Light pollution, a growing environmental concern, refers to excessive or obtrusive artificial light at night, which can disrupt ecosystems and affect human health.

The brightness of candles is significantly lower than that of most artificial lighting sources. A standard candle, typically with a flame diameter of about 2-3 cm, emits a relatively small amount of light. While the flame's color and intensity can vary depending on the type of wax and wick, as well as the burning conditions, a typical candle produces a warm, soft glow. This glow is much dimmer than the bright, focused light emitted by common artificial lighting fixtures like LEDs, fluorescent tubes, or incandescent bulbs.

In terms of lumens, a unit of measurement for light output, a standard candle generally produces around 10-20 lumens. For comparison, a typical LED light bulb can output 400-1000 lumens, and a fluorescent lamp can produce over 1000 lumens. This means that candles are far less intense in terms of light output, making them a much less significant contributor to light pollution.

Despite their lower intensity, candles can still contribute to light pollution in specific contexts. When used in large quantities or in areas with minimal natural light, the collective light output of multiple candles can become noticeable. For instance, a candlelit dinner or a room filled with candles can create a noticeable glow, especially in the absence of other artificial lighting. However, this is generally a controlled and intentional use of light, and the impact on the surrounding environment is minimal.

In contrast, artificial lighting sources are often designed to be highly efficient and bright, making them more susceptible to causing light pollution. Streetlights, building exterior lighting, and illuminated signs can contribute significantly to light trespass, sky glow, and glare, all of which are forms of light pollution. These artificial lights can disrupt the natural cycles of plants and animals, affecting their behavior and ecological balance.

In summary, while candles do emit light, their brightness is generally not a significant concern for light pollution. The soft glow of a candle is a far cry from the intense, focused light of artificial lighting sources. However, in specific contexts, the collective light output of multiple candles can become noticeable, and it is essential to be mindful of the impact of any lighting source on the surrounding environment and ecosystems.

Outdoor vs. Indoor: Does placing candles outdoors contribute more to light pollution than indoor use?
