Almost a month ago I started trying to reverse engineer an inexpensive LED color changing light bulb. With your help I’ve mapped out the circuit, and taken control of the bulb. But there’s still a few ...

In a finding that runs counter to a common assumption in physics, researchers ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away. In a ...

Despite plenty of technical advances, incandescent lightbulbs still rule when it comes to color and quality of light. The trouble is, they don’t always last so long, and they waste almost all of their ...

The SlimStyle’s radical design allows for continuous operation without the need for aluminum heat sinks, one of the major cost drivers of LED bulbs. Philips At the beginning of 2014, the incandescent ...

Vintage-style LED smart bulbs have been a thing for a while, but I haven’t seen one quite like this new one from Savant’s GE Lighting division. The all-new Cync Clear Full Color Direct Connect A19 ...

I went to the last monthly meeting of Sector 67, a hackerspace in Madison, WI. One of the things shown off was a color changing LED light bulb that Menards was clearing out for $1.99. Inside there’s ...
