Lumetallix was developed to solve the biggest problems with traditional swab tests: false positives, unclear results, and limited sensitivity.

Swab tests have their place—but Lumetallix was designed to offer clearer results, better performance on complex surfaces, and fewer testing errors.

Lumetallix was invented by a team of chemists and engineers in the Netherlands, with science, safety, and simplicity at the forefront. It was developed to solve a real-world problem: giving everyday people a reliable way to detect lead without sending samples to a lab.

At the core of Lumetallix is a patented chemical process. When the reagent touches lead, it forms a special crystal structure called a perovskite, which fluoresces bright green under a 365nm UV light. It's clear, visible, and hard to misread.

Because of its success, Lumetallix has unfortunately been copied and counterfeited. Some products claim to offer similar results but use unreliable chemistry or generic UV flashlights that don't trigger the reaction properly.

To ensure you're getting the real thing, always buy Lumetallix from authorized sellers or direct through official distribution in the U.S.—like right here on our site.

If you're seeing green fluorescence before applying the Lumetallix reagent, you're observing something that naturally glows under UV light. This is not a lead reaction.

Common causes of pre-spray fluorescence include:

• Laundry detergent or optical brighteners
• Certain glues or adhesives
• Cleaning products
• Inks or dyes
• Fluorescent dust or paper fibers

These materials can glow under blacklight but do not indicate the presence of lead.

The Lumetallix test works only when the reagent is sprayed. If lead is present, the reagent reacts to form a perovskite crystal that glows bright green under UV light as you're spraying. This glow appears only if lead is detected.

If you see green without spraying the reagent, it's not a positive test for lead.

The UV flashlight in the Lumetallix kit—called the LeadLight—is a 365nm long-wave ultraviolet (UV-A) light, specially designed for accurate lead detection.

Unlike typical blacklights or off-the-shelf UV flashlights, the LeadLight delivers a precisely tuned and consistent UV output. This wavelength is ideal for activating the Lumetallix reagent, allowing it to fluoresce bright green when it reacts with lead.

Developed by a specialist team in the Netherlands, the LeadLight's quality and reliability ensure that your test results are driven by chemistry—not guesswork or weak lighting.

Lumetallix is safe for home use when used as directed, even in households with children and pets.

The reagent contains isopropyl alcohol, which helps deliver consistent test results and dries quickly. While it's not highly hazardous, it should be treated like any common household chemical:

• Avoid contact with eyes, mouth, or prolonged skin exposure
• Keep away from open flames or high heat (isopropyl alcohol is flammable)
• Store out of reach of children and pets
• Test in a well-ventilated area

After testing, simply wipe the area clean with a damp cloth. Always wash your hands after handling the reagent or testing suspected lead surfaces.

The Lumetallix test is generally safe for most solid surfaces, but caution is advised.

The reagent contains isopropyl alcohol, which can damage or dull:

• Certain varnishes and shellac finishes
• Some clear plastics like acrylic (e.g., Plexiglas)
• Painted surfaces with delicate or deteriorated coatings
• Softwood furniture with older finishes

If you're unsure about a surface, test a small, hidden area first. On most modern painted walls, sealed wood, tile, or metal, the test won't leave a mark and dries quickly.

To clean up, just wipe with a damp cloth. Always wash hands after testing.

Yes, Lumetallix can be used to test fabrics for surface lead—especially printed designs, painted logos, or decorative elements like beads or buttons. This can be helpful for parents concerned about lead in fast-fashion clothing or accessories.

However, since the reagent contains isopropyl alcohol, we recommend testing an inconspicuous area of the fabric first. Isopropyl alcohol can cause fading, discoloration, or damage to delicate materials, especially:

• Synthetic blends
• Varnished or painted decorations
• Certain dyes or screen-printed graphics

To test:

1. Choose a hidden corner or seam.
2. Shine the UV light first—some inks fluoresce on their own.
3. Lightly spray the reagent and observe under the UV light for any green fluorescence as you're spraying.

If you see a bright green reaction, that may indicate the presence of lead-based pigments or coatings.

A positive result with Lumetallix is easy to spot: as you spray the reagent and shine the included UV LeadLight, any lead present will cause the surface to glow bright green while you're spraying.

That green glow means the reagent has reacted with lead to form a perovskite crystal, which fluoresces under the 365nm UV light.

Here's a quick guide:

• ✅ Positive result: Bright green glow appears during or immediately after spraying
• ❌ Negative result: No color change under UV light after spraying
• ⚠️ Pre-spray glow: If you see green before spraying, that's just fluorescence—likely from detergent, dust, adhesives, or other non-lead substances

If you're unsure about what you're seeing, you can always test again or reach out for help interpreting your results.

Yes, Lumetallix can be used on a wide range of surfaces, including:

• Painted wood and drywall
• Metal fixtures and pipes
• Windowsills, baseboards, and doors
• Toys, furniture, and household items

However, there are a few surface considerations to keep in mind:

• Glossy or clear-coated finishes (like varnish) may be affected by the isopropyl alcohol in the reagent—test in a hidden spot first.
• Porous surfaces (like unsealed wood or stone) may absorb the reagent and be harder to clean afterward.
• Plastic items—especially clear or soft plastics—can sometimes react to alcohol, so spot test before spraying widely.

For best results, spray onto a clean, dry surface, shine the included UV light, and watch for green fluorescence while spraying.

Yes—Lumetallix can be used on both indoor and outdoor surfaces, as long as the area is clean, dry, and not exposed to rain or heavy moisture during testing.

Keep in mind:

• Dry conditions are important. If the surface is wet, the reagent may dilute or wash away before reacting.
• Rough or weathered surfaces (like peeling exterior paint or oxidized metal) may make it harder to get clear results. Try testing a smoother or more sheltered area nearby.
• If you're testing exterior areas like porch railings, siding, or window trim, it's best to do so during dry weather and out of direct sunlight, if possible.

After testing, simply wipe the area clean with a damp cloth once results are observed.

If Lumetallix shows a bright green glow while spraying, that means the reagent has reacted with lead—indicating a positive result.

Here's what to do next:

1. Stop disturbing the area. Avoid sanding, scraping, or cleaning the surface, as this can release hazardous lead dust.
2. Wash your hands and keep children and pets away from the tested area.
3. Document the location. Take photos or notes for your own records or if you plan to consult a professional.
4. Decide on next steps. Depending on where the lead was found (e.g., windowsill, toy, door), you can:Seal or repaint using lead-safe practicesRemove or discard the item if it's small and non-essentialContact a certified lead abatement professional for larger or high-risk areas
5. Keep testing. It's common to find more than one source, especially in older homes or buildings.

Lumetallix is engineered for exceptional sensitivity and specificity in detecting lead on surfaces. The reagent reacts exclusively with lead to form a photoluminescent perovskite crystal, emitting a bright green glow under the included 365nm UV LeadLight.

Key performance highlights:

• Detection threshold: As low as 1 nanogram per square millimeter (ng/mm²) visible to the naked eye, and down to 50 picograms per mm² when using digital imaging techniques.
• Selectivity: The reagent is highly selective for lead, showing no false positives across tests on over 50 different materials, including those containing metals like tin, copper, and aluminum.
• Sensitivity in paint: Studies indicate a detection limit of approximately 500 parts per million (ppm) of lead in paint, with a sensitivity of 95% and selectivity of 94% compared to standard analytical methods.

This level of accuracy allows Lumetallix to detect even trace amounts of lead on various surfaces, providing immediate and reliable results.

Each Lumetallix Instant Lead Detection Kit includes enough reagent for approximately 400 to 500 tests.

In addition to the spray bottle, the kit includes a dropper bottle that lets you apply the reagent more precisely—one drop at a time. This is ideal for small items or targeted testing and helps stretch the total number of tests closer to the 500 mark when used carefully.

Whether you're testing large surfaces or tiny details, the kit is designed to give you a lot of coverage with minimal waste.

It depends on the material being tested and how the lead is present.

For some objects—especially painted surfaces—the green photoluminescence from a positive reaction can remain visible for days or even longer under UV light. Other materials, like certain plastics or metals, may show a glow that fades after a few minutes.

Water exposure can break down the light-emitting perovskite crystal and stop the glow. But if the crystal is encapsulated or protected by the surface material, it can remain stable and glowing.

In short:

• Paint = often glows for days
• Smooth plastics or metal = may fade quickly
• Water = can stop the glow
• Encapsulation = glow may persist longer

In most cases, results are instant—you'll see a bright green glow appear under the UV light as you're spraying if lead is present.

However, some materials—like plastics, glazes, or coated surfaces—may encapsulate the lead beneath the surface. In these cases, the reagent may take longer to reach and react with the lead.

If you're unsure:

• Check the area again after a few minutes
• For stubborn or sealed materials, give it up to an hour and observe under the UV light again

If lead is present, you'll still see that distinct green glow eventually. When in doubt, repeat the test or apply a second drop of reagent to the same spot.

The shelf life of the Lumetallix reagent depends on how well it's stored.

• If you keep the cap tightly closed and store it at room temperature, the reagent can remain effective for 2 years or more.
• If the bottle is left open or not sealed properly, exposure to air can degrade the reagent, and its effectiveness may drop after around 6 months.

To get the longest life out of your kit:

• Always close the cap tightly after use
• Store the reagent in a cool, dry place away from direct sunlight
• Avoid contamination by not touching the dropper or spray tip to surfaces

If you're ever unsure about the age or performance of your reagent, do a quick test on a known lead-containing surface to verify that it's still working properly.

There are two simple ways to check:

1. Inspect the reagent:The reagent should be clear.If it has turned amber or yellow, it may no longer be effective and should be replaced.
2. Test the UV flashlight (LeadLight):Shine it on a white piece of paper. If the beam looks bright and even, it's working correctly.If it's dim or flickering, replace the battery.

Pro tip: If you plan to store your kit for an extended period, test it on a known lead surface before putting it away. This gives you a baseline to compare against when you use it again.
