The fibre leather smart book light collection is definitely a great additional piece of art to any home; when closed, this smart Book Light masquerades a natural looking black leather notebook, but when opened it transforms into a sculptural light emitting a wonderful ambient warm soft LED light through the pages. The beautiful, exquisite design opens to full a 360 degrees with cleverly concealed magnets and the lovely soft touch papers are tear-proof and water-resistant that are lighted up by long-lasting LED lights. Inside the black leather cover lies an interior lamp body made from durable, water-resistant Tyvek pages containing high-performing LEDs. The dynamic, multi-functional light can be opened up to 360 degrees and comes with a micro-USB charger. - colour temperature: 2700K (warm-white light) - output: 400 lumen. - power supply: in built rechargeable Lithium Polymer. - battery life: 6-8 hours - product size: 170 x 215 x 25 mm (large) and 90 x 122 x 25 mm (mini)
