There are 1001 simple circuits for blinking (LED) lights but I have found no comparison between the various types of circuits and their consumption of current. This light will be mounted on my store hut to show an active alarm. It needs to be bright in day light with a blink rate of once every 10 sec. It needs to run for ever off a battery, therefore the lowest consumption of current is of a high priority. Any ideas will be welcomed.

To be visible in daylight the led needs 20mA for say 100ms. So flashing every 10 seconds it will take an average of 200uA. An alternative is to use a 'flag', this is powered once, to show it when necessary.
