Thanks Sleah, Thats actually really helpful seeing it phrased that way regarding the sockets. Given its 4 of them (lights), this would total 4000w. I assume that means one light would need another dimmer which would need to be plugged into another socket else where in the hall? If only for my own knowledge, I'd love to know if I've understood the above correctly. Whilst I'll still give it some more thought, the more I learn the LDS seem like the easier option. I'm just not sure if they will light the ring at all. If I purchase the LDS I can try them for around the ring and if it doesn't work I'd at least have plenty of lighting to make our entrance area look flashy instead so all would not be lost. Thanks so much for taking the time to reply and helping my education on this. I did see someone light a ring using just led security flood lights, it looked terrible from a lighting perspective but probably still created more atmosphere than sports hall lights. I'm just hoping to do something a little less glarey. It could easily be an issue. You have a maximum of 13A from a standard UK socket, and you can only connect a dimmer to one plug, so a maximum of 3.1KW per dimmer, not per channel. That's a maximum of 3x1000W or 4x650W theatre halogens per 13A socket. You'll soon be running round looking for 13A outlets! Then there will be a maximum the circuit can supply. 3x13A sockets fully loaded takes you to the maximum many circuits can supply. To avoid any potential problems of not enough power, stick with LED.
