In the old days a tungsten light bulb typically only had one filament

only one was turned on at a time to prevent thermal issues.


Perhaps you haven't heard of 3-way bulbs.

What? You want be to give you all a complete education for free? You
have any idea what the word "typically" implies? Yes, and stop light
bulbs have two filaments which if your tail lights are on (at night) and
you stop, they BOTH come on. But it is not a "typical" Edison bulb.

So what does this have to do with high powered LED flashlights being
fluorescent while all you guys are talking about PN junctions and their
currents?

Are you too stupid to understand what YOU wrote?
You used the word "typically" referring to to single filament bulbs,
not double filament bulbs.
And you wrote " if there were two (hi and lo beams for example) only
one was turned on at a time to prevent thermal issues. "
Which is not generally true, and wouldn't even be true if you had
inserted the word "typically".
