How to Choose T9 Circular Fluorescent Bulb

When selecting a T9 circular fluorescent bulb, the following factors should be considered:

• Color temperature

The color temperature of a circular fluorescent tube light is a crucial factor. It is measured in Kelvin (K). Typically, the color temperature of bulbs ranges between 2700K and 6500K. 2700K bulbs emit a yellowish light, which is warm. On the other hand, 6500K lights are blue and cool. 4000K and 5000K are considered neutral whites. Individuals should choose the color temperature that meets their needs.

• Color rendering

Circular tubes with a high CRI should be selected. A CRI above 80 is recommended because it allows colors to appear as they would in natural light. Choosing a bulb with a high CRI helps to prevent color distortion and ensures that colors look as they should in natural light. It is important to choose a CRI of at least 80 when selecting lamps for areas where color is essential, such as art galleries or restaurants.
