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 …

These days, technology evolves fast. But even though we accept this, new products can still surprise us. The latest LED developments are no exception. Take organic light emitting diodes (OLED light bulbs), for example. These can give high quality images on monitors and TV screens. They also provide the illumination for low energy lighting panels. Organic compounds are the main component of OLED light bulbs. The compounds contain carbon, which appears in its purest form as either graphite or diam …

Before we consider exactly what constitutes a useful lumen, it’s worth considering the two different kinds of light beam, and the effect which you wish to achieve by using either of them. If a lamp features a beam angle which is wider than 90 degrees, it’s classed as wide angle as opposed to directional, and is therefore unsuitable for accented lighting like spotlights. Conversely, a beam of less than 90 degrees is considered directional and can be used for dramatic lighting in and a …
