I read that 10,000 Lumes (Is that the correct unit of measure? I know its not watts) are advised for SAD therapy. How many Lumes does this have?

When I use the watt-to-lumen converter, I find that this box is about 2,000 lumens. You can search for yourself here: http://www.rapidtables.com/calc/light/watt-to-lumen-calculator.htm. Remember, this light is 100-watt halogen.

The unit of measure of light output is the lumen (other UOMs like lux, candella, candlepower, or wattage/square area exist). It is a measure of quantity.SAD therapy relies not only on amount, but of quality of light: a specific spectrum of wavelengths, often measured in temperature (Kelvin) or nanometers.This product is intended for waking up, not for combatting SAD.

I still had the box and it doesnt say in the directions or on the box how many lumens. For SAD you need something called full spectrum lighting, I recall numbers like 10k simulate high noon sunlight. The light that is advertised as a replacement in this alarm clock is http://www.amazon.com/Philips-GY6-35-Capsule-HF3470-HF3471/dp/B000LXXSE6/ref=pd_sim_hpc_8#productDetails and its 100watts and 3000K. 3000K is claimed as a helpful treatment for SAD, but to get the doctor recommended dose, your supposed to get closer to 10k for like 10-15 minutes a day. The light itself IS blindingly bright, but its insufficient to totally treat SAD. I also am having difficulty with converting 3000K to the recommended 10,000lux so take my advice with a grain of salt and some good wikipedia searching. And by full spectrum I believe that means all wavelengths of the ROYGBIV, and not just high intensity, i.e. 3000k of just green light wont do it, you need 3000k of all colors and this lightbulkb does have a color rendering index of 100 i.e. it does showcase all colors, but you still need higher intensity (or maybe just sit near it for 3 times as long??)

Since I personally have thrown away the box many ages ago I can't tell you how many lumes this has (which yes, that could be a correct unit of measure) but I can tell you this gets ridiculously bright. I mean... blinding bright depending on what your settings are. From what I understand from therapy I believe this would work. But must say.. I'm not a doctor.. just trying to help answer the question.

not enough, you need full spectrum light @ 10,000 lumens for 20 to 30 minutes. also the item as shown is sold at Phillips web site for 99.00 I don't know if this is some kind of computer error.

D.I.Y projects are the best!!!! So happy to be able to share crafts with others. To answer your question I preferUsing a 40-60 watt regular light bulb (soft) I hope you have a great experience with your project. Good Luck

At about 10 feet, the 127 light is about 5 feet wide and very direct. Insanely bright, and almost uncomfortably so. Double the distance, and you are looking at 1/4 the intensity, but with a 15 to 20 foot spread. It's hard to tell as I don't have a way to test it well right now. It is still rather bright at 15 feet as far as I've noticed. I hope this helps. This would not be a good light to illuminate a whole stage as it is very spot on. I have two right now, and they are actually really good spots for a small 20ft x 15ft to mid sized 30ft x 20ft stage. They need to be at least 8 feet away in my opinion. They also have some really good "sound motion" settings. You will be happy with these lights.

You're welcome.I can say though, there is very little heat given off the LED lights so perhaps that is why they haven't given power density information. What I believe is most relevant from my research is light wavelength - this is what initiates healing and pain relief.It does work - I used this on my dog yesterday. He had a limp (from his arthritis) and today, seems to be back to his normal self.I hope that helps.

It is not "officially" a SAD lamp but that is just because it is not marketed as one. I spent some time looking though medical journals and other scholarly articles and found that this lamp has the same output that has been reported to be effective for many people. But you are not "many people", the only real way to find out if it will work for your SAD symptoms is to give it a try. Yes, it worked for me, and I predict it will work for you. Remember that having the bright light near you is important so you experience the intensity, twice the distance is one fourth the intensity. Also, having the light at or below eye level has been reported to be the best angle. If this lamp does not work you can keep it as a very good desk lamp and buy a more expensive SAD light.

While the lamp is designed for one user, it does have a large field of illumination. The lux level drops off as you move away from the center of the field (lamp), so 2 users who are close together might not receive 10,000 LUX, but a lower level of light. In that case, as long as they are getting at least 2,500 LUX to both eyes, there will be a therapeutic benefit, but the treatment time would need to be longer. For clarification, 2,500 LUX is the lowest level of light and 10,000 LUX is the maximum that have been tested in clinical studies. The relationship between LUX level and treatment time is linear - 10,000 LUX for 30 minutes, 5,000 LUX for 60 minutes and 2,500 LUX for 120 minutes. Of course, these are general guidelines and each user may have different responses to the light, so times will still vary. Always consult your physician before starting any light therapy program to ensure it is an appropriate option for you.

I have only used the brightest setting. Of course, you should not look directly at it. (Really you can't, or not for more than a second.) If you are using this lamp for SAD, I can't imagine why you wouldn't want it as bright as possible, unless you suddenly have more energy than you know what to do with! :)

Dear friend Have a nice day, thank you for your question to me ,My friend ,this link product is SENS CR Flashlight 190 lumens uses CR123A,SENS Mini is 170 lumens.can you tell me you order number?we need confirm your order again,hope you can understand.looking forward you reply soon,any question feel free contact me,thanks!best wish to youSincerely

A really bad application. This 60 wt bulb is quite dim, 240 lumen compared to 700-800 lumen for a standard 60 wt incandescent bulb. 3 of these equal 1 standard 60 wt bulb. Also, the light is very reddish, more of a warm glow than a bright white light. Perhaps OK, if the vanity has 6 or 8 bulbs and you like the orange/red color.

Don't forget that when the distance from a light doubles, its brightness should decrease by a factor of four (Inverse square rule). 50cm is about 20". I hold the light about 12" away as recommended. So yes, it is really 10,000 lux (the measure of energy emitted by the source).

I don't have a way to measure lumens. This light casts a wide beam with spot light in center. I would estimate between 400-500 lumens on high setting. For cost and how long batteries last. Light is well worth asking price.

This is a special daylight bulb, neither CF nor LED. I think it is some type of fluorescent. I don't know about lumens. It is nice and bright, very good for needlework.

Yes, the product is 1000 lumens. I bought others and the same thing happend ( 6 units)

Don't know lumens but a candle would work better for light. Totally worthless for our needs. Remember this light only has ONE LED bulb. We bought two and they were worthless. The ones we ended up with have 19 LEDs. They actually light up the gateway. We ended up giving these to Good Will.

The information about how long to use it each day must be in the packaging. This is a medical device. There is a prescription of X number a minutes at x distance. Yes, you can increase the distance-to a point. If the information is not in your packaging then I question that this is actually a light therapy lamp. At too great a distance it is no longer a therapy lamp - just a nice lamp. Most doctors refer their patients to Northern Lights Technologies.

I don't believe it works for SAD. I use it for an alarm clock as I find the light going on slowly better for me than just an alarm clock.

no specs on the LED bulbs, but if 365nM-370nM is what you are looking for, this maybe a great find for you. I cannot verify but the visible spectrum of light is a neutral dim white, leads me to believe its around 365nM. However, it doesnt seem to work for urine (human or animal) dry or wet.
