Instead of simply replacing the outdated bulb, we decided to build a small dark detecting circuit with 2 yellow LEDs based on this Evil Mad Scientist Laboratories design. After successfully ...

There’s more to an LED bulb than just the LEDs. Outlets in our homes are actually fairly dirty sources of AC power. LEDs want clean, constant-current DC sources, so circuits inside the bulbs ...

The patented topology of FL7732 enables the most simplified circuit design, especially for LED lighting applications. By using a single-stage topology with primary-side regulation, an LED lighting ...

That means inside every LED bulb are tiny circuit components — and their soldered contact points — which are far more vulnerable than the diode itself. The Lighting Research Center of the Rensselaer ...

Our experts are rounding up the select few that are actually worth it. We’ve added Aqara’s LED Bulb T2 to What to look forward to. Smart LED bulbs provide a near-instant way to transform the ...

In a series circuit, the current passes from the power ... Next in line are the LED light bulbs. They're fed into the machine and tested for positive or negative charges. Then, the metal ends ...
