This is my new homemade HPS 100W fixture. I made this because of my chemistry class: The teacher wants to teach us the reactions of some elements and she asked each student to bring the next week a chemical reaction. What better than an electric discharge on mercury and sodium? So I searched throughout my collection and found this ISB ballast and the HPS Osram 100W HPS, then I put everything together in a wood board and my project was finished :).
