Introduction to Mercury
Vapour Lamps - what they are, how they work, what
they are suitable for, and what types are available.
IMPORTANT
NOTICE (August 2010)
NONE
of the lamps on sale today are the
same as the lamps featured in this section - with
the exception of the Zoo Lamps .
Every
lamp - ZooMed Powersun, T-Rex Active UV Heat, and ReptileUV
MegaRay - now has totally different specifications.
We are
doing our best to bring this section up to date but until
this is done, we are leaving the original pages here, because
they still carry useful basic information about mercury
vapour lamps.
BUT
PLEASE DO NOT BUY A LAMP BASED ON
THE UVB OUTPUT YOU SEE DESCRIBED HERE. These old
sets of results and charts are NOT at all accurate and may
be very misleading in some cases.
