G4 vs prior generations
The G4 delivers faster disinfection cycle times, improved UV lamp output geometry for better room coverage, and enhanced Xenex facility management software for tracking cycles, compliance reporting, and integration with hospital environmental services workflow systems.
How it compares
G4 competes with UVD Robots UVD-C (autonomous navigation vs LightStrike's manual positioning), Tru-D SmartUVC, and emerging UV-C LED autonomous platforms. The G4's pulsed xenon approach remains Xenex's core technical differentiation versus LED-based competitors.
Limitations
- Manual repositioning still required between room positions
- Xenon lamp replacement operating cost
- Room must be vacated during cycle
- Line-of-sight UV limitation on deeply shadowed surfaces
FAQ
What is different about the G4 versus earlier LightStrike models?
The G4 delivers faster cycle times, improved UV lamp output geometry for better room coverage, and enhanced facility management software for cycle tracking and compliance reporting. The core pulsed xenon technology is retained.
Is the G4 autonomous like the UVD Robots system?
No. LightStrike G4 is manually positioned by environmental services staff between room positions. The UV pulsing cycle is automated, but the robot does not autonomously navigate between positions.
How does the G4 integrate with hospital workflows?
Xenex provides facility management software that integrates with hospital environmental services systems for scheduling, cycle documentation, and compliance reporting for infection control audits.
Can hospitals upgrade from older LightStrike models to G4?
Contact Xenex directly for upgrade pathway options from earlier LightStrike generations to the G4.
