4 Reasons to choose Kosmos over a 24V central battery system

In many specifications, projects, and technical requirements, the traditional 24V Central Battery solution is still commonly prescribed for emergency lighting centralisation. It is often an automatic choice, driven more by habit than by logical or technical evaluation.

But let’s pause for a moment: does it really make sense to continue down this path today, when Kosmos exists?

The answer is simple: no. And the reasons are numerous, concrete, and measurable.

1. Kosmos costs less. Much less.

A 24V Central Battery system requires larger cable cross-sections to compensate for voltage drop inherent to low-voltage systems. This results in higher material costs and slower, more complex installations. For the same project, Kosmos can reduce overall system costs by up to 50%, making it significantly more competitive.

2. Maintenance? Almost forget about it.

Lead-acid batteries used in Central Battery systems require frequent maintenance and periodic replacement. Kosmos, on the other hand, uses lithium batteries with a 5-year warranty: safer, longer-lasting, and far more stable over time. In simple terms: fewer interventions, lower costs, greater efficiency.

3. Simplified installation, smarter system.

Kosmos is the first loop-supervised system with integrated isolators on each luminaire. This means that in the event of a fault, the bus continues to operate — no more systems taken offline because of a single defective point. Moreover, Kosmos precisely identifies the faulty luminaire, allowing fast, accurate, and targeted maintenance.

4. Advanced supervision and true operational continuity.

System continuity is not a minor detail. In critical environments — hospitals, schools, companies, and public institutions — knowing that emergency lighting remains operational even in the event of a partial fault makes all the difference.

If you are a designer, installer, or technical manager, you know how crucial reliability, cost efficiency, and ease of management really are.

So ask yourself: why continue to specify or install 24V Central Battery systems, when Kosmos offers a more advanced, more cost-effective, more intelligent, and safer solution?

The future of emergency lighting is already here. Its name is Kosmos.
