- High up-front costs.
- Transformer compatibility.
- Potential color shift over lamp life.
- Performance standardization has not yet been streamlined.
- Overheating can cause reduced lamp life.
Are LED lights safe for human eyes?
LED plant lights with a lot of blue and UV diodes can be harmful to our eyes. The same goes for all-white lights that emit a cooler white light (5000 Kelvin and higher). The amount of harm an LED light can cause depends on the color and the intensity. Any powerful light can hurt our eyes if we stare directly at it.
