I bought a lamp online, when it arrived it had a three prong circular plug. Possibly an Indian plug? I bought a UK plug and when I went to swap it over there is no green earth wire. Could I use an Indian/UK adapter? The lamp is mostly metal and I have children so I'm concerned about possible shocks from the lamp. I'm not sure an electrician would be able to access the wiring to add an earth cable. Before I buy an new lamp I thought I'd ask, thanks.
