Every 2,000 - 3,000 hours or manufacturer recommendation to maintain consistent light and color quality.

Standard models are available in a range of sizes, starting from small desktop units which are roughly the size of 60 x 40 x 40 cm, and extending to larger units which are about 120 x 60 x 80 cm based on what you need them for.

The color measurement theory is the quantification of the interaction of materials with light, either absorption, transmission, or reflection. It employs standard colour spaces (such as CIELAB) and devices (colorimeters, spectrophotometers) to code the visual colour into objective and reproducible data.

The color of chemical products is measured by using a colorimeter or spectrophotometer. The instruments measure the amount of light that gets absorbed or reflected by a substance. It may be used to determine concentration, purity, or compliance with product standards.

Flickering lamps, color shifts, and uneven lighting are common faults, which can be corrected by changing the tubes, cleaning the interiors, and re calibrating the light system.

The accuracy of colors is determined by comparing the values of the colors (L*a*b*) of a sample with a standard reference sample using tools such as spectrophotometers. The variation is measured as ΔE. The smaller the value of ΔE, the more accurate, the nearer to the target color.

Yes, we offer free samples for test, you are welcome to order samples to experience our excellent quality and service.

To answer this question, you first need to clarify your specific needs: 

• Is it for simple color quality control (QC)?

• To coordinate with supply chain color management?

• To monitor on-line color stability?

• Do you require computer color matching or production color correction?

• What is your budget?

• Systematic supervision and evaluation of color performance in dyed products?

If you aren’t fully clear about your requirements at the initial stage, our color management engineers are ready to communicate with you. We will recommend solutions tailored to your needs. When conditions permit, we can provide prototype demonstrations and trial testing to ensure the instrument meets your practical application requirements.

For a proper color evaluation, ensure cleanliness, use standardized observation conditions, eliminate stray light, and periodically change the lamps.

Yes. However, for LED retrofitting to meet industry standards, color- calibrated LED modules must be used for accurate color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses
