Light-as-a-Service

Buy lighting performance over time instead of buying luminaires outright, so the provider has a commercial reason to design, maintain, upgrade, and recover the physical system.

Also known as: lighting-as-a-service; circular lighting; pay-per-lux; managed lighting service

Understand This First

• R-Strategies (R0–R9 / 9R Framework) — the value-retention hierarchy behind repair, reuse, and recycling.
• Buildings as Material Banks (BAMB) — the asset frame that makes installed components worth tracking.
• Material Passport — the evidence layer needed to manage products through service, maintenance, and recovery.

Context

Lighting is one of the cleaner places to see product-as-a-service in buildings because the user does not really want fixtures. The user wants safe, reliable, comfortable light at the right intensity, in the right spaces, for the right hours, with as little disruption as possible. The luminaire, driver, sensor, cable route, control system, maintenance visit, and end-of-life take-back are means to that end.

Light-as-a-Service turns that fact into a contract. Instead of selling the client a set of luminaires and walking away after installation, the provider sells lighting performance over a defined term. In the best-known circular versions, the provider or service consortium keeps ownership of the fixtures, designs them for maintenance and disassembly, measures performance, replaces components when needed, and takes responsibility for reuse or recycling at the end of the contract.

The pattern sits in the business-models section because the circular move is not the LED itself. Efficient LEDs reduce electricity demand, but they don’t automatically preserve material value. The circular move is the alignment of ownership, maintenance, data, and recovery incentives so the party that controls the product also benefits from longer life, repairability, and recoverable components.

Problem

A conventional lighting procurement pushes the manufacturer toward a sale and the owner toward a capital purchase. Once the fixtures are installed, maintenance becomes the owner’s problem. If a driver fails, tenant requirements change, or a control system ages badly, the easiest response may be replacement. At strip-out, luminaires can become anonymous waste electrical equipment even when many components still have usable value.

The incentives are split. The manufacturer may know how to design a repairable, modular, longer-life fixture, but the upfront tender may reward lower purchase price. The owner may want lower whole-life cost, but the budget line may separate capital expenditure from maintenance, energy, replacement parts, and end-of-life recovery. Circularity loses in the accounting before it reaches the ceiling grid.

Forces

• The client buys an outcome, not a product. Light levels, reliability, user comfort, energy use, and uptime matter more than fixture ownership.
• The provider controls design choices. Modular parts, accessible drivers, standard components, and take-back routes are easiest to specify before manufacturing and installation.
• Capital budgets can block good retrofits. A service contract can move cost from upfront purchase to operating expenditure, but that shift has accounting and credit consequences.
• Long-term duties need real pricing. Maintenance, replacement, performance monitoring, insurance, finance cost, and recovery can’t be treated as free extras.
• Lighting changes with use. Tenant churn, control upgrades, code changes, and space reconfiguration can make a static product purchase age badly.

Solution

Contract for delivered lighting performance and attach ownership, maintenance, data, and recovery duties to the party best placed to manage the system. The contract should define the performance service in operational terms: lux levels, uptime, energy performance, response times, comfort constraints, control functionality, replacement rules, reporting duties, and end-of-term options.

The provider’s ownership matters only if it changes behavior. A serious Light-as-a-Service contract should make repairability, modular replacement, product identification, maintenance records, and recovery routes part of the commercial model. If the provider owns the luminaires, every early failure, awkward replacement, bespoke part, and unrecoverable assembly becomes their cost over the contract term. That is the incentive shift.

The contract also needs a finance and accounting spine. The client may prefer a periodic service charge to a capital purchase, but the arrangement can still create balance-sheet, lease-accounting, procurement, tax, and lender questions. Those questions are not side issues. They determine whether the contract is a bankable performance service or a clever procurement story that collapses during approval.

Finally, define the end of the service term before signing. The client may extend the contract, upgrade the existing installation, buy out assets, transfer fixtures, return luminaires for reuse, or send components through a documented recycling route. Without those options and evidence duties, “as-a-service” can become a payment mechanism rather than a circular product system.

How It Plays Out

The canonical case is the Schiphol Airport Lounge 2 lighting contract announced by Philips, Schiphol, and Cofely in 2015, with Turntoo and Thomas Rau associated with the circular business-model thinking behind it. Schiphol paid for lighting performance while Philips retained ownership of the fixtures and Philips and Cofely carried performance, durability, maintenance, and end-of-life duties. The reported design move was not only an LED retrofit. The fixtures were designed so components could be replaced separately, extending service life and reducing the need to discard whole fittings.

In an office retrofit, the same pattern starts with a facilities brief rather than a product schedule. The owner specifies light levels, occupancy profiles, meeting-room needs, maintenance windows, control integration, and reporting duties. The provider chooses the equipment, installs sensors and controls, maintains the system, tracks product identity, and replaces drivers, modules, or lenses without turning every failure into a new procurement event. The owner buys reliable light; the provider manages the physical stock.

A warehouse case looks different. Here the client may care most about energy use, uptime, safety, and avoiding disruption across high-bay areas. A service provider can fund the retrofit, maintain fixtures, tune controls, and earn margin through reduced energy and maintenance cost over time. The circular result depends on whether the luminaires are designed and recorded for later reuse, not only on whether the energy bill falls.

A weak version is easy to sell and hard to defend. The provider installs ordinary fixtures under a monthly payment plan, promises “circular lighting,” and keeps vague end-of-life language in the appendix. There is no component-level record, no modular repair strategy, no take-back route, no condition grading, and no buyer for reused equipment. The client may still get better lighting and lower energy use, but the circular claim is thin.

Consequences

Benefits

• Aligns the provider’s profit with longer product life, repairability, efficient operation, and recoverable components.
• Can reduce the owner’s upfront capital barrier for lighting upgrades when the accounting treatment is acceptable.
• Gives the facilities team a single service duty covering performance, maintenance, replacement, and reporting.
• Creates a live data trail for energy use, operating hours, maintenance history, product identity, and end-of-term decisions.
• Makes product design choices visible: modularity, standard parts, replaceable drivers, accessible controls, and fixture disassembly become contract-relevant.

Liabilities

• Shifts risk rather than removing it. The provider must price finance cost, performance guarantees, asset ownership, maintenance labor, insurance, recovery, and technology change.
• Can become a Performance-Contract Risk Dump if the provider accepts long-tail duties without enough margin, control, or finance capacity.
• May create accounting, procurement, lease, tax, and lender issues that a simple purchase would not trigger.
• Doesn’t automatically produce reuse. Fixtures still need product records, modular construction, condition evidence, return logistics, and a secondary-use or recycling route.
• Can reduce owner flexibility if the contract term, controls platform, replacement rights, or buyout options are poorly drafted.
