Kosnic presents this DD CFL lamp for the wall and ceiling lighting market. DD lamps and their respective fittings are a great choice for lighting areas that need high output and sturdy casings such as hallways and public spaces. This 38W DD lamp provides an output equivalent to a 120W Incandescent lamp and produces a white 3500K output. The 4 Pin base can only be installed into a 38W rated fitting due to the positioning of the plastic connectors on the base. Please note that this lamp is not dimmable unless used with specialised control gear.
