About lumi clean

Lighting people

lumi clean is the cleanroom and hygienic-area lighting range from NMK Engineering Ltd, commercial lighting specialists based in Bangor, County Down. We’ve worked on commercial lighting projects for years, sourcing and specifying luminaires for projects of every size, and we supply customers across Europe.

The range covers sealed recessed panels for modular grid and plasterboard ceilings, in versions intended for different cleanroom classes; framed and frameless faces; standard and high colour rendering; glass and micro-prismatic diffusers; low-glare panels; corner and surface-mounted luminaires; and linear luminaires that fit between filter units in laminar-flow ceilings. We choose products for their sealing, materials, light quality and documentation, so you can specify with confidence and validate without surprises.

Who we work with

We work with architects, M&E consultants, cleanroom contractors, validation engineers and directly with facility owners: pharmaceutical and biotech manufacturers, electronics producers, food and drinks processors, laboratories and hospitals.

If you’re at an early stage, with a room data sheet and a ceiling plan rather than a full specification, that’s fine. We’ll help you work out which luminaires suit each room and what your validation team will need to see.

How we work

We’d rather help you get the installation right than sell you more luminaires. That usually means:

• Matching each luminaire to the room’s class, ceiling and cleaning regime
• Fitting the lighting around the filters and airflow, not the other way round
• Using the light level and colour rendering the task needs, and no more
• Being clear about what the manufacturer states, what has been tested and what still needs checking

Why clean areas need care

A cleanroom luminaire is part of the room’s envelope. It has to seal to the ceiling, keep particles out of the room, stand up to repeated cleaning and disinfection, and give good light for inspection and close work, often for years without being opened. In regulated areas it also becomes part of a qualified installation.

That’s why we put as much weight on sealing, materials and documentation as on light output. Our guides on cleanroom classes, IP ratings and sealing, materials and cleaning, colour rendering and planning cleanroom lighting set out how we approach each of these.

Manufacturing

Every lumi clean product is made by an established manufacturer with its own testing and quality systems. We bring the range together under one point of contact, so you deal with people who know the products and your project.
