[Rockhounds] 3 wavelength UV light - was fossils

[betdav97 at aol.com]

Tim,
? I have the same light, but if you are going to purchase a new one, 
I would suggest the triple light, which contains a medium wave
length. Some calcites really get excited under the medium wave 
length. They jump up and down and wave their rhombs. Sorry, I
just couldn't resist,
dave

Tim,
A three wavelength UV light has short, long and mid wavelength range UV
lights in a single package.  I know of two brands that are available; "Way
Too Cool" and "UV Products".  Examples can be seen at
http://www.polmanminerals.com/html/way_too_cool.html
and
http://www.polmanminerals.com/html/uvp__llc.html
There are other dealers as well.  George Poleman's website just came up
first when I did a Google search.

Note that I have a three wavelength Way Too Cool unit (36 watt) that I use
for display purposes but for field work I use a Superbright SW UV lamp and a
LW UV flashlight (with a LW filter attached to get rid of the visible
light).  Unless you are really into fluorescent minerals I would consider a
LW/SW combination unit since that will give you the most bang for your
buck.  On the other hand nothing with any decent power is inexpensive.

I hope that this was helpful.
best regards,
Nate Martin
Lexington, MA
