Lumos puts the ’flash’ in flash drive with a built-in LED that brilliantly lights up the branding when it is in use. It has a retractable USB connector and a soft PU loop that is ideal for attaching it to a lanyard or a key ring. Lumos has 4GB of memory with a USB 2.0 interface and data uploading is available on request. It can be presented in an optional clear case.
