Eternaleds today introduced their new Hydrolux-4 LED lightbulb, which is the first LED bulb in the world to use liquid-cooling technology to give true 360 degree light like a regular light bulb. The Hydrolux-4 can lower your monthly electricity bill since it only consumes 4-Watts of electricity. Each lightbulb is rated for 35,000 hours of use, meanwhile the liquid inside is harmless paraffin oil that has been tested and certified safe to UL and ROHS standards. The Hydrolux-4 LED lightbulb is currently available in “warm white” and “daylight” flavors. Video after the jump.
