Philips TL-D 18W/33-640 Cool White CWF Fluorescent Tube – 2 Feet
The Philips MASTER TL-D 18W/33-640 Cool White fluorescent tube is a professional linear fluorescent lamp suitable for use in compatible colour matching cabinets, colour inspection booths, visual quality-control stations and industrial lighting fixtures.
This 2-feet tube produces a Cool White light with a nominal correlated colour temperature of 4100K. It is commonly used as one of the illuminants in multi-light colour matching environments, allowing users to inspect the appearance of colours under different lighting conditions.
The lamp uses a T8 tubular design with G13 medium bi-pin caps and is designed for compatible fluorescent lighting systems. With an 18W power rating and nominal luminous flux of approximately 1,200 lumens, it provides a practical replacement solution for existing colour inspection cabinets and compatible industrial fixtures.
Suitable Applications
- Colour matching cabinets and light booths
- Paint and coating inspection areas
- Automotive refinishing and colour evaluation
- Printing and packaging colour inspection
- Textile and plastic colour comparison
- Industrial quality-control workstations
- Compatible fluorescent fixtures requiring an 18W T8 Cool White tube
- Replacement lamp for multi-illuminant visual inspection systems
Why Use Multiple Light Sources for Colour Evaluation?
A colour can appear different under different light sources. Professional colour matching cabinets therefore use multiple illuminants to help identify possible colour differences and metamerism.
The Philips TL-D 18W/33-640 Cool White lamp can be used as one of the compatible illuminants in such multi-light inspection systems, alongside other specified light sources such as D65, UV and other lamps depending on the design and requirements of the colour matching cabinet.
Note: This lamp has a nominal CRI of 63 and it’s not a high-CRI precision daylight lamp. For critical colour evaluation, use the complete illuminant system and operating conditions specified by the relevant colour-matching procedure or equipment manufacturer.
