The final package design uses the bulb as a graphic element together with a shape symbolising the sun. This image is a photoshop rendering of the package.
The final name comes from the rare Finnish word kajo, which means the soft light just before sunrise. Similar word in English is be dawn. kajastus —> kajo —> kaio
The logo is a modern wordmark with a shape of the sun inside the “A”.
The package design project consisted of a lot of sketching and planning, some 3d design and prototyping with the laser cutter. The idea is that the supports for the bulb are folded from the same cardboard piece, potentially saving costs.
Some box prototypes. Iteration was necessary to get everything to work
