Lumen App & Logo

Lumen Light Shop Concept with Logo. Shop that sells lamps and bulbs.

Gives the customer a chance to see the light they want for their room. Kept the logo fairly simple, only a bit of shadow to give it a little depth.

The icon in the top right corner is for picking the colour of the room, not quite sure if it is obvious (does it need some text)? any feedback would be appreciated.
