Thought this belonged in GD! I've got an olde Binatone Moontime Mk. III Alarm Clock and that light gets stupid hot and is warping the case with it's focused 12 WATT heat. Anyone know of a drop-in modern replacement I could use? Sticker says 12 WATT 12V and the image below is the measurements.

Check the metal can for markings on it's voltage as from what I remember that style of bulb came in voltages from something like 2.5v to 15v as it was a common fitting found in all sorts of things from 2cell torches to alarm clocks and I think even some car accessories.

Google suggests you can get them in led versions from 2v to 18v with relative ease for a couple of pounds.

Looks like an E10 to me as well. I don't think it has to be 12v either, you can choose a lower power for less of a blinding effect when in use :)

I'm not sure you can choose a lower voltage, as it'll use what's supplied and if the voltage supplied is higher it'll burn out.
I think you could choose the higher voltage version (as long as it was the same current) for the incandescent versions and it'd be a little dimmer and possibly last longer as it wasn't being pushed as much, but it's a very long time since I used them (I think it must have been 20+ years ago, about the only thing I've still got that uses it is the light on a cheap case compressor, and an ancient car spot light).



[edit]
I'm getting flashbacks to sorting out christmas lights, as the tree lights had about 5 different body styles (at least) and something like 4 different voltage options for the type with some of the better brands using a colour code on the base, and the standing decorations that used halogen bulbs and you'd have to play "hunt the bulb" as you looked for the correct size, shape of reflector, voltage and wattage for some of them.

Something to bear in mind is that some LED bulbs can get quite warm too. As @Werewolf says, go for a higher voltage bulb - this will reduce brightness and heat too, meaning it will last longer as an added bonus.
 
Carboot.... I was at one a few months back when some old chap brought a load of them, I looked at him puzzled; and he explained that 12v bulbs are hard to get hold of now a days.

Not as bright as the incandescent, but certainly not burning to the touch any more and doing a job! :)

Out of interest, what voltage and wattage bulb did you go for in the end? I think the brightness looks nice, but these things can look different in a photo.
 
From the listing:

12V warm white miniature MES LED bulb featuring a high luminous intensity and long lifespan, suitable for replacing filament lamps and backlighting applications.
  • Operating voltage: 4-24V
  • Brightness: 9,000mcd
  • Viewing angle: 30°
  • Forward current: 20mA
It's working fine enough in dark conditions. Still doing it's job. Little strange seeing the 'refresh' of the LED when so used to incandescent.
