So I've purchased a Maplins power monitor plug to work out which electrical devices are costing how much. See

For those that haven't seen this before, you just plug this device into a three-pin socket and then whatever you want to test into that. It starts to count the number of kWh being used, straight away.So I plug in a table lamp with a 60W bulb. Anyway, after 4 hrs the device has measured 0.08kWh (approximately 0.02kWh per hr). So if I'm correct in thinking, after 4 hours the table lamp has only used 80W in total - but its a 60W bulb so shouldn't it be a lot more than that - I don't geddit?
Many thanks if anyone can correct me.
