2d Fluorescent Tubes

These light bulbs are called "2D light bulbs" due to their shape, resembling two letter Ds, leading them to be commonly referred to as "double D bulbs." Their compact design makes them ideal for shorter fixtures that cannot accommodate longer-shaped bulbs. As a result, numerous commercial properties have embraced 2D bulbs for ceiling fittings. These 2D lamps come in various cap fittings, catering to different fixtures and offering a wide range of options suitable for various applications.
