Will this lamp stimulate vitamin d production?

I don't have scientific proof of that. There's a low emitting heat and it's an LED. Hope that helps.

I was thinking the same thing. I am thinking about buying a reptile light they make uvb

No - this product cannot stimulate vitamin D production because it does not emit any UV light.

Vitamin D synthesis in the skin requires ultraviolet light, optimally in the 290-300 nm wavelengths (UVB). Most SAD lamps specifically filter UV light to avoid eye damage, and humans require UVB exposure over larger areas of skin than just the face. In general, I don't think SAD lights (with their UV filters) are the way to go.Tanning is the first thing that comes to mind, but I don't know if those lights produce the right wavelengths of light. Amazon sells Alzo-brand full spectrum light bulbs (unfiltered, I think) that *might* produce the right UV wavelengths, but you'd have to contact the company to check. Also, the lack of UV filter means a greater chance of eye damage.Hope that helps. Vitamin D synthesis in the skin requires ultraviolet light, optimally in the 290-300 nm wavelengths (UVB).

Intended use (as stated in book) The Lightphoria is intended to make people more energetic, to adjust circadian rhythm and to provide mood relief from the winter blues. This is not a piece of medical equipment. It should be used everyday for a week or more. It has helped me adjust my sleep habits, with that, energy has improved. I'm not qualified to talk about vitamin D production.

no, it's just a light to simulate sunlight. Also, as far as the poor reviews on this lamp, I really like mine. They had an earlier model that wasn't as good, and broke after I had it for three years. This newer design is much better.

I have always used an LED bulf with this lamp...Love the lamp...I use a curly coiled LED...not a lot of electricity for the concentrated light...I read by this lamp a lot

It would depend on your lamp. The bulb has the very small candolier base and is only 3 watts. If you are actually going to use this as a night light, I would recommend caution if using around children because the flickering could cause restlessness and inability to sleep.

Good question. First it would shorten lamps life. Second, you should check with manufacturer about levels of radiation emission, specially UV. Anyway, if I were you I wouldn't, just in case, since those lamps were not engineered for light therapy.

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! :)

Eh no.... it has to be the metal base. http://science.howstuffworks.com/innovation/science-questions/touch-sensitive-lamp.htm

UVB only and good to acquire vitamin D in humans. Once considered purchasing for myself, found something better. Your would need several of this type if that is your goal.

I have used many different watts and it has done fine. I have enjoyed this lamp!!

Yes that's why I like this lampYou have a choice of products which need LED or UV lightIt's easy to use. Just start practicing!

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.

Sorry to say, the answer is no. It is intended for task/spot lighting; for minute handwork. For my purposes, I am a little disappointed with this lamp.

Yes. It's actually nice. Just a suggestion, tho: I'd really recommend that you use an LED bulb for this lamp since it doesn't heat up. Also, using a 40W equivalent LED Globe bulb worked best for me in terms of lighting (that is, if you want your light to be bright but also very relaxing for the eyes) and this bulb, specifically, is really durable and energy efficient. Hope it helps (Pack of 4) G25 LED Bulb 6W, Warm white, 3000K, 40W Globe Bulb Incandescent Replacement, clear Cover, Dimmable, UL Listed, Energy star certified,

Sorry, I have no idea if if has increased my vitamn D production. I just find it much easier on the eyes than typical desk lamps. It give plenty of light that does appear more natural. If you need more vitamn D, as I do, just take it in a vitamn form. I found a gummy one that seems to help w/mood.

No, beacause the heat of the lamp will burn the plastic, exept if the light is led type.

I do not know if the Verilux HappyLite produces Vit. D-3 but I notice a difference in our Fall and Winter months when I use it everyday. I have even had a couple of days when I was unable to use the Lite and still benefited from it overall.

I believe so. As you likely know, we need water, nutrients, air and sunshine. I use a circulating fan for a gentle breeze that continuously runs. Water and nutrients in moderation or as climate dictates. For light I use these lamps and adjustable pulleys for intensity.
