There are many types of light bulbs on the market today, each with its own advantages and disadvantages. When it comes to choosing a light bulb that most closely resembles natural light, there are a few factors to consider.
The first is color temperature. Color temperature is measured in Kelvin (K) and indicates the overall tone of the light. For example, cool white light has a color temperature of around 4100K, while warm white light is typically around 2700K. Natural sunlight has a color temperature of around 5600K, so cool white bulbs come the closest to replicating that type of light.
The second factor is brightness. Brightness is measured in lumens (lm) and indicates how much light is emitted by the bulb. The higher the lumen rating, the brighter the bulb will be. Most LED bulbs on the market today have high lumen ratings, making them some of the brightest options available. However, they may not produce as much warmth as lower lumen bulbs like incandescents or halogens.
Finally, you'll want to consider beam angle when selecting a light bulb. Beam angle refers to how wide or narrow the beam of light emitted by the bulb is. Narrow beam angles create focused beams of light while wide beam angles produce more diffused lighting. Sunlight has a relatively wide beam angle, so bulbs with wider beam angles will come closest to replicating that type of lighting in your home or office space
