Thanks. I already have HID headlamps as OE although the highbeam is QH
and is not much chop. It would be easy to outdrive it.

I was contemplating changing just the interior lights to give me a bit
more margin for when I have another senior moment and walk away leaving
a door only partly shut. There will still be the drain of the radio, the
clock, and the computer system but it might give me more time to find
out I had f*cked up. The last time someone had to come out, pick me up
and take me into town to get a new battery. I hate having to call on
people to help me out.

Think about how much current a single small festoon lamp will use, and work
out how much energy that is... It's not a high current (roughly an amp,
perhaps a bit less) for something like a standard size of 12 volt 'festoon'
style filament lamp, and if that's on all the time it will drain the battery
overnight.

Few, if any, cars actually fully-disconnect the battery when the car is
turned off and locked up since at least some of the electronics has to be
working for the central-locking remote function to work, and any other
devices that need power all the time (alarm, etc.).

Their response time is superior, they are either on or off and
that happens instantly unlike filament.

For automotive use, filament type lamps are fine, the time it takes to
fully illuminate is fuck all
compared to the reaction times of the fella behind you. I dont think the
additional millisecond
will make any difference what so ever!

**It's actually more like 250 - 500 milliseconds.

100 milliseconds is more typical.

It doesn't pay to just look at times to full brightness either. If
you want an incandescent to turn on more quickly, you can also do
that; and more cheaply than with an LED array.

But as far as longevity LEDs are the way to go, should be compulsary for
every Taxi on the world.

**They'll be on all cars real soon.

Nope. Too expensive.

I suggest you do some more research. You have no idea of the real figures
in
this area.

And not all of us have an 'abundance' of Luxeon, Cree, etc. LED devices to
experiment with.

LED's are far superior light emitters than filament lamps because in
filament lamps so little of the energy is converted to visible light, and
most is turned into infrared (ie. heat) - it's not as little as 1 percent
though it is a small proportion.

**And again: BULLSHIT! Repeating the same lie a second time, does not make
it the truth. LEDs are not that efficient. White LEDs are approximately the
same efficiency as halogens. Cree and other high end LEDs are around 4 X the
efficiency of halogens. IOW: Around the same efficiency as discharge lamps.

Even el-cheapo 5 cent LED's (not intended for use in automotive
applications) convert almost all the electrical energy passing through
them
into photons (ie. light),

**Again: BULLSHIT! Good quality white LEDs are approximately the same
efficiency as halogens.

precisely how/where in the very narrow visible

part of the EM spectrum depends on the doping, etc. of the material the
functional part of the LED is made from (not including LED's designed to
emit invisible light such as IR led's).

So yes I know what I'm on about.

**Clearly, you do not.

No I do not have any of these Cree devices,

and I'm yet to find a luxeon device that can used a drop-in replacement
for
any of the standard types of interior automotive lamps commonly used, or
for
any of the standard types of indicator or brake lights commonly used,
without having to add additional electronics to drive them, and creative
ways to heatsink them.

So I don't think that the high-powered LED devices are really the answer
for
replacing the common types of small filament lamps used in most cars, at
least not yet until they can be made into proper drop-in replacement
devices
that don't need special 'interface' hardware, etc.

**It doesn't matter. I'm commenting on your ignorance WRT the efficiency of
LEDs vs. incandescents.

A lot of boats use a specific part of the 27Mhz CB. UHF CB is widely used by

trucks, many landholders and many rural fire services. Also used
extensively by recreational groups such as 4wd clubs for intervehicle
communications.

Yes it's 240 VAC, 50 Hz nominal. The variance is generally specified to be
+/- 10 VAC so in reality the nominal voltage, depending where you are and
what sort of loads are on the local supply grid, will be anywhere between
230 and 250 VAC.

If your laptop has a power supply that works with both supply types, all you
need is the right mains cord with an Australian 3-pin plug to connect your
laptop to an Australian GPO (general purpose outlet).

No, in NZ the plug is the same as used in Australia, and, to be

pedantic, the voltage is 230V +/-6% 50Hz.

indeed. although +/- 6% is laughable when at the end of a long dangly
wire. back in my videogame days in the 80s we used 2kVA 10% or 15% boost
autotransformers to drive the arcade games in places like murupara,
where I have measured line voltages as low as 180Vrms

Ah, but the regulations actually say

53 (1) (b) Except for momentary fluctuations, must be kept within 6%
of that voltage.

They don't define 'momentary', but it is well known that in Murupara
time is measured on a different (slower) scale. So therefore
'momentary' also has a meaning that covers the situation you
experienced
