The PET rigid stem light was developed for the B15d lamp and the special reflector lamps. Clean and simple design. The lamp is secured against unintentional disconnection.
Same design as PET however the stem length is only 50mm/2”
When using plug-in lights of a length of less than 100mm/4” in combination with surface-mount transformers please use reflector lamps with an aluminum coating. The heat from these lamps is directed forward, away from the fitting.
