I'm sure in the work you do, you need those full standards that detail
everything. All that I'm looking for is a basic table of information.
I don't want ANSI specs. A summary of just the basics is all. For
example, what is the current of a 150 watt HPS lamp. And what is the
minimum voltage it can operate on. Same for other wattages of other
types of bulbs. I'm not interested in exotic bulbs, just the common
ones used for indoor and outdoor illumination.
I've looked at product offerings of bulbs and ballast for various HID
lamps. There appears to be basically one kind of ballast for any given
lamp technology and wattage. So it would seem the proper operating
current for a given technology/wattage is just one number. And there
are not that many different wattages. All this information for all HID
lights could apparently be put in one table on one page. Fluorescent
seems to be more complex due to a wider variety of bulb types and what
I call "sub technology" (e.g. bi-pin vs. mono-pin, instant start, etc).
But even so, it doesn't appear that there would be more than a page or
two for the major common fluorecent types one would see for general
illumination in a home or office.
If I bought _all_ the engineering standards documents that would provide
all the info (operating current, minimum voltage, maximum voltage of that
is a factor), how many total pages would I end up with, and how much would
that cost? I'm sure this basic information has been compiled somewhere.
