Carbon filament lamps have several disadvantages:
1. Inefficiency: They consume a lot of power and generate heat, making them less energy-efficient compared to modern lighting technologies like LEDs or fluorescent lamps.
2. Lifespan: Carbon filament bulbs have a shorter lifespan than other modern light sources.
3. Poor Color Rendering Index (CRI): They have a lower CRI, meaning they don't faithfully reproduce the colors of objects as compared to other lighting technologies.
4. Fragility: Carbon filament bulbs are more prone to breakage due to their delicate construction.
