## Core Technology: LightStrike™ Robots

### What Makes Xenex Unique
Xenex's patented Pulsed Xenon UV technology is fundamentally different from other microbial reduction UV systems:

1. **Pulsed Xenon vs. Mercury UV**: 
   - Xenex uses Xenon, an environmentally friendly noble gas  to generate broad spectrum UV light instead of toxic mercury
   - Produces broad-spectrum UV light (240-315 nm) vs. single wavelength (253.7 nm) from mercury lamps - broad spectrum UV light is more efficient at inactivating pathogens
   - No warm-up or cool-down period required (mercury lamps need this)
   - Does not damage surfaces like continuous mercury UVC

2. **Speed and Efficiency**:
   - Achieve Whole Room Microbial Reduction with 3 cycles of LightStrike+ UV in a typical patient room with a bathroom.
   - Effective against even the most difficult pathogens, like C. difficile or C. diff
   - LightStrike+ empowers EVS teams to address the unavoidable limitations of manual cleaning.
   - No room mapping required
- UV technology like LightStrike+ shouldn't be an additive to a hospital's cleaning and disinfection process; it should be an integrated part of an effective cleaning and disinfection process.

### How It Works
1. Manual cleaning completed first
2. Robot positioned in room
3. Emits intense pulses of germicidal UV light
4. UV light absorbed by pathogens, damaging their DNA/RNA
5. Multiple positions used to eliminate shadows and to flip commonly touched items
6. Entire process monitored and tracked
7. Inactivates persistent germs on treated surfaces that survive manual cleaning
