World’s first liquid-cooled LED light bulb

Liquid-cooling has been around for quite sometime, with internal combustion engines, PCs and now light bulbs. LED light bulbs have many advantages over conventional bulbs, the use less energy and last quite a bit longer. One downfall to LED bulbs is that create a lot of heat and don’t give light 360-degrees around the bulb. A company called Eternaleds has created the world’s first LED light bulb that is liquid cooled, called the HydraLux-4 LED Bulb. The LED bulbs have paraffin oil in them that has undergone testing and has been certified as safe to UL and ROHS standards, so there is no safety issues if it is broken and leaks.
The LEB bulbs uses just 4W to put out as much light as a standard 25W incandescent bulb, they also last about 35 times longer. While it isn’t enough to light up a room, it would be more than enough for a desk lamp or accent lighting. And the longer lifespan of the bulb should make it more cost effective than traditional incandescent bulbs. They will be drop-in replacements for any standard E27 medium base sockets and will come in a “warm white” or a “day light” version. They’re a bit pricey at about $50 each, but should pay for themselves in the long run.
