UV Lamps & Consumables

UV lamps, quartz sleeves and ballasts are the consumable parts of a UV sterilizer and must be replaced on schedule; SIVAT matches replacements from a model number or a nameplate photograph.

If you know the model, send it and we will match it. If you do not, send a photograph of the nameplate and we will identify it.

Why lamps get replaced on schedule, not on failure

A UV lamp does not stop working when its output falls below specification. It keeps lighting. Output declines steadily across lamp life, and a lamp at the end of its rated hours can be delivering a fraction of its original intensity while looking completely normal through the sight port.

This is the most common reason a UV system quietly stops doing its job. Everything appears to be running. The dose being delivered is no longer the dose the system was designed around.

Lamps are specified with a rated life in operating hours. Replacement is scheduled against that figure, not against failure.

What else is consumable

Quartz sleeves. Scale and biofilm on the sleeve reduce UV transmission independently of lamp condition. Sleeves should be cleaned on a routine schedule and replaced when clouding, damage, or degradation makes cleaning ineffective. Systems with automatic wipers still require periodic sleeve inspection and service.

Ballasts. Electronic ballasts have a finite life and typically outlast several lamp sets, but they do fail, and a failed ballast on a critical animal system is an emergency.

Wiper seals and drive components on units fitted with automatic cleaning.

O-rings and gaskets, which should be replaced whenever a chamber is opened rather than reused.

Why correct matching matters

Lamps are not interchangeable across manufacturers, even where physical dimensions appear identical. Output, arc length, base configuration, and ballast compatibility all have to match. A lamp that physically fits and is electrically wrong will either fail early or deliver the wrong output.

Low-pressure amalgam and medium-pressure lamps are entirely different components with different life expectancies, different output profiles, and different ballast requirements.

Sleeve dimensions are specific to the chamber. A sleeve that is close but not correct can leak, fracture, or fail to seal properly.

Keeping spares on site

For a critical animal system, keeping a spare lamp set on site can reduce operational risk. Specialty aquatic UV lamps may have meaningful lead times, and facilities should plan replacement inventory around the consequences of an outage.

We recommend a full spare lamp set and at least one spare sleeve for any critical system, ordered with the original equipment rather than after the first failure.

How SIVAT helps

Send a model number, a nameplate photograph, or the original submittal, and we will identify the correct lamp, sleeve, and ballast and quote them. We also supply lamps for systems SIVAT did not originally provide.

For facilities running several UV units, we can build a consolidated consumables list with replacement intervals so ordering happens on a schedule instead of after a problem.

Notes

Photography direction differs for these two.

Degas Towers follows the standard rule, lead with the installed tower in a facility, support with the product shot. Your deck already contains a tower image.

Lamps is the exception. Lead with the product. The visitor is matching a part, and a clean photograph of a lamp and sleeve is more useful to them than an equipment room. This is the one equipment page where the catalog image is correct.

Lamps also behaves differently from every other page in the set. It targets an operator with a failed component, not a contractor pricing a bid, different search intent, different urgency, no interest in a relationship. Structure it for someone in a hurry: model matching first, technical explanation second.

Worth watching in analytics. If it converts, it justifies a broader consumables and spares section, which is recurring revenue and a route into facilities that already own systems.
