Philips HF3520 60 E Wake-Up Light With Colored Sunrise Simulation

I just used this for an inside cabin on a cruise. I loved hearing the birds chirping as a wake up Call when we were out at sea and no birds were around in actuality. Two alarms are programmable one color, sunlight brightness gradually occurring variable settings for time and sounds you can use 12 or 24 hour clock time setting. You can access the manual online
