This is a low cost, compact spectral lamp with power supply. The lamp is mounted inside a black protective tube standing up from the top of the power unit. By rotating the outer sleeve of the lamp cover, different shaped apertures can be selected.

Unlike the dull light available from Spectrum Tubes these tubes provide a bright and intense light used for optical work and for AA Spectrometry.<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />
