Buying colour matching cabinets in Bangladesh

A colour matching cabinet, or light booth, is a closed viewing box with a neutral grey interior and several switchable standard lights. Two samples that match under one light can part under another, and the cabinet shows it first. Its buyers are the labs of garment units and of dyeing, printing and finishing units, 342 of them in USDA's April 2026 count from BTMA data.

Cabinets go wrong quietly: a lamp ages, a counterfeit tube goes in, or the store light differs from the buyer's. A colour matching cabinet supplier in Bangladesh should guard against all three. Roptan sources from verified sellers, checks each source against your buyers' manuals, confirms genuine lamps and local service, and delivers. You deal with Roptan only.

Kinds of colour matching cabinet

Two-foot cabinets

About 600 mm wide. Compact units start at three sources, and two-foot models with five or six are sold in Dhaka. Choose one for lab dips, swatches and small panels.

Four-foot cabinets

About 1200 mm wide, usually with five or six sources. Choose one when whole garments or several bulk lots are viewed side by side against the standard.

Fluorescent cabinets

Fluorescent tubes for D65 daylight and a store light, such as the 4000 K narrow-band lamp or cool white, with tungsten A and UV. Choose it when your buyer's store light is fluorescent; logged hours decide when each tube is changed.

LED cabinets

One maker offers LED store sources at 3000, 3100, 3500 or 4000 K, or tuneable sets, built for booths. Choose LED when your buyer's retail lighting specification is LED.

How to brief a colour matching cabinet supplier in Bangladesh

Each source by type and temperature: Datasheets usually name lamps, not CIE numbers, so state type and colour temperature: the 4000 K narrow-band store fluorescent is CIE FL11, and cool white fluorescent is about 4230 K, FL2.
LED or fluorescent: Follow your buyer's store lighting. For LED, ask for a source built for booths: one maker warns that office LED retrofit tubes miss CIE illuminant tolerances.
Lamp hours: An hour meter on each source. One maker says fluorescent lamps that reach 2,000 hours within 12 months must be replaced; another counts each switch-on as roughly an hour.
Viewing angle and surface: Assessments are made at a set angle, so a 45 degree viewing table is sold as a booth accessory. AATCC sells a neutral grey card for mounting specimens.
Supply: Mains here is 50 Hz, and USDA reported frequent electricity shortages in April 2026. Ask whether the cabinet tolerates a low or interrupted supply.

Viewing standards for a textile colour cabinet

ASTM D1729-22: The current ASTM practice for judging colours and colour differences by eye under diffuse light; it recommends D65. ASTM shows the 2016 edition as historical.
AATCC EP9-2025: The textile procedure for judging colour difference against a standard by eye. Read it beside your buyer's own viewing specification.
ISO/CIE 23603:2024: Grades how well a lamp simulates daylight. It replaced ISO 23603:2005, now withdrawn. Ask the seller for the grade of the D65 source.
ASTM D4086-18(2023): The practice for visual evaluation of metamerism, for buyers who want proof that a shade holds across sources.

What moves the price of a colour matching cabinet

Sources: each extra light, a UV tube or an LED store-light set adds to the cost.
Size: a two-foot or a four-foot booth, and the viewing area it gives.
Controls: an hour meter per lamp, timers and automatic switching between sources.
Origin: in one Dhaka marketplace, two-foot cabinets of the same class from makers of different origins differ in price several times over.
Service: lamp measurement with a certificate, or a service contract, written into the quote.

Lead times and delivery

Time depends on the model and its route. A cabinet a seller already holds in Dhaka moves faster than one imported to order. An LED store source matched to your buyer's lighting, an extra source, spare lamps of the exact type or a lamp certificate can add time. Roptan confirms the delivery date in the quote.

Inside Bangladesh, Roptan delivers the cabinet to your lab with its power cable, fixings, assembly diagram, instruction book and switch panel guide, and the seller sets it up. A one-year parts warranty is usual; ask whether it covers lamp ageing, since one maker's does not. You receive the warranty card, any lamp certificate and a VAT invoice (Mushak 6.3).

What we check for this order

Sources match the manualWe check each lamp's type and colour temperature against your buyers' viewing manuals before the order, not after a failed approval.
Genuine lampsWe confirm where the seller buys lamps: one maker warns of counterfeit lamps sold through unauthorised distributors and gives no warranty on them.
Standards on the datasheetWe read the compliance claims. ISO 3668 and ISO 13076 are paint and coating standards, so we ask which textile practice applies.
Warranty and serviceWe confirm what the warranty covers, who services the cabinet in Bangladesh and whether its lamps can be measured and certified.

Questions buyers ask

Is an LED cabinet as good as a fluorescent one?

It can be, if its sources are made for colour viewing. One maker warns that ordinary LED retrofit tubes are not made to a tight tolerance to CIE illuminants. Choose the type your buyer's retail lighting specification names, and get each LED source's colour temperature in writing.

How often should cabinet lamps be changed?

Go by the hours on each meter. One maker says fluorescent lamps that reach 2,000 hours within 12 months must be replaced; another counts every switch-on as roughly an hour, so avoid short on and off cycles. Clean the grey interior, and have it repainted when it is dirty.

The datasheet says the cabinet meets ISO 3664. Is that enough?

No. ISO 3664 is a graphic technology and photography standard, and its 2025 edition says it does not apply outside those fields; the 2009 edition is withdrawn. For textiles, ask for ASTM D1729-22 and AATCC EP9 conditions, the ISO/CIE 23603:2024 grade of the daylight source, and your buyer's viewing specification.

Who should judge shades in the cabinet?

People with tested colour vision. The ASTM practice assumes observers with at least normal colour vision, preferably rated with a 100 hue test; one booth maker reports hereditary colour deficiency in some 8 percent of men and 0.4 percent of women. A 100 hue test kit is sold in Dhaka.
