Improving the well-being of high-Arctic residents by modifying light exposure while saving energy
We conducted a lighting retrofit study at Canadian Forces Station Alert (latitude 82°30’N), the world’s most northerly, permanently inhabited settlement. Existing recessed fluorescent troffers with nominally 6500K T8 lamps on electronic ballasts, providing ambient lighting in selected offices, were...
