I quite agree 7 watts is to high but most of the night-lights being sold in the UK are a 7 Watt filament bulb so when you take into account the extra £2.00 worth of energy they use every year plus the bulbs only last any thing from 6-12 months they are not so cheap. There is also another consideration, child safety; filament bulbs may be fine on the ceiling, on a table lamp but at skirting board level , in the play zone, they are an electrocution risk to children as they are so badly manufactutred the protectivecover over the bulb is very easily broken leaving a bare 240 volt bulb.
