Apparently the owner of the house thought he should live like a rich and so he installed a roof lamp with those artsy lamp shades in the living room. It looks nice but those artsy glassy lamp shades decrease the energy efficiency of the lamp dramatically. The lamp has six light bulbs, each rated at 60W (so it's a f**king 360W!), but the living room still looked dark at night. This must be one of the most ridiculous things I've seen - you use 360W and you still can't light up a <150 sq. ft. living room properly.
So I bought a floor lamp from Hung Hom, with energy-saving fluorescent bulbs. Another $600+ spent. Moving it from Hung Hom to Tai Po Tsai was NOT fun.
