INSTRUCTIONS FOR USE:
This clever energy saving light bulb incorporates an electric light sensor that automatically switches the bulb on when it gets dark (dusk) and switches it off in the morning at first light (dawn).
WALL LIGHTS:- The light sensor must face outwards towards the light source.
When fitting or turning bulbs always hold by the plastic base (if possible).
For screw type bulbs (ES) simply tighten fully and then unscrew a little until the sensor faces the light.
NOTES: 1/. The light levels required to switch the bulb off and on are factory preset and cannot be changed.
2/. There is a built in delay before darkness turns the bulb on. This is to prevent the bulb from turning off and on constantly .To test the bulbs in daylight it is necessary to totally cover the light with a dark cloth. Simply covering the sensor will not turn the bulb on.
