Maintain a mapped exterior lighting installation through fixtures, drivers, power, control and scheduled scenes. HJ agrees safe access and the specialist electrical scope, records colour or output differences and supported parts, then verifies the affected zones without assuming a spot replacement will match aged fittings.
Conceptual planning path — not an as-built drawing or project photograph.
Tell us the fault and your location. Diagnostic attendance, repairs, parts and any travel charges are confirmed with you before work.

It sits in Architectural Lighting Service under Architectural Lighting. The final deliverable is shaped by the intended outcome, the installed or proposed environment and the interfaces that must be owned, supplied, integrated and tested.

From the initial brief to the handover record: what to prepare, check and confirm with HJ.

Fixture/driver/controller register, zone and address schedule, colour/output symptom, environment/ingress, safe access plan, supported parts and authorised show files.
Map fixture personalities, DMX addresses, Art-Net or other supported transport, controller outputs and power to the approved zone schedule. The show-file owner and electrical, structural and safe-access parties retain their assigned responsibilities.
Verify agreed channels, dimming, colour, cues and schedules at the actual viewpoints. Rehearse approved stop/restart and loss-of-control behaviour in a safe window; preserve field protection and record any discontinued or mismatched equipment.
Retain fixture/driver IDs, address/channel and network map, versioned show files where owned, authorised change list and witnessed visual tests. Document safe access, specialist responsibilities, remaining limits and approved follow-up.
HJ coordinates assessment, engineering, installation, integration, testing and lifecycle support only for the scope recorded in the quotation. ISD handles catalogue, model, datasheet, supply and availability enquiries. Customer, consultant, builder and appointed-specialist responsibilities remain explicit.
Regulated or multi-discipline work proceeds only after site assessment and confirmation of the competent, qualified or appointed persons, approvals, safe isolation and responsibility required for that scope.
Installed platform, authorised ownership, parts compatibility and serviceability are checked before any repair or restoration outcome is proposed.

Use the answers as a planning boundary; site conditions and written scope remain decisive.
Not necessarily. Confirm the exact fixture/driver, colour and control support, and review the affected zone on site. Age, optics and discontinued parts can limit matching; approve any wider replacement rather than promising identical output.
