You know how we all used to have those ‘ye olde incandescent globes that were really inefficient and didn’t last very long.... and now we all have compact fluorescents because they’re much more efficient and last for ages.... and us changing our light globes will save the planet (sorry, please don’t go there (a climate change debate) in this thread, go start another thread somewhere else ). Well, because they last so long, we don’t have to change them as often (yeah derr) so we don’t have to get up there and go near our light fittings as often.... so the bugs have much longer to accumulate.

That’s all.
