Yes, artificial light can be used for photosynthesis, but how efficient that light is depends on the source. Every light source has its own unique mixture of wavelengths.
Some artificial light sources are made up of a lot of wavelengths that are not much used by plants (like green and yellow), meaning a lot of light is wasted. They can still promote photosynthesis (in fact, the sun contains a lot of yellow light), but light that contains more red and blue wavelengths is more efficient.
That’s because the main wavelengths used by plants are red and blue light. as long as the light source you are using has both, it can grow plants.
You might be thinking that your light source gives off a white light. White light actually contains all colors, so it does contain red and blue. Warmer white light (color temperatures around 2700K to 3500K) contains more red and cooler white light (4500K to 6500K) contains more blue.

Understanding Photosynthesis
Photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen. This process primarily relies on the presence of light, usually sunlight.
Effect of Torch Light on Photosynthesis
- Light Spectrum:
- Plants primarily use red and blue light for photosynthesis. Most torch lights emit light in a spectrum that may not be optimal for plant growth.
- Light Intensity:
- Torch lights generally provide lower light intensity compared to sunlight. Insufficient light intensity can lead to reduced photosynthesis rates, limiting the plant's ability to produce energy.
Photosynthesis in Darkness
- Absence of Sunlight:
- In a completely dark environment, photosynthesis cannot occur, regardless of the light source. While torch light may facilitate some photosynthesis, it would be significantly less effective than natural sunlight.
- Duration of Light Exposure:
- Continuous exposure to torch light may not sustain the plant's energy needs. Plants require a certain duration of light each day to thrive.
Conclusion
- Feasibility:
- While a plant may perform some photosynthesis under torch light, it is not sufficient for optimal growth.
- To ensure healthy plant growth, natural sunlight or specialized grow lights designed for photosynthesis should be used.
In summary, while torch light can provide some energy for photosynthesis, it cannot fully substitute for sunlight. For healthy plant growth, proper light conditions are essential.
