Lumie lights join The Coldest Journey

‘The Coldest Journey’ is Sir Ranulph Feinnes' attempt to be part of the first team to cross the Antarctic during winter. The journey is from the Russian base of Novo to Captain Scott’s base at McMurdo Sound, via the South Pole, and will mostly be in complete darkness. Lumie, light therapy leaders in this specialist area of health and well-being and inventors of the first dawn simulating alarm clock (wake-up light), have announced that they are supplying two Lumie light products to be used throughout the expedition which is set to span over 2,000 miles.

Jonathan Cridland, CEO at Lumie says “We are delighted to be involved in this exciting and unique expedition and to be speaking with 'The World’s Greatest Living Explorer' (Guinness Book of Records) Sir Ranulph Fiennes. It is important for us to share that light therapy can be used by the fittest and healthiest people as well as those who are suffering from SAD and winter blues. We are proud suppliers to British Swimming and equally proud to be providing our products to ‘The Coldest Journey.’


The expedition team will be completely self-sufficient as there is no search and rescue service available as the cold and dark conditions are seen as too difficult for safe entry. Lumie Bodyclock Active and energy light Arabica will be positioned in one of the two specially developed cabooses (sledge-mounted work and living quarters.)

Sir Ranulph Fiennes says: “My team and I will mostly be working in complete darkness for the 6-month expedition and with nothing but the stars providing us with light. The Lumie products will assist us hugely on a day-to-day basis. We fear that the lack of daylight that we will be receiving may prevent us from working to our full potential in the –70°C conditions but the Lumie Bodyclock and Arabica lightbox will provide the right light to help maintain our sleep patterns and keep us in good spirits.”
