what distance to put between the skin and the light ?

I put it right on my skin and move it to different areas every few minutes. This is a similar technique used at the spa affiliated with my dermatologist's office.

It cant burn or hurt you. I put it right on my skin. Its hard to find info for home use. But from what I have read. there are no side effects except healing.

Very close. Inches from face and move around to cover whole face. Bulb doesn't get hot. For 10 minutes or so ? Maybe a couple times a week

i would suggest the extra light, due to the fact you dont need so much stregth. But that is just my opinion. I use this for playing guitar. i use a medium stregth.

It should work just fine. If you use the two lights to create soft light on your subject, you won't have a lot of control over the amount of light on your background. So your background may be darker depending on how far away it is from the subject. That might be the desired effect though.

somewhere around the perimeter on the top. put as close as you can to the edge ,otherwise there will not be enough clearance for the light to fit properly

10.5 inches to the lowest point of the light cover. It's a pretty low profile light.

I would go with the low wattage uvb bulb.. and give it a cool spot and a warm spot..

It depends heavily on how bright you want the effect to be and how far away you are able to place the fixture. In addition, there are two different lenses that allow you to have a wider or narrower field of effect based on your needs. In essence, there is no good way to answer. I can tell you from experience that I have had a usable effect covering an entire wall at the end of a large ballroom using the narrower lense in extremely low light, but to do so I had to place the unit itself at the opposite end of the room. Sorry if this is less than helpful...

Use something to create shade It's extremely hard to see laser line in sunlight. Red tinted glasses work ok. But a big piece of card board to create a shadow works best

I'll have to measure my lights, but that sounds pretty close to the overall distance from lens to lamp socket so depth would be determined by how for you want them to stick out past the mounting flange.

It all depends on how detailed you want to see. I would recommend 80 feet to get a clear image that you can at least identify a person with daylight.

Without knowing how much room and depth you have to place the light, yes, the light will light it up; no sweat. You'll have to play the "light placement" game. Hope it works out.

The normal distance from the table to the bottom of the light should be 30"-32". The light comes with lots of cord you can easily adjust the length.

The answer is simply: not very far. If you use all The lighting units in the set and assuming there's no other significant source of light you'll need to be less than 8 to 10 feet max from the subject

Try a small piece of scotch tape, layer if needed. The tape will diffuse some of the light.

Generally speaking if you place the illuminator approximately 35' (approximately 11 meters) from your target you will get a 25'x25' (approximately 8m x 8m) spread. The closer you place it to your target the smaller the spread will get but the denser the light spots will be, accordingly, the further from your target results in a larger spread with sparser light spots. On really large trees I like to place one on each side for full effect. The light spots will penetrate throughout the tree giving it sort of a 3-D result.

I am not sure what the standard/norm is regarding how far the meter should be from the light source, but I would think you put the meter right up to the lens of the flashlight. Light output decreases exponentially with distance (proved in the experiment for which I bought the meter,) but I think that anywhere from touching the lens to maybe an inch out will give you a proper reading. I would put both the flashlight and the meter sensor on fixed surfaces, then look at the reading on the LCD display. Oh, and this is important: do it in a VERY dark room. The ambient light will make a difference.
