GHO1148T5L UV lamp Oman — 120W 1148mm high output industrial germicidal bulb

GHO1148T5L UV lamp Oman

The GHO1148T5L UV lamp is a 120W high output germicidal tube, 1148mm long on a 4-pin base, and UV Water Systems supplies it in Oman for industrial UV reactors. This is the lamp size used where flow is measured in cubic metres per hour rather than gallons per minute — multi-lamp banks on process water, potable supply to large facilities, and treated effluent reuse.

On a multi-lamp reactor, lamps are replaced as a set rather than one at a time. Mixing a new 120W tube with tubes at 8,000 hours produces an uneven dose profile across the chamber and defeats the point of the redundancy the bank was designed for. Budget the full set at each change interval and keep one spare on the shelf for a mid-cycle failure.

Replacement for like-for-like 120W 1148mm 4-pin germicidal lamps

Confirm the ballast rating before ordering. 120W high output tubes need a matched HO ballast, and on multi-lamp reactors each lamp usually has its own driver. If one position keeps failing while the others run normally, the ballast on that position is the likely fault, not the lamp.

Where the GHO1148T5L UV lamp Oman is used

We supply this size to oil and gas facilities, industrial plants, large hospitals and district cooling installations across Oman. UV Water Systems designs, installs and maintains industrial UV disinfection for high-flow duties, and can provide UV intensity readings and lamp change records for the maintenance file.

When to replace your GHO1148T5L UV lamp Oman

UV-C output decays long before the lamp stops lighting. A germicidal lamp still glowing at 15 months may be delivering well under the dose its chamber was sized for, which means the water leaving the system is no longer being disinfected to specification. Replace on hours, not on appearance. For systems running continuously, that means once every 12 months. Log the change date on the controller or on the chamber label so the next service is scheduled rather than remembered.

Handle the quartz sleeve at the same visit. Scale and iron deposits on the sleeve block UV-C just as effectively as a weak lamp, and in Oman’s high-hardness groundwater sleeves foul faster than most manufacturers’ generic guidance assumes. Clean the sleeve with a mild acid descaler, inspect the O-rings, and replace the sleeve outright every three to five years.

Standards and references

The UV dose a chamber must deliver, and the reasoning behind the annual lamp change, come from published drinking water guidance rather than from equipment marketing. The WHO Guidelines for Drinking-water Quality set out the microbiological targets disinfection is designed to meet, and the International Ultraviolet Association publishes the dose and validation practice the industry works to. We size and service UV systems in Oman against those references.

Buying GHO1148T5L UV lamp Oman in Oman

UV Water Systems has supplied and serviced ultraviolet disinfection equipment across the Sultanate for more than 14 years, for hospitals, oil and gas sites, schools, hotels, food and beverage plants and villas. We stock germicidal lamps and ballasts in Muscat rather than ordering them in after a failure, so a plant that loses disinfection on a Sunday morning is not waiting three weeks for an air freight shipment.

Every lamp we supply is a named-manufacturer part with traceable 254 nm output data — the documentation health authority and HACCP auditors in Oman ask for. Our technicians cover Muscat, Sohar, Nizwa, Salalah and Duqm, and can carry out the lamp change, sleeve clean and UV intensity check as one visit under an annual maintenance contract.

Uniqueness View LLC is ISO 9001:2015 certified. Call +968 9763 7786 or email sales@waterfilteroman.com for stock availability, bulk pricing on service-contract quantities, or help identifying the correct lamp for a chamber you cannot find a part number on. Send us a photo of the old lamp and the chamber label and we will identify it for you.
