What is an incandescent light bulb?

An incandescent light bulb is a type of electric light bulb that produces light by heating a filament wire to a high temperature until it glows and emits visible light. In short, an incandescent bulb relies on electricity to heat a wire that generates light. They’re one of the earliest and most common types of electric light bulbs and are found in many households and workspaces alike. As opposed to a bright white light, incandescent bulbs produce a warm yellowish light, making them ideal for creating a gentle ambience in a room.

What is an LED light bulb?

An LED light bulb uses light-emitting diodes (LEDs) to produce light. They work by passing an electrical current through a semiconductor, causing the release of light and producing energy-efficient, long-lasting, and versatile lighting. Their energy efficiency makes them more environmentally friendly than alternatives, using significantly less energy while producing the same amount of light. The lifespan of an LED bulb is another reason why they’re so popular, typically lasting tens of thousands of hours, significantly more than alternative options.

What are lumens in light bulbs?

Lumens in light bulbs are a measure used to quantify the total amount of visible light from a light source. Essentially, they’re a way of knowing how bright a lamp is without having to turn it on! You’ll understand the brightness level of a light bulb by the following logic: the higher the lumen value, the brighter the light output. Opt for a high-lumen bulb for bright lighting, ideal for kitchens and bathrooms, or choose a low-lumen bulb for some mood-setting lighting, perfect for bedrooms and living spaces.

What is the lowest watt light bulb?

LED (light-emitting diode) bulbs are typically the lowest-watt light bulb in the market. Jam-packed with highly efficient technology, they’re able to produce more light output for a given wattage compared to traditional bulbs. The lowest wattage you’ll find will be 1W (sometimes slightly lower) while still providing a decent amount of light output. As a rule of thumb, check out the bulb's lumens for a more accurate measure of their brightness.
