GSS 0 Report post Posted December 28, 2007 Hi,I was told by my contractor's electrician, that only certain type of lights are approved for SP testing certification. The rest have to be fitted with an extra "thing", called ceiling roof or something, I could never make it out how he pronounced it.Anyway, hope any of you guys who have opted for SP testing can shed some light on this.Thanks.
