Firstly, the statement that "the closer you are, the more light you receive" is generally accurate for artificial light sources, including grow lights. However, the effectiveness of grow lights is not solely determined by proximity; factors such as the type of light (e.g., LED spectrum), intensity, and duration of exposure also play crucial roles in plant growth. While it's true that grow LEDs often have many more diodes than standard bulbs, it's important to consider the specific light spectrum they provide, as different plants may require different wavelengths for optimal growth.
Secondly, the personal experience shared about using four 5W LED bulbs to successfully grow a Ficus suggests that standard LED bulbs can be effective for certain houseplants. However, it's worth noting that different plants have varying light requirements. While a Ficus may thrive under such conditions, other plants might need more intense lighting or specific spectrums offered by dedicated grow lights to achieve similar results. Therefore, while the advice is valid for some scenarios, it may not universally apply to all plant types and lighting situations.
