Know I've seen it, just can't remember the name - alarm clock that slowly lights up?

Factual Questions
1

What the heck is the name of the alarm clock that slowly lights up, like the sun rising?

I’m thinking about getting one for my husband, does anyone know how well they work?

I’ve seen these advertised in an airline seatback catalog (if the link doesn’t work, the manufacturer’s name is Bio Brite, and you can Google for it). I vaguely remember a different company’s ad for a similar product in another magazine, too, but can’t remember the details now.

Haven’t used them, so can’t help you there.

I have the digital model. It is a great idea and it great to wake up to but…

this clock has broke once and fixed under warentte

when there is a power failure the clock goes to 12:00, alarm goes to 7am and I have found that after the powerfailure you have to cycle through 24 hrs+ to set the time and have the alarm work the next morning.

if you go for this model plan a ups for it
