Philips goLITE BLU - Alarm Clock - SAD Blue Light Energy Therapy Device -HF3330

As well as waking up to light, you can trigger an impromptu session manually. A temporary pause in a session can be added by pressing the power button briefly, or turning the intensity down to zero, though if you leave it paused and running on battery power for over five minutes, the goLITE BLU will automatically power off.
