tasks.

The 30-year-old building posed unique challenges as it featured virtually every ceiling type imaginable, including an 8 meter glass atrium, a standard 2.7 metre suspended ceiling and a 4-metre-high open-plan office with exposed ducting and pipework.

Lietcorp’s LED lighting was installed in all areas of the office, including the social areas, café and meeting rooms, making this the UK’s first full office LED lighting refurbishment and the office was in full use throughout the installation.
