Fire rated downlights and building regs

vantech

Hi,

What are everyone’s thoughts on this video about fire rated downlights and their necessity in 2 level domestic dwellings? 

JW has explained the reasons as to why they are apparently not required for certain installations, and this actually goes against what most manufacturers / wholesalers would tell you. 

YouTube video should be linked to this post.

Thoughts?

    However, there are some aluminium lamps that direct heat through the lens of the lamp and so need a smaller pocket of insulation to safely accommodate the fitting. Unfortunately there is no way of ensuring that bulbs are not interchanged and so cause potential future heat build-up problems if changed from one type to the other.

    I thought that Dichroic lamps (the 230V versions at least) has  GZ10 cap rather than a GU10 - the difference being the lack of a chamfer around the plastic base - so should only fit into holders that are intended to accept them.

    This is correct, one is 230v the other 12v. 

    You can however very easily swap the lamp holder by removing the transformer, maybe this is what they mean (as in, it’s very easy to change the lamp holder type).
