2 Rooms, 1 Light
We’re all about saving electricity whenever you can. However, there’s a pretty fine line between being conscious about electricity consumption living frugally to a fault, and this homeowner is flirting with it. What we have here is a fluorescent tube going through a wall and semi-illuminating two rooms.

Is this a genius move or not? In our humble opinion, it might be, especially since one fluorescent tube can be more than enough to light up two rooms. But if you really want your room to shine without spending a ton on electricity, just get LEDs. They’re super-bright, don’t produce a ton of heat, and a single bulb can last upwards of five years.
