Product Description
Just D65 4 Feet 58 Watt Artificial Daylight Tube
The Just D65 4 Feet 58 Watt Artificial Daylight Tube is an industry-benchmark color assessment lamp designed to reproduce standard CIE Illuminant D65 daylight conditions. Operating at a correlated color temperature (CCT) of 6500K, this specialized T8 fluorescent tube delivers balanced spectral energy across the visible spectrum (380 nm to 780 nm) along with controlled UV components. It serves as the primary visual inspection light source across Bangladesh’s textile, apparel, plastics, graphic arts, and packaging sectors.
In ready-made garments (RMG), fabric dyeing, and export quality control, shade variation and metamerism—where colors appear identical under factory lighting but mismatch under natural sunlight—lead to costly batch rejections. The Just D65 58W tube resolves this challenge by providing consistent, glare-free artificial daylight that adheres strictly to ISO 3668, ASTM D1729, and DIN 6173-2 standards. Its superior color rendering properties (Ra > 98) enable colorists, quality assurance managers, and lab technicians to detect the subtlest shade shifts, tint variances, and dye cast differences with total confidence.
Engineered with premium phosphors and robust dual-pin G13 end caps, this 58W (1500 mm / 4-5 ft nominal) fluorescent tube offers stable luminous output and prolonged operational life. It integrates seamlessly into standard multi-light color matching cabinets (such as CAC60/CAC120 or VeriVide booths) as well as overhead inspection luminaires in cutting and sewing lines. Victor Scientific Co. supplies 100% genuine, certified Just D65 daylight tubes with prompt delivery and technical support throughout Bangladesh.
✹ Key Features
Standard CIE Illuminant D65 Simulation
Accurately replicates 6500K natural northern sky daylight for internationally approved color assessment and shade matching.
Ultra-High Color Rendering Index (CRI Ra ≥ 98)
Provides museum- and lab-grade color fidelity, exposing metameric effects and minute color mismatches that standard commercial tubes conceal.
Controlled UV Component Integration
Includes a standardized ultraviolet fraction essential for activating optical brightening agents (OBAs) and fluorescent whitening dyes in textiles and paper.
Extended Service Life & Spectral Stability
Engineered with multi-band phosphors to deliver stable color temperature and consistent lumen output for over 2,000 burning hours.
Standard G13 Medium Bi-Pin Fitting
Universal 58W T8 standard bi-pin configuration fits directly into standard light booths, luminaires, and industrial proofing stations.
Compliance with Global Standards
Conforms to ISO 3668, ASTM D1729, DIN 6173-2, and major international garment brand visual audit protocols.

Frequently Asked Questions (FAQ)
A1
The price of the Just D65 4 Feet 58 Watt tube in Bangladesh typically ranges between BDT 3,500 and BDT 5,500 per piece, depending on import lot size, currency exchange rates, and bulk carton quantities. Contact Victor Scientific Co. directly for real-time rates and factory supply discounts.
Q2
What is the difference between D65 and a standard 6500K household daylight tube?
A2
Standard commercial 6500K tubes have a low Color Rendering Index (CRI 70-80) and irregular spectral spikes that distort colors. The Just D65 tube provides a continuous spectrum with CRI Ra ≥ 98 and a controlled UV proportion to accurately evaluate optical brighteners (OBAs) and true color shades.
Q3
When should a D65 tube be replaced in an RMG or textile testing lab?
A3
For audit compliance (such as ISO and buyer accreditation), D65 tubes should be replaced every 2,000 burning hours or every 12 months, even if they still emit light, as spectral output and color temperature degrade over time.
Q4
Can this 58W tube be used in standard light matching cabinets?
A4
Yes, this 58W tube (nominal 4–5 ft / 1500 mm length) is designed to fit large viewing booths, inspection tables, and overhead luminaires configured for standard G13 T8 sockets.
Q5
Does Victor Scientific Co. supply these fragile tubes safely outside Dhaka?
A5
Yes, Victor Scientific Co. packs all glass fluorescent tubes in shockproof, reinforced cylindrical casing and delivers across all industrial zones including Gazipur, Narayanganj, Savar, Chattogram, and Cumilla via reliable courier services.
