Here is a new file I created, mostly because it contains information I
was seeking, and thought others might be interested as well. As with
the previous file (the one on pinball quotes), I give permission to
place this file in the pinball FTP archive, as well as anywhere else.

Common Lamp Info Listing -- Version 1.0
by Bill Ung <ung@filenet.com>
---------------------------------------
This is a listing of lamps commonly used in pinball games, along with
specifications such as voltage, amperage, MCSD (see below) and life
expectancy in hours.
MCSD is a measurement of luminous intensity. It stands for Mean
Spherical Candelas (formerly known as MSCP or mean spherical
candlepower) and is the total light output from a lamp measured
in all directions. It is equal to the total visible energy emitted
by the lamp, measured in lumens, divided by 4*pi (~4*3.1415927).
The idea behind this file is to list alternative lamps based on a
particular application. Most folks know that you can replace a #44
lamp at .25 amps with a #47 lamp at .15 amps if you want your game to
run cooler. But what if you wanted a brighter bulb? Or if your
original bulb was a #555? What are your alternatives then? This file
attempts to answer those questions.
Lamps are grouped by voltage and base ... this is designed to assist
the reader in finding bulbs with the same base and voltage, but varying
other characteristics. Inside of each group, lamps are sorted by
amperage, followed occasionally by MCSD. Flashlamps do not have a
measurable MCSD and are not specified here.
Within each group, the "standard" lamp is normally marked with a "*"
next to it. These are lamps I know are commonly used in games. A
number of groups indicate a "standard" lamp with a "+" symbol, these
are lamps commonly available from pinball parts dealers but are not
known to me for sure as to their usage (they may be jukebox lamps for
all I know). I included them here for completeness anyway.
Speaking of completeness, if there is a bulb type you are looking for
that is not included in this file, please Email me at <ung@filenet.com>.
Include as much information as you know about the bulb type and I will
add it to the file. In particular, we are missing a significant amount
of information about the commonly used #906 bulb. If anyone can provide
that information, it would be greatly appreciated. As always, credit
will be given where credit is due.

Note: The last two groupings are broken apart because although the base
and voltage specifications are similar, the physical glass bulb of
the #1683 lamp is significantly larger than those of the #1251 group.
{1} Used by F-14 TOMCAT on the playfield.
{2} Used by WHITEWATER (and maybe FISH TALES) on top of the backbox
{3} Used by Pin-Bot and Cyclone (I think)
{4} Used by HIGH SPEED (and probably F-14 & HS2) in the beacon light

The other file I'd like to see, but haven't the slightest idea where to
begin, would be a similar file about pinball coils: size, voltage,
relative strength and number-of-coils (flipper coils typically have
two coils in one). If anyone has the knowledge to put together such a
file, I'm sure it would be much appreciated!!!
