emailmempt It depends where you are, items in the emails are priced in US dollars but when you view the item page, if you are logged in, it will display the price in your local currency not US dollars. Can be confusing if you currency is in Australian , New Zealand or Canadian dollars.

emailmempt It says 5000W but that is a blatant lie. A 2400W appliance will use 10A at 240V So 5000W at 240V would be 20.8A far in excess of any standard domestic plug except maybe a stove socket. Why can't they just tell the truth?

emailmempt You can save anything you want on, it movies, pictures and music.

emailmempt Yes you can see it printed on the sides of the stones in the picture. You can tell by the feel of them also.

emailmempt It says 5000W. A typical 240V 2.4Kw fan heater runs at 10A. Would you leave one of them running 24-7? I think you would most certainly notice an increase in your power bill and that is just at 2400W so imagine what 5000W at 240V drawing 20.8A will do to your wallet. But in all seriousness this light fitting can in no way be 5000W. It is more likely 150W to 200W. Not bad but still enough top cause a slight increase if you run it 24-7.
