I recently closed another thread of yours with a warning that ill-considered thread titles are likely to lead to problems; and here you are with another one - posted in the wrong forum, too.
Even a brief look through the forums will lead you to plenty of useful discussion about incandescent lighting, with experienced members explaining why it suits their particular puposes.
This thread title of yours is utterly ridiculous, and you are warned that further provocative posts of this nature may well result in you being labelled a troll, and your posting privileges here revoked.
The thread is closed.
