Liquid cooled LED lamp

The Eternaleds HydraLux-4 LED Bulb is the first LED bulb in the world to use liquid-cooling technology to give true 360 degree light like a regular light bulb! It uses 4W to put out as much light as a 25W standard "A-Shape" incandescent bulb while lasting 35x longer. It's a drop-in replacement that can instantly replace any indoor bulb that uses a standard E27 medium base socket.
 
This LED bulb is great for applications such as: desk lamps, sconces or anywhere you'd use a 25W incandescent bulb. Not to worry, if you drop/break it - the liquid inside is harmless paraffin oil that has been tested and certified safe to UL and ROHS standards.
