Kosnic presents this DD CFL lamp for the wall and ceiling lighting market. DD lamps are an excellent 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 crisp 4000K 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.
