Bathroom Mirror Cabinet 900mm with Integrated LED Lighting – Factory Specifications

This document details the engineered specifications of a 900 mm wide mirror cabinet equipped with factory‑installed LED illumination, intended for installation in wet‑environment applications such as hotels, hospitals, and residential bathrooms.

Key Technical Parameters

The following table lists nominal values that are typical for this product; actual dimensions can be adjusted per project requirements.

These parameters collectively determine thermal management, electrical safety, and mechanical stability under continuous humid conditions.

Materials and Construction

The cabinet body is fabricated from 18 mm moisture‑resistant medium density fibreboard (MDF) with a density of approximately 700 kg/m³, providing dimensional stability after repeated humidity cycles. All exposed edges are sealed with 0.5 mm PVC edge banding to prevent water ingress.

The mirror panel uses 5 mm tempered low‑iron glass, selected for its high light transmittance (≥ 89 %) and reduced greenish tint. A safety film is laminated to the rear surface to hold fragments together in case of breakage, meeting typical safety glass standards.

LED illumination is provided by a flexible SMD 2835 strip mounted within an aluminum extrusion that acts as a heat sink. A polycarbonate diffuser with a matte finish ensures uniform luminance distribution and minimizes direct glare (UGR < 19).

Lighting Performance

The LED system delivers a nominal luminous flux of approximately 990 lm across the 900 mm width, resulting in an average illuminance of about 200 lux at the mirror surface when measured at a distance of 200 mm. This level is sufficient for grooming tasks while maintaining comfortable ambient lighting.

Color temperature stability is maintained within ± 150 K over the rated lifespan, and the CRI of ≥ 80 ensures accurate color rendering for skin tones and cosmetic products. The driver incorporates over‑current and over‑temperature protection to prolong LED life.

Installation and Mounting

Mounting is achieved via four concealed zinc‑alloy brackets screwed into wall studs or suitable anchors. Each bracket is rated for a 150 kg shear load, providing a total safety factor well above the expected load of the cabinet and mirror assembly (approximately 30 kg).

Electrical connection is made through a rear-accessible wiring compartment rated IP20. A clearance of at least 20 mm behind the cabinet is recommended to accommodate the driver and facilitate service. The unit is designed for direct wiring to a 12 V DC supply or to an included AC‑to‑DC adapter.

Applications in Commercial and Residential Settings

In hotel bathrooms, the cabinet’s moisture‑resistant construction and easy‑clean surfaces support high turnover cleaning regimens while maintaining appearance over years of use. The integrated LED eliminates the need for separate vanity lights, reducing installation complexity and maintenance points.

Healthcare facilities benefit from the low‑VOC materials and sealed edges, which minimize particle shedding and simplify infection‑control protocols. The IP44 front face protects against splashes, making the unit suitable for areas near sinks and showers.

For residential installations, the product offers a streamlined aesthetic with uniform illumination that enhances task lighting without creating harsh shadows. The tempered glass and safety film add an extra layer of protection in family bathrooms.

Quality Control and Testing

Prior to shipment, each unit undergoes a humidity cycling test: 48 hours at 90 % relative humidity and 38 °C, followed by a drying period, to verify that no delamination or warping occurs. Thermal shock testing cycles the assembly between –20 °C and +60 °C for 20 cycles to assess joint integrity.

LED performance is validated using an integrating sphere to measure luminous flux and CRI, with a target lumen maintenance (L70) exceeding 30 000 hours under driven conditions. Electrical safety is confirmed by a dielectric strength test of 1500 V AC between live parts and accessible conductive parts, with no breakdown observed.

Customization Options

• Overall width, height, and depth adjustable in 50 mm increments
• LED color temperature selectable from 3000 K to 6000 K in 500 K steps
• Presence‑activated motion sensor or touch‑switch activation
• Integrated demister pad (12 V, 40 W) for fog‑free mirror
• Alternative finishes: melamine laminate, wood veneer, or powder‑coated aluminum frame
• Input voltage options: 110 V AC or 220 V AC with appropriate driver

Frequently Asked Questions

Can the cabinet width be adjusted to fit a specific opening?

Yes, the cabinet width can be customized in 50 mm increments between 600 mm and 1200 mm. Provide the required opening dimensions when requesting a quotation.

What information is needed before a quotation can be issued?

To prepare a quote we require the desired overall dimensions, lighting specifications (color temperature, sensor options), finish selection, and any additional features such as a demister or integrated power outlet.

Which materials are available for the cabinet body?

Standard construction uses 18 mm moisture‑resistant MDF with PVC edge banding. Alternatives include marine‑grade plywood, aluminium extrusion frames, or high‑pressure laminate panels, all of which can be supplied upon request.

How is the LED lighting quality verified during production?

Each LED strip is tested for luminous flux, color temperature, and CRI using a calibrated spectroradiometer. Bins are selected to maintain a tolerance of ± 150 K and CRI ≥ 80 across production lots.

What packaging methods protect the mirror surface during shipping?

Mirrors are separated by interlocking corrugated inserts and wrapped in low‑static polyethylene foam. The assembled cabinet is placed in a double‑wall carton with corner protectors and sealed with polypropylene strapping to withstand typical handling and transit vibrations.
