T12 Ubend fluorescent tubes feature a U-shaped design with a 1.5-inch diameter. They provide bright, wide illumination and are often used in older fixtures in offices and industrial spaces. T12 Ubend tubes are reliable for specific lighting needs but are gradually being replaced by more efficient options. 

4100K (Cool White) 

This light emits a crisp, bright white tone that is cooler than neutral white but not overly harsh. It is commonly used in workspaces, garages, and healthcare settings, where clear visibility and focus are important. Its clean, professional appearance makes it ideal for areas requiring high attention to detail. 

5000K (Daylight)  

A bright, white light that closely mimics natural daylight, providing excellent color rendering and clarity. Ideal for areas where true-to-life color appearance is important, such as in art studios, kitchens, or task lighting. It also creates an energetic, awake atmosphere, making it ideal for areas where alertness is key. 

6500K (Daylight Blue) 

A cool, bluish light that mimics daylight in its purest form. Often used in areas that require high visibility and detail, such as photography studios, hospitals, or high-precision work areas. It promotes alertness and can even improve mood and concentration, though it may be too intense for home settings.
