The Spectral Lamp Power Supply is a compact and self contained instrument for operating spectral lamps, which are instruments that emit light at specific wavelengths based on the elements or compounds inside. They are commonly used in classrooms especially in spectroscopy experiments. It includes a Fixed Holder and No Sodium Lamp. 

The lamp can be easily rotated to select different shaped apertures using the outer sleeve of the cover and can be used with economical sodium, mercury, neon, and helium spectral lamps.
