That's the same logic that dictates about how much money the
school board can save by NOT installing fire sprinklers in a
school building.

Jeff

I dunno about where you live, but I believe Calif. state law requires
that sprinklers be installed, so the school board has no choice. And
even if there was no law, the school board would have to submit the
building or remodeling plans for approval to the state board of
education, and that would be the end of it. If it didn't meet their
approval, it would be sent back to the architect for additions or
changes.

The fire chief told us that the architect did something really stupid.
They spec'd that sprinklers be installed in our computer room, which
is protected by a 'halon' system. So if there's a fire, all the
equipment gets water damaged. Stoopid. But the sprinklers are there,
just in case..

Putting the bulbs in series seems to qualify as an improvement.
Perhaps that would not hold up in court, but we all know the law is an
ass.

No, the law _is_ the law. How the idiot lawyers and judges interpret
it is another matter. Not a subject for discussion here, tho.

Ooh, DejaVu, I think we've had this discussion before...

It's like the UL about pulsing LEDs to get more brightness, it just
keeps coming around.

The bulb savers that I used back in the '70s were varistors. They
slowed down the turn-on of the light. They were low resistance when
warm, and high when cold. There was no diode.

I've seen the diodes, not the varistors. But I have no doubt you're
right. Probably very similar to the inrush limiters used on PC power
supplies, minus the leads.

Hey, I agree with you. But instead, I would have used higher voltage
lamps, two in parallel. Decent LEDs were hard to get back in the
'70s. Another solution might be to use neon lamps.

You mean flourescent lights. neon lamps need a high voltage transformer. :-(
you will not want them for emergency lights, as they are often the cause of
the emergency themselves.
BTW also fluorescent lights have many shortcomings, in a cold
environment(Alaska?) they extinguish and won't start at even moderately cold
temperatures. They need some electronics inside the socket and finally last
not longer than special longlife bulbs, that is 6000h, which is not even 1
year. Of course the efficiency is much higher even if you add the loss of
the electronics (which is usually not accounted for).

Here in my building we have flourescent lights in the emergency lights, but
they are always off and only light up at power loss. They have a 12Ah 12V
gel-battery inside and will power the 5W lamp for not even 24h, not enough
if we have a blackout like in NY. But fortunaterly that has never happened
so far.

Congratulations, you probably bypassed a safety feature. If they're in
parallel, if one burns out the other keeps going. In series, if one
goes they're both out, and the exit sign is no longer visible.

But if he'd have left them in parallel, they most certainly would have
both burned out long ago! :-p

LOL! But hey, makes sense to me. "If Mohammed won't go the the mountain,
