Liquid-Filled LED Bulbs: 360 Degree Light

September 13, 2009

I’ve been testing a new LED bulb called the HydraLux. These unique bulbs are filled with a clear liquid coolant (a non-toxic paraffin oil). Other LED bulbs use large metal fins or fans for cooling purposes. The advantage of using a liquid coolant is that the LED bulb can produce 360° light like a regular [...]

New LED Light Bulbs Can Replace 100W Incandescents

November 30, 2008

I recently had the chance to test two state-of-the-art LED light bulbs from EarthLED. LED bulbs have many advantages over incandescents and compact fluorescent: they use very little power, they last 10 years or more, and they contain no hazardous substances. They are also tough: they can be dropped and turned off and on repeated [...]

Motion-Sensing LED Lights: A Review

July 30, 2008

Motion-sensing LED lights — these lights are perhaps the most efficient lighting devices available today. They switch on whenever their infra-red sensors detect movement in a room — such as when someone begins to walk down a dark hallway. I’ve been testing them in my own home, and I’ve found them to be effective and [...]

OLEDs Printed Like Newspaper: World’s First Demonstration

March 11, 2008

OLEDs are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. They’re so thin, that they could be applied to rooms as a type of wall paper to glow at the touch of a finger or when someone enters the room. Like LEDs they produce light very efficiently. But [...]
