Eternaleds announced their new Hydrolux-4 LED lightbulb, the very first liquid-cooled bulb in the world. The bulbs are incredibly energy-efficient compared to either incandescent or CFL bulbs, and come with a price tag to match.
The bulbs, which cost $35 each (!), are rated for 35,000 hours of use and only consumes 4W of electricity (compared to a 25W incandescent), which means if you're afraid of the dark and run it 8 hours a day for an entire year, it'll only cost $1.75. It's fully dimmable and, unlike other LED lights, cool to the touch, thanks to the oh-so-hardcore liquid cooling. The bulbs come in "warm white" and "daylight" flavors, and are available now.
