Stage lighting is awkward inventory. Half the stock hangs in the air on bars and truss, the rest lives in flightcases that all look the same, and everything gets rigged, derigged and trucked by tired crews working against a deadline. Theatres, venues, churches and hire companies all hit the same wall: the rig on paper drifts away from the rig that exists. This guide builds a fixture-level register that survives load-ins, hires and relamps.

How fixtures disappear
Lighting stock rarely walks out of the stage door under someone’s arm. It evaporates in quieter ways:
- It stays rigged. A pair of profiles left on a bar after a one-off become part of the venue’s furniture. Six months later nobody remembers they were yours.
- Spares migrate. The moving head swapped out mid-run goes back into whichever case has room, and the case manifests stop meaning anything.
- Accessories belong to nobody. Clamps, safety bonds, omega brackets, gel frames and barn doors are cheap individually and crippling collectively - a fixture without its clamp and bond cannot go up.
- Hires come back short. Without a counted check-in, a missing fixture surfaces at the next prep, weeks after anyone can say which job failed to return it.
The result is a register full of ghost assets - fixtures that exist on paper but not on the shelf - and a prep day that starts with a search instead of a pick list.
What to record for every fixture
Track at fixture level, not line-item level. “8x LED par” tells you what you bought; it cannot tell you which unit came back from the arts centre with a cracked lens.
| Field | Why it matters for lighting |
|---|---|
| Asset ID | The number on the label - what crew quote when a fixture fails mid-focus |
| Type + model | ”Moving head” describes half the store; the model determines weight, mode and hire price |
| Serial number | Insurance claims and theft reports - the one ID a thief cannot peel off |
| Status | In use, in storage, in repair, retired - so pick lists draw from reality |
| Location | Venue, bar position or case number - “LX2 at the arts centre” beats “out” |
| Accessories | Clamp, safety bond, omegas, gel frame - defines what “complete” means at check-in |
| Electrical-test date | Venues and clients ask for in-date test records before you plug in |
| Source hours | Discharge lamps have finite life; logged hours tell you when to budget relamps |
| Condition + photos | Cracked lenses, dead pixels, failing pan belts - with evidence and dates |
Counting accessories sounds excessive until the third load-in in a row stalls because forty clamps have quietly become twenty-eight.
Labelling kit that gets hot, rigged and trucked
Lighting punishes labels: fixtures run hot, get gripped by gloved hands, dropped into cases and slid across truck floors. Placement matters more here than on almost any other equipment.
- Label the base or yoke, never the head. On a moving fixture the head runs hottest and moves constantly; the base is cooler, static, and faces you in the case.
- Keep labels off vents, handles and gel runners. Anywhere hands or heat reach, the label dies.
- Use laminated polyester stock. Paper labels do not survive one festival season.
- Label the flightcase as well as the fixture, and record the case’s contents against it. An empty slot in a labelled case is how a missing fixture announces itself.
- Do not serialise cable and gel. Track tape, gel and spare lamps as counted consumables; individual QR labels on every TRS cable is a project that never gets finished.
Tip: apply labels at the service bench or during prep, never at height. A label applied from a focus ladder ends up crooked, half-stuck and unscannable from the ground.
Check-outs for shows, hires and loans
A lighting store has three flavours of “out”, and all three deserve the same treatment: a recorded check-out with a name and a date.
- Shows in your own spaces: check fixtures out to the production or the room. When the run ends, the check-in is your derig count.
- Hires: check kit out to the client with a due date, and record condition with photos at dispatch and at return. That record is the difference between charging for a smashed lens and arguing about one.
- Loans: the borrowed fresnel with no paperwork is the one that never comes home. A one-line check-out takes less time than the favour deserves.
Counting back in against the check-out list, case by case, catches shortages while they are still recoverable - the venue still remembers your profiles being on the boom. It also builds a clean chain of custody for the kit that crosses your dock most often. The same model extends to the rest of a production store - see the guide to event equipment tracking.
Maintenance, testing and lamp life
Lighting faults are constant, small and easy to lose: a flickering fixture is noted verbally at derig and forgotten by the next prep. Attach faults to fixtures, not to memory.
- Report faults against the asset ID the moment a unit misbehaves, with a photo. A fixture marked “in repair” cannot be picked for the next job by mistake.
- Track electrical-test dates and filter for anything going out of date before it goes out on hire.
- Log relamps and source hours so lamp budgets are planned rather than discovered.
- Inspect rigging accessories. Bonds and clamps are safety-critical; a date field and a habit cover most of it.
- Retire, never delete. A retired fixture’s repair history is the evidence for the next purchasing decision.
Tools that make this easier
A spreadsheet can hold every column in the table above, and most lighting stores start there. It fails at the dock: nobody updates a sheet during a 2 a.m. load-out, so the register decays one show at a time until prep becomes archaeology.
AMPthilly is built around the moments the sheet misses. Every fixture gets a profile with serial, accessories, documents and photos; printable QR labels open that profile when scanned with a normal phone camera in the browser, no app install; check-outs to a client, venue or production carry due dates and an overdue list; and faults reported from the floor stay on the fixture’s history permanently. The free plan covers 3 users and 25 assets - enough to register the moving heads and consoles first - and the pricing page covers the tiers above that.
FAQ
How do I keep track of stage lighting equipment? Fixture-level records, durable labels, and every movement - show, hire or loan - recorded as a check-out with a name and date. Count back in against that list at derig.
Where should QR labels go on lighting fixtures? Base or yoke: cool, static, and visible in the case. Laminated polyester stock, away from vents and handles, with a matching label on the flightcase.
How do lighting hire companies keep track of fixtures? Per-item check-outs against a client and a due date, condition photographed at both ends, and a count-in on return day so shortages surface immediately.
Should I track clamps, safety bonds and rigging accessories? List them on the fixture profile as part of “complete” and count them at check-in. Bulk stock like gel and lamps works better as counted consumables.
What should a stage lighting inventory include? Asset ID, type and model, serial, status, location or case, accessories, electrical-test date, source hours, and condition notes with photos - plus purchase details for insurance.
The takeaway
Lighting stock disappears at height, in the dark and on a deadline, so build the register around the dock rather than the desk: fixture-level records, labels on the cool static parts, every exit a check-out, every return a count. Do that and prep day starts from a pick list, not a search party.
