How do different light sources compare in terms of brightness and color temperature?

Different light sources can vary significantly in brightness and color temperature. For example, incandescent bulbs typically emit a warm light with a color temperature around 2700K, while daylight LEDs can reach up to 6500K, providing a cooler, bluish light.

What about energy efficiency? How do they stack up?

Energy efficiency varies widely. LED lights are the most efficient, using about 75% less energy than incandescent bulbs. CFLs are also more efficient than incandescents but less so than LEDs.

Can you explain how color rendering index (CRI) affects light sources?

The Color Rendering Index (CRI) measures how accurately a light source displays colors compared to natural light. A CRI of 100 means colors appear as they would in natural sunlight. LEDs can have a CRI ranging from 80 to 98, while incandescents usually have a CRI close to 100.

Which light source is best for photography?

For photography, natural light is often preferred, but if using artificial sources, look for lights with a high CRI and adjustable color temperature to achieve the best results.
