Now here’s a bright idea (sorry, we just had to). Samsung’s newly available LED light bulbs should swiftly put their old-school bulb-producing competitors out of business, and here’s why: not only do they light up a room using a fraction of the power of traditional bulbs, but they’re rated for 40 000 hours – or 27 years with typical usage of 4 hours a day.

Some models of said light bulb are brightness-adjustable to boot. Check out full specs at SlashGear or head to your local Lowe’s to pick up a pack – 20-60$.
