How to use the Sperti Phototherapy Device

The Sperti device comes with instructions. Please read and follow those instructions.

I position the Sperti so that the vertical midpoint of the bulbs (arrow) aligns with the vertical midpoint of my torso, which is halfway between the bottom of my neck and the top of my thighs. I then do 5 minutes on the front and then 5 minutes on the back, standing about 15 inches away from it. And I do this daily. People with fare skin and no tan may need to do less than 5 minutes for a while, and maybe every other day for a while. And if you don't want to bother with those goggles, you can close your eyes and cover them with your hands when irradiating your front. If you instead wear the goggles, also close your eyes.

Once a person has acclimated to the Sperti, if the person has dark toned skin or is very low in D, they may want to do the above twice a day, about 12 hours apart.

And of course you wear no clothes when using the Sperti.

If you don't like the bell sounding when the timer runs out (not necessary because you're standing right there and can easily tell when the ticking stops), if you're handy, you can take the bottom of the case apart (3 screws) and place a glob of silicon caulk on the bell, and that will muffle it.

If all bulbs don't light up when you first turn it on, this may be because one or more of the bulbs is not properly seated. It's sad that the company doesn't have more diligent workers installing the bulbs. To remedy this, reach through the front silver grill, and with your fingers, turn a bulb a little bit in each direction until you feel it click in place. If a bulb is already seated properly, turning it will be difficult at first, and you will feel it "pop" out of place. Not to worry, just turn it back until it clicks back in place. All bulbs should look the same when all the bulbs are seated properly (the writing on all the bulbs will face you the same way).

Q: "I have been putting the lamp on a counter and my torso is in the light, but should I be moving the lamp, for example , to the floor to get the light to different parts of my body?"

A: I've come to the conclusion from my testing that you just need to cover the torso (on both sides of course). Those who say, "No! You must also get all of your legs because they need vitamin D too!!!" do not have a proper understanding of how the vitamin D+ system works. The skin of the legs and feet will benefit from the UVB light that only hits the torso. There is no need to specifically irradiate the lower legs and feet. And to those who say, "No! You must irradiate as much of the body as possible to be able to make enough D!!!" this is incorrect too. I just do the front and back of my torso, and I am able to get to and stay at 64 ng/mL (which is the "sweet spot", which is 160 nmol/L in Europe).
