To make the right choice of light bulbs, it is important to understand the concept of lumens due to changes in lighting regulations and technologies. However, there are other important facts to check on the label before making a purchase, such as:

1. Estimated yearly cost of energy: The label should indicate the estimated yearly cost of energy for the bulb. This information can help consumers choose energy-efficient bulbs that can help save money on energy bills.

2. Lifespan of the product: The label should also indicate the estimated lifespan of the product. This information can help consumers choose bulbs that have a longer lifespan and may be more cost-effective in the long run.

3. Light appearance: The label should indicate the light appearance of the bulb, which ranges from warm to cool, as per the correlated colour temperature (CCT). Warm light appears more yellow or orange, while cool light appears more blue or white. This information can help consumers choose bulbs that provide the desired level of light appearance for their needs.

By checking these facts on the label before making a purchase, consumers can make informed decisions when selecting light bulbs. This can help ensure that they choose bulbs that are energy-efficient, have a long lifespan, and provide the desired level of light appearance for their needs.
