That is fantastic. Can you tell me - how does it work ?
Do you screw it into a socket and use it as normal ? If there is load shedding - does it come on on its own or is there something that needs to be done first to come on ? Do you not have any stock of any of them at the mo ?

I see it does not say anything about a "internal battery" or "rechargeable" at all on the box ????
