Ive seen them but you have to push a button to make them light, post
back if you find one that just stays lit, I just got a Weather
thermometer with clock at HD, but again its dark till you push the
button but it has an RF set clock so it never needs setting.

Quick look in the Tesco Direct catalog (it just happened to be the
nearest) page 444 at least 3 of the 4 across the top of the page have
luminous hands. The LH one looks to have luminous figures as well.
The RH one dots for the hours.

they don't use radioactive luminous paint any more, so 'glow in the
dark' watches and clocks are a thing of the past.

I've come to the same conclusion. The paint often *looks* like the
proper luminous stuff, but it isn't. The clock I bought recently has
some kind of fluorescent paint that glows green for a short while after
the light goes out, but not long enough to be of much use.

The non-radioactive paints need "charging up" with decent light, kept
in room with the curtains closed or only brief artifical light source
they are dim. The best way to charge up these paints is with a UV
light source, say a bank note light or one for making the invisible
security pens visible.

There are still radio active glow in the dark things in the market.
Mostly emergency signs and the like, they use tritium IIRC rather
than radium.

The ones with crappy luminous paint are easy to get from the usual
places. If you want one that really works though, you'll need spend some
money and get a tritium one:-

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=220571309038

A bit of digging might get you one closer to home. try Googling for
Luminox, Traser or Tritium

Cheers,

There are alarm clocks with tritium dials. Did not google far but they

To stay lit permanently would run down the battery too quickly, so
that's why you have to push to get it to light.

Not completely. Bad if source is ingested, bad if source is inhaled in
form of anything that sticks in lungs or is absorbed into the body from
lungs. OK if in a closed container and low energy, as is the case with
tritium.

Yes but unlikely and does not compare to the old radium dials that

Tritium is very good, but expensive.

Zinc Sulphide is the dissapointing old glow in dark stuff.

Strontium Aluminate is much, much more effective, non radioactive,

I don't know about that but we have an alarm clock that displays the
time in red on the ceiling of our bedroom. it's not bright enough to
disturb our sleep but it's great if you wake in the night and want to
know what timwe it is.

Why ever not? They work, I have one. Clearly you can't say the same
about everything at poundland but if Argos can sell 'em for £2.50 then
£1 is probably about the right price.

I am surprised that there is nothing like this available. It shouldn't
be that hard or that expensive to design something that has a small
photovoltaic cell to charge a small battery during the day, even from
ambient light, and then dimly light a set of LEDs when dark using a
low-power circuit to generate a low mark/space ratio driver to conserve
power.

Not done the sums though so I could be way out.

There are very few battery clocks that don't use a crystal and a *digital*
divider to keep the time.

There are some, but that's not really relevant, other than Dennis
trying to twist the argument for his own ends, again.

The terms analog and digital, in refererence to clocks, usually refer
to the display. I don't give a shit what technology is used to keep
the time so long as it meets my needs for accuracy.

Not entirely. Some time ago (perhaps now 10 years) I wanted such a
watch. I went through a number (agreeing with the supplier they'd come
back to him if they were not really "luminous") till I tried a Sekonda.
The hands were luminescent but *the dial was properly luminous*. So I
wrote to Sekonda, asking how they managed this and whether they could
source luminous hands. They could and did; I could not have had better
service. When years later it broke they fixed it FOC, and told me that
they had also replaced the battery as a courtesy.

I thought their slogan was a joke, but it's been absolutely right IME:
"Beware expensive imitations".

I have a relative that is upper middle management of a global
electronics manufacturing company. One of their main plants is in
the USA and is quite busy and profitable. The big electronics
devices they manufacture are in high demand AND one of their
biggest locations where they ship is mainland China. Imagine
that: a USA-based manufacturing plant shipping electronics to
China.<grin>

In one high street I've seen a Poundland, a 99, a 98 and a 97p shop.
There are at least three other chains that follow similar themes.

Charity shops might not have enough stock but they have plenty of
volunteers, the Govs "New Deal" for the unemployed forces them
to volunteer for charity shops or lose their job seekers benefits.

and getting it back on topic, 99p stores have a calling card which seems
reasonable value, seems to have been provided by TalkTalk?

I don't think there is much low cost manufacturing in Hong Kong any
more. Twenty years ago maybe but now most of that has been moved to the
mainland and Hong Kong seems to be mainly financial services and the like.

India is another matter. Over here I seldom see anything marked as
manufactured in India except perhaps clothes. But I can't for sure say
why. My perception is that the Indian growth is based more on things
like call centres, software services outsourcing and heavy engineering
like steel making and cars. None of which are sold in Pound Shops.

Certainly in my professional capacity I get much spam offering
manufactured goods from China and software subcontracting from India but
not vice-versa.

I bought a pack of 3, not one of them worked well enough to be any
use. All kept losing big chunks of time - and yes, the batteries were
good.

I often see tools manufactured in India and Pakistan at the Harbor
Freight store. It reminds me of what I used to see many years ago
coming from Japan then years later from Hong Kong. Inexpensive and
roughly finished products seem to come from countries as they first
hit the global market then later, as the manufacturers gain experience,
the products improve in quality and value.
