The Lamp Room

There's a chap who has a YouTube channel under the name 'Technology Connections' who has uploaded a number of quite interesting videos on some of the lighting technology either from the past, or in use today. Worth a watch in my opinion...

There are more besides these, just search his channel content. Some other non-lighting content that's quite interesting too!

Ah yes he has some great videos, and also points out a common mistake people make that always annoys me, electronic CFL's getting the blame for flicker that they never had!

Some great videos about air conditioning and refrigeration on there too.

Yeah, with the lighting, this guy has done the homework!

He certainly seems to know his subject well. Some of these are very detailed
