About
Lumo is an always-on night clock with a huge time on a dark screen. Set it on the bedside, dim it, and read the hour from across the room. The clock stays on all night.
It works as a Shabbos clock. The screen stays lit, the time stays large, and a short note can sit on the clock for a door code or an address.
A noise machine is built in. Play white noise, pink noise, brown noise, blue noise, grey noise, or a soft fuzz. The sleep sounds fade in and out, and the volume stays where you left it.
