The phrase “voltage drop” isn’t a piece of complex jargon. You can take it at face value. Voltage drop can refer to the passage of current which results in the dropping of voltage in an electrical circuit. Such a reduction is common with LED light bulbs and can affect their performance. When you switch on LED lighting, the bulbs heat up. This increase in heat decreases the current flowing through the circuit. In other words, the voltage drops. The amount of this drop can vary b …
