Hmph.... Have a look at the purchase price of a nightlight,
(which comes with a spare bulb), versus the cost of buying
a replacement 7W bulb.... assuming a 7W can be found.

I now just strip all the photocell gubbins out, and feed
the bulb from a 1N4007 diode. This enormously extends the
bulb life and allows a higher wattage bulb in there, if
neccessary.

Well, a filament lamp of that power and voltage is just nuts.
Look for a tiny fluorescent one instead, such as this 3W one
which was a couple of quid IIRC from homebase...
