I'm a bit confused about using the bit of white heat resistant flex for downlights. Do we really need it on fire rated downlights? Isn't it just an extra unnessasary connection? Why not take the 1.5 standard T&E straight from the Hager (or similar) junction box to light? I'm still trying to understand the reasoning for the flex on fire rated downlights. What regs are we not meeting if we don't use the flex?
