About Lumitra — Low-Voltage Contractor Built for What's Next
Who We Are
Lumitra is a commercial low-voltage contractor based in San Antonio, Texas. We work on the infrastructure that powers modern buildings — structured cabling, network rooms, smart building readiness — and we deliver the documentation to back it all up.
We started Lumitra because we kept seeing the same problems on job sites: low-voltage work that was technically installed but poorly documented, network rooms that were a nightmare to manage, and buildings that weren't ready for the connected systems their owners wanted to add.
We decided to do it differently.
Our Approach
Think Ahead
We coordinate with your schedule, not the other way around. We're on site when we're supposed to be, we flag issues early, and we don't hold up your CO with last-minute problems.
Document Everything
Our submittals are complete and our RFIs are clear and specific. We don't send vague questions — we come with options and recommendations.
Be Easy to Work With
Data cabling, network rooms, AV rough-in, access control, security cabling — one contract, one crew. No coordinating between three different subs for low-voltage work.
Where We Work
We're headquartered in San Antonio and serve commercial projects across Austin, Central Texas, and beyond. If you have a project, reach out — we'll tell you quickly whether it's a fit.
