'Balloons' is a new collection of lights designed for Czech firm BROKIS by Dan Yeffet and Lucie Koldova.

We've featured this design duo before, and this new set of interior lighting sees Yeffet and Koldova further exploring the possiblities of glass.

We really like the playfulness of their work, and if you didn't see them before, take a peek at our coverage of their 'Muffin' lamps here. These shots of 'Balloon' were taken at this years' Designblok event, where you can also see Yeffet and Koldova's new tall versions of Muffin (also designed for BROKIS) in the background of the second and third images.

Simple and and rather timeless in form, the original idea for 'Balloons' stems from the concept of transparent invisible balloons with a floating reflector.

The series is composed of three pieces, which range in size from table top lamps to two large floor models.
