UV-C Lamp Change Reminder Calendar — Month, Year & Lamp Length Dials

Description

When was that lamp last changed?

It’s the question nobody can answer. A UV-C lamp looks the same at 14 months as it does at 4 — still glowing, still drawing power, but well down on output. The paperwork says it was done. The paperwork is in a folder in an office three suburbs away.

This calendar puts the answer on the equipment itself. Three dials: the month and year the lamp was replaced, and the lamp length that went in. Set it when you fit the lamp and the next technician — or the next contractor, or the auditor — can read it in two seconds without opening a laptop.

The marker-pen problem

Everyone already has a system for this. It’s a sticker and a permanent marker — and in a plant room it its easy to forget, and then it stops working.

The marker fades. Condensation lifts the corner. Dust and grease settle into the ink until you’re squinting at something that might say 03/24 or might say 05/24. Someone crosses out the old date and writes the new one beside it, then the next person does the same, and within a few cycles there are four dates on a curling label and no way to tell which one is current.

Then there’s the practical problem: you have to be carrying a pen. Up a ladder, in a ceiling space, halfway through a service call with your hands full — the lamp gets changed and the label gets updated later, or tomorrow, or not at all. Nobody means to skip it. It just doesn’t happen.

There’s a professional angle too. A plant room where every UV unit carries a clean, matching, legible service plate reads very differently to a client or an auditor than one covered in faded stickers and biro. It signals the equipment is being looked after — which, if you’re the contractor maintaining it, is worth something on its own.

How it works

Three independently rotating wheels sit behind a black faceplate, each showing through its own window:

Each wheel is spring-tensioned. It turns with deliberate thumb pressure and then stays exactly where you left it — no drift from vibration, no slipping when the AHU runs, no need to tighten anything down.

Why bother

• Lamp output falls before the lamp fails. A germicidal lamp at 14 months is still lit but delivering materially less UV-C than it did on day one. Without a date on the unit there’s nothing prompting the change.
• Service records get separated from equipment. Contractors change, folders get lost, spreadsheets go stale. The plate doesn’t.
• It shows the right lamp. The length dial means whoever turns up next knows what to bring, rather than guessing or measuring.
• It’s visible during any inspection. If your maintenance regime gets audited, the evidence is on the equipment.

Specifications

Bespoke lamp-length wheels

The standard wheel carries the nine most common lengths in inches. If you service a fleet running one manufacturer’s equipment, we can produce the lamp-length wheel to that manufacturer’s own range instead — Steril-Aire, American Ultraviolet, sterilAir AG, Fresh-Aire UV, Australian Ultraviolet or others.

Useful if the lengths you actually fit aren’t on the standard wheel, or if you’d rather the plate showed part numbers your technicians already recognise. Tell us the manufacturer and the range you need and we’ll quote it.

Shipping

Flat $15 shipping Australia-wide, however many you order. One or fifty, the freight is the same.

Please note. This is a record-keeping and reminder device. It does not measure UV-C output, monitor lamp performance, or indicate whether a lamp is still delivering its rated irradiance — it records the date you set. Lamp replacement intervals should follow the equipment manufacturer’s guidance and your own maintenance schedule. If you need to know what a lamp is actually delivering rather than how old it is, that calls for a UV-C radiometer — we stock them, so ask us.
