It uses our super power 9.8" long custom made Heimann borosilicate glass xenon strobe tube and four powerful photoflash capacitors that drive it.

Operates from 120VAC and the PC board is 5 1/8" x 11". Overall size of completed strobe is 7" high x 13" wide x 2"deep. Complete with all parts, PC Board, unassembled enclosure and instructions. Skill Level 2. Please do not attempt to build this kit if you do not know AC safety precautions.
