How does this compare to the wake-up lights which come on gradually in the morning? Do they have the same benefits? Can this be used to wake up?

This does not come on gradually, but once on, it DOES help you wake up..Like walking outside on a sunny day seems to get you breathing deeper & helps all your systems ramp up for the day.

I think my mother uses it at breakfast. She sits with it on the counter for half an hour or so in the morning while she's eating. This does not have a gradual wakeup function, just on/off. Hope that helps. (she loves it)

These lights are what is called "full spectrum lights." If you take 20 minutes, or what the scheduled time is on the machine it is as if you were out in pure sunshine. This way yourbrain thinks that there is more sunlight in the day than there really is. If you need more light in the day this is the machine to purchase.

The wake up lights do help me wake before the alarm. I guess you could use these to wake up, but I use mine independently. The wake up device I have is attached to a bedside lamp with a regular wattage lightbulb. That's the difference for me. This thing does the full-spectrum light.

With the app, there is a feature to set an "alarm" so you can turn the light on with a certain intensity/color. It would be a pain, but you could create 5-10 alarms separated by a few minutes, each one brighter than the next.

The HF3520 has a 2nd alarm setup which, in theory, could be used to wake up your mate, or as an alternate setting (weekends, school days, etc). The HF3520 also has a sunrise simulation which changes the color of the wake-up light from a dim reddish glow to the same slightly yellow white glow as the HF3510. That's why I opted for the HF3510 since the extra features weren't useful to me. Over the last month, the pricing has fluctuated a lot for the HF3520 but not for the HF3510. The pricing seems to have dropped for the HF3520 to the point where it could be cheaper to get that model over the HF3510 had I not gotten a good deal. Do your homework before buying.

No. It has a low or high setting. You would have to put it on a timer to have it turn on as you wake up and then it would be at low or high. I hope this helps.

Has anyone else tried the "bright" mode trick? Any comments on the difference...

Yes, as soon as I wake up (at this time of year it's still dark at 6 a.m.) I use it and I set the timer for 30 minutes and use the ion thing too. It really wakes me up and gets me going. But I had to change how I use it in the late afternoon when it starts getting dark and gloomy because it was causing me to stay awake at night. So you will have to experiment until you find the right combination that works for you. You should begin with the shortest settings to see how that goes for you. Please read the instruction book that comes with it because people with certain disorders should not use it at all. Good luck!

I chose the HF3520 because i liked the harmonious round shape (it looks like a little sun as opposed to a lighthouse or something). From what I have heard there is quite a difference in the colour of the light between these 2 models. Some people say they prefer the older model because the light is warmer. But from what I have read on light and circadian rhythms, a bluer or cooler light is actually more effective at waking a person up. Either way I find the colour of my 3530 to be quite pleasant, it glows red when its dimming but is quite bright and white when on full. intensity of sound and brightness are both adjustable on this anyway.

When turned on, you simply place the light over each section of your face and hold it there for about 3 minutes, then move to the next section. I do this every night before bed. I actually get into bed about 30 to 40 minutes early and sit on the bed before turning in and use the LightStim while watching TV. I use it over every part of my face and on my neck, except over my eyes of course. I have used it every night, except for one, for the past six weeks and I can tell a difference. It usually takes me about 45 minutes. If you are not going to commit to doing this every night, then I wouldn't buy it. But I have seen a difference.

Hi - no this version doesn't have the option to go from light to dark at night. It does make a great reading light at night, then just click the raised button and it goes dark in a couple of seconds. I have this light behind my bed on a tall nightstand and the off button is still very easy to reach up and turn off by feel. Really like this lamp - got it a couple weeks ago and it's made waking up SO much easier, I feel so much more awake, and calmer, in a better mood all day and it helps the depression brought on by these long gloomy winter days. The alarm options are very nice: radio, birds chirping or some sort of alternative sound which I use and it's wonderful to wake up to.

PM seems to work a little slower which is good since you may need it later in you sleep. The other works fast,I say,within one minute. I like them both!

Barbara, from what my MD has told me (he's the one who suggested I get the light lamp), it's only good to use the light box in the morning after you wake up, for about 30-45 minutes. It's not meant for use all day long in a low light environment. Hope this info helps...you may want to ask your doc about it!

If you want a light that comes on while you are asleep, look for a Dawn Simulator. There is a nice overview of this option (with research information related to it) on the following website: http://www.psycheducation.org/depression/LightTherapy.htm#dawnsim.

I hate fluorescent lights too but LOVE the this light! Just don't stare into it..... It is such a great way to wake up in the morning! I love it!

Not really. They do give decent light right away, but they get to full brightness over about a minute. Where I use them, it's not a problem, but if it was over my desk it might bother me. (Interesting that I now see two people said yes. We all must have different ideas of "instant on" means.)

It doesn't appear to be very blue. It seems like the lower brightness settings have very little to no blue, and blue increases a little bit as you raise the brightness settings. I know the blue thats found in computer screens disrupts my sleep, and I haven't found that to be the case when I use this light (even when used as a night light). The higher settings, I've found, do give you energy similar to sunlight...Tried out the alarm this morning, it works like a charm

As others have said, if you have the alarm set, the clock display will dim once the light gets down to a certain darkness level but it does not ever go completely off as far as I can tell. It is definitely not as bright as a traditional alarm clock display.
