Most UV indicators on the market only have one color scale.

Kolorguide UV Tests, on the other hand, include two distinct scales:

• H-BULB (Mercury)
• D-BULB (Iron-doped)

Why does this difference matter?

Because H-Bulb and D-Bulb emit different UV spectra. Even though both are UV-A lamps, their energy distribution is not the same. Using the wrong scale can lead to:

• Over-curing (wasting energy and time)
• Or under-curing (risking poor adhesion, low resistance, and customer complaints)

With the Kolorguide reference guide, you get the correct reference for each lamp type, allowing you to:

• Accurately monitor real intensity
• Maintain consistency in your process
• Avoid costly curing errors

Shorter version (ideal for Instagram / LinkedIn):

Kolorguide UV Tests are different.

While most brands only offer one scale, we provide two: one specific for H-Bulb and another for D-Bulb.

Why? Because different lamps = different UV spectra. Using the wrong reference can lead to inaccurate curing results.

Precision matters in UV curing.

Measure correctly. Cure confidently.

Visual tip: Use the photo you shared (the Kolorguide chart clearly showing both H-Bulb and D-Bulb columns). You can crop or highlight the two scales to make the difference even more obvious.
