Summary: Hi. I have the HF3580 & HF3585 models, so my review is for others whom are interested in the newer models. The Dusk & Dawn simulations do help you get outta bed easier! This lamp is great for ppl who work @ night... This will help you. Creating a circadian rhytme is a good way to minipulate your body to wake up. These models come with 4 sounds (including FM).
Summary: I've been researching therapy lights for years and finally splurged on this one. I ADORE the sunrise sunset feature and the choice of "soft" alarm choices; birds chirping, ocean waves, rainforest, etc. It truly is so much more pleasant to wake up with a sunrise and calming natural sounds. The light serves as a SAD light as well as awesome task lighting. I rarely buy two of anything but I did order a 2nd one for a gift. It's hefty, substantial, and has a snooze function.
Summary: Was looking for a radio alarm clock and liked the idea of how it gently wakes you up. Radio worked great and liked the realistic nature sounds, especially the bird chirp. While I didn't notice much of an effect in the morning with the gradual light, I really liked the adjustable brightness that made this alarm clock serve as my bedside table lamp too.
Summary: I purchased this Wake-Up Light after my previous light stopped working. I was excited about the potential "upgrade" but quickly was very disappointed. It is true that the quality of light is very nice and the streamlined look is aesthetically pleasing. However, the down side of the minimalist settings means that it's impossible to operate the clock without picking it up in bright light. For an alarm clock, this is quite a pain.
Summary: This clock definitely has more features than I imagined it would and it has a very modern look which I really like. It allows me to wake up without feeling so cranky which is the greatest benefit for me :-)
Summary: Definitely "eases" you out of sleep instead of jolting you awake. I am the complete opposite of "morning person" - I have an average of 7 traditional beeping alarms on my phone over the course of an hour an a half to ease me awake, but am always snoozing. The first week with this wake-up light, I noticed a difference right away and felt more awake by the time the noise was at the level I wanted to be awake at.
Summary: I am NOT a morning person and do not ever want to get out of bed. I take depression meds and definitely do better in the summer when there is more light which is why I decided to purchase this "alarm" clock despite the cost which I feel is expensive. I am retired so there really is no need for me to have an alarm but if I don't I will sleep until 10 am. I have it set for 7:30 am and find I am out of bed by 8 am. I am more motivated throughout the day.
