Proof, not promises.

A real-world mould test using white bread, a humid jar, and fourteen days.

The bread test is what we see in our home. The laboratory test is what we see under controlled conditions. Both shown here.

Bread, humid jar, fourteen days. One side used First Light every day. The other side did not. Same room. Same air. Different result.

Results will vary.

Why This Test

Mould is difficult to demonstrate honestly.

Laboratory tests are important, but they often feel abstract. Real environments are messy, uncontrolled, and imperfect. That is exactly where mould thrives.

So instead of starting with claims, we started with something familiar.

White bread rolls, left exposed to everyday indoor air. Observed over time.

One roll placed in an environment where First Light was present. One roll placed in an environment without First Light.

Nothing hidden. Nothing accelerated. Just comparison.

How this test was run

The test was conducted in a real indoor environment using materials mould commonly grows on. Conditions were intentionally simple so the outcome could be clearly observed.

What was controlled:

  • Same bread type
  • Same environment
  • Same exposure time
  • Same handling
  • Airflow variability
  • Ambient humidity fluctuations
  • Background microbial load

Those variables exist in real homes. We chose to keep them consistent.

What this shows

A visible difference in mould development under real-world conditions.

The oils spreading through the air over time.

A visible difference without laboratory framing.

Performance under conditions mould favours.

What this does not claim

Not a registered disinfectant. Not a remediation product.

This is not a medical claim.

This is not a regulatory pass or fail test.

Results will vary by environment.

How to read this result

This observation is not intended to stand alone.

It is one piece of evidence, alongside the laboratory test, formulation discipline, and real-world use over time.

We share it not to persuade, but to allow scrutiny.

Our Approach to Evidence

We believe products should earn trust quietly.

If something works, it should be visible without persuasion. If it doesn't, no amount of language can fix that.

This test is not designed to impress. It is designed to be seen.
