Hi Luke;
What is required to create ozone electrically is an arc open to air.
The voltage required for this depends on the distance between electrodes
or 'air gap' small gap requires lower voltage. Another way is to have a
very high voltage which produces a corona. This is not quite like an
arc but does cause local ionization of the air around the tip of the
sharp electrode.
Yes UV light can produce ozone (O3) I cannot remember which wavelength
but a mercury arc lamp produces several spectral peaks and one of them
causes ozone formation.
Yes the high intensity UV light can cause burns to the skin and eyes.
As well the ozone is toxic to breathe. On your last comment I am
confused. You realize ozone and O3 are the same thing? If the lamp
claims to produce ozone then it is producing O3. If it claims not to
produce O3 then it cannot be called an ozone lamp!

Excellent. I appreciate all of the input. In the past, I've used UV
sterylizers in my marine aquaria, but never really had a need for
indoor air purification. Now I do, so I'm examining my options. First
a few points/questions...
* very high voltages are required to create O3, correct?
* UV light between certain nanometers creates O3?
* This ozone light could also be harmful to people, as well as
eliminating airborne pathogens?
A side note, I think that the ozone light brags about its safety, and,
in fact, states that it doesn't actually create O3.
Thanks,
Luke

High voltage arcs produce ozone and also produce nitrogen oxides
which are not healthy. Mercury arc lamps produce enough UV to make
ozone for sure. So does a laser printer. Usually arc lamps have an
outer envelope to keep air away from the actual bulb. UV lamps
bright enough to make O3 are dangerous to the eyes. What else
about ozone....let's see, ozone disolved in hot deionized water is
hell on wheels for anything organic. Works like gang busters as a
cleaner for semiconductor wafers. Environmentally freindly! Liquid
ozone is something like nitroglycerine, watch out for that one
when using cryogenic pumps with oxygen plasmas. Warm them slowly
with a nitrogen purge....don't let that ball of frozen ozone melt
and drip or we'll see you in the next world. I suppose liquid
ozone would beat liquid oxygen for starting a barbeque...lol
Don't try this at home kids.
Fun with ozone....

UV light (when powerful enough) can sterilize many things. There are a
number of water plants that use UV for
sterilizing. I dunno about the "Ozone Lights" doing much good on the O3
side (namely, is O3 a sterilizing agent?).
I think there are better ways to make O3 such as direct electrical arc
(jacobs ladder). Some ion machines also
produce O3.

Hello all,
I was just wondering if anyone has heard anything
about the effects of these "Ozone Lights." I guess
that they don't actually create O3, but they do kill
airborne pathogens. Most of the online literature that
I've found goes back to one study that showed this
light effective in killing E. Coli bacteria in
clinical trials. Anyone have experiences with this, or
anything
similiar?
Thanks,
Luke
