likai99sioc-ga,
I believe the lamp you are looking for is available from a company
called Osram, who makes specialty bulbs, many of which are used for
scientific and technical applications.
In particular, Osram offer about 10 mercury-vapor bulbs in the wattage
range you specified, and these have been used as high-pressure mercury
sources in photochemistry experiments. The bulbs are designated by
the prefix "HBO".
For instance, here is a description of one bulb right in the middle of
your wattage range:
==============
Product description: HBO 200W 49-57V L2 FS1
HBO Mercury Short Arc Lamps
HBO Lamps for Technical and Scientific Applications

Illuminated area in mm 0.6 * 2.2 mm
Luminous output in lumen 10000 lm

===============
The direct link to this particular bulb is here:

though I suspect the link may not stay viable by the time you click on it.
To see all the bulbs in the HBO series, you'll have to click through
the infuriatingly cumbersome Osram catalog:
http://catalog.myosram.com
On the left hand side of the page, click-through on the following categories:
-- Display/Optic
-- HBO Mercury Short Arc Lamps
-- HBO Lamps for Technical and Scientific Applications
and you will ultimately get to the full list of HBO mercury bulb offerings.
You will need to contact Osram directly to find a distributor in your
neck of the woods that carries the HBO bulbs, or to order directly
from Osram:

Best of luck.
If there's anything more I can do for you on this, just let me know by
posting a Request for Clarification.
