    There for use outdoors lighting an arena, prob have to use SWA so,
    maybe 2.5 sq. 3 are close to the board and the other 3 will be 20 - 30 metres away

    Would 2.5 sq NYMJ be safe to use, it would save me a good bit of money all right, I might run it through ducting instead of using SWA and loop the lights through seperate junction boxes
