Ultra Violet Irradiation Reactor
6600 uW for 99% deac-va-on of E.coli
Peak effective wavelength of 265 nm discovered by Gates and isolated to 253.7 by Ehrismann and Noethling in 1932.

The Plan
41
Modernizing is really inexpensive and relatively fast to perform
The ROI is within the bulb warranty
Risk is low, gain is high
Purchase sample bulbs from Chinese Suppliers (3-4) and redo what I did with Uli with different
light fixtures
Test for quality and
performance
Order and replace old bulbs with new LEDs

Thoughts...
42
• Point lights towards the foot path, not the grass
• Optimize system for locating and changing broken lamps
• Use Mapbox to track bulb lifetime
• Use Mapbox to track changes (if no other system is in use)

Danke Schön
43
I am extremely grateful for this opportunity to learn and hopefully make an impact on both the Facility Management Unit and ALL of campus Westend.I’ve met several students from this campus and even people wanting to study here and everyone shows interest and support for my project.

Dirk Seitz for getting the project goingMilan Bosnjak for SAUTER & KNX Dieter Dreher for technical drawings and bulb informationRainer Born for LED lamps and toolsUli Ackerman guidance and support for installation of 14 LED lampsSteffi Lebedew for the DienstfahradNadja Fabel for making me speak a little GermanUwe Brede for interesting conversations and tours of the campus.Christoph Denecke & Detlef Wittwer for the initial/outline of the project at Campus Westend
+ Everyone ElseSaaba for keeping my office neat :)
...also Super Bonus Double Thanks to Christoph Denecke for all his help and advice throughout the project (making introductions, translating everything, guiding & clarifying my questions and showing me around the campus and Frankfurt.- if this project is a success it is because of your kindness!
