Designed by Herkner in 2014, the Oda lamp is one of the brand's most popular products and is available in three sizes and a range of colours.
The collection is inspired by photographs of industrial water towers taken by German artistic duo Bernd and Hila Becher.
Much like these structures, the main body of the lights has a rounded form that is supported by a metal frame.
"Like the silos and water towers of which they are inspired, Oda's simple forms appear both subdued yet bold," explained Pulpo.
Bubbles, streaks and other variations in colour and size are formed as part of the handmade process – giving each piece a unique quality.
The Oda collection consists of a table light, a low floor light and a raised floor light. Readers will have the chance to win either one of three table lamps – available in smokey grey, aubergine or amber – or one of the medium or large floor lamps, available in grey.
"The Oda lights utilise deep tones and atmospheric transparencies to create a glowing centrepiece in any space," said Pulpo.
"Their sleek frame lets the curvaceous tones of the handblown glass shine," the brand continued.
Sebastian Herkner, who has had a long-standing partnership with the Pulpo, founded his studio in 2006, which specialises in furniture, lighting and accessories, as well as spaces and installations.
Other collaborations between the two studios include a "playful and brutalist" collection of furniture and tableware and a collection of metallic containers.
The raised floor light retails for £1,740, while the low floor light and table light are £1,330 and £620 respectively.
Five readers will win one lamp each. The entire collection is available for purchase from Pulpo's online store.
