The 4GLS is one of the major components of the Centre for Accelerator Science Imaging and Medicine - CASIM - which is to be based at Daresbury Laboratory in the UK. The 4GLS is a suite of accelerator-based light sources designed to complement the ESRF and DIAMOND third generation sources by providing state of the art radiation in the low energy photon regime - from the far infrared to the extreme ultraviolet. In the initial phase 4GLS will have three main components: At its heart will be a low energy (800 MeV) energy recovering linac which will provide optimized radiation from a variety of undulators. Bending magnets radiation will also be available for those experiments for which it is the source of choice. Incorporated in the energy recovering ring will be a special high precision undulator that is the core of a cavity VUV free electron laser. The third part of the system is a stand alone infrared freel electron laser. This talk will cover the basic aspects of the design and give an overview of the applications of such a groundbreaking source. Further details may be found at http://.www.4glas.ac.uk
