Important aspects when choosing light sources:

1. **Light Quality**:

   - **Light Color**: Different bulbs offer different color temperatures (warm, neutral, cold). Choosing the right color affects visual comfort and mood. Tungsten bulbs usually emit a warm, pleasant light that is more natural and less tiring for the eyes than cold LED light.

   - **Color Rendering Index (CRI)**: High-quality bulbs have a higher CRI, which means better color reproduction. Tungsten bulbs have a high CRI, while cheaper LEDs may have a lower CRI, which affects visual quality and aesthetics.

2. **Comfort and Health**:

   - **Flicker**: Cheaper LEDs can flicker, which can cause eye strain and headaches. Tungsten bulbs don't have this problem, which makes them more comfortable to use.

   - **Blue Light**: LEDs, especially the cheaper ones, emit more blue light, which can disrupt sleep patterns and affect eye health. Tungsten bulbs emit less blue light, which is beneficial for eye health and sleep quality.

3. **Longevity and Cost**:

   - **Lifespan**: LEDs have a longer lifespan than tungsten bulbs, but cheaper models may have a shorter lifespan and a higher failure rate. Low-quality LEDs may lead to more frequent replacement.

   - **Cost**: While LEDs are energy efficient and have a longer lifespan, cheaper LEDs can have higher hidden costs due to more frequent replacement, flicker and lower light quality.

4. **Impact on the Environment**:

   - **Ecology**: LEDs are more energy efficient and longer lasting than traditional bulbs, which is good for the environment. However, the lower quality of LEDs can lead to more waste if they break down frequently.

### Arguments against cheaper LEDs compared to tungsten bulbs:

1. **Light Quality**: Cheap LEDs often have a lower CRI, which means poorer color reproduction. This can lead to a less pleasant and natural lighting compared to the warm, natural light of tungsten bulbs.

2. **Comfort**: Cheaper LEDs can flicker or emit a disproportionate amount of blue light, leading to eye fatigue and sleep problems. Tungsten bulbs are more stable in terms of light quality and are gentler on the eyes.

3. **Longevity and Hidden Costs**: While LEDs are typically more energy efficient, cheaper models can have a shorter lifespan and higher failure rates, which can lead to higher long-term costs when you factor in frequent replacements.

In conclusion, although LEDs offer many benefits, such as energy savings and longer life, cheaper models can have serious drawbacks that affect eye comfort and health. Tungsten bulbs, despite lower energy efficiency, can provide better light quality, greater comfort and less eye fatigue. It is worth investing in high-quality light sources to ensure long-term comfort and health.
