E27 ES 110V rough service GLS lamps are 60W incandescent lamps built for site and industrial environments where vibration and mechanical shock cause standard lamps to fail prematurely. The 4.0mm lead wire supports the filament against vibration from plant, machinery, and site operations. They fit E27 (ES) fittings on 110V site supply.
How a 4.0mm lead wire makes this lamp suitable where standard bulbs fail
A standard incandescent GLS lamp uses a thin filament support wire. Vibration from nearby machinery, plant operations, or site traffic transmits through the lamp and causes the filament to fracture. The lamp fails, often within hours in heavy vibration environments. A rough service lamp uses a 4.0mm lead wire, significantly thicker than a standard lamp. This absorbs mechanical shock rather than transmitting it to the filament. The result is reliable operation in conditions that would destroy a standard lamp quickly.
Key Features
-
4.0mm rough service lead wire: Thick filament support designed for vibration and mechanical shock. The defining feature of a rough service lamp and the reason it performs where standard lamps fail.
-
E27 (ES) Edison screw cap: Standard E27 fitting. Screws directly into E27 sockets on 110V site supply fittings.
-
110V site voltage: Rated for UK construction site standard 110V CTE supply.
-
Clear GLS glass: Standard clear glass GLS shape. Delivers omnidirectional light output from the incandescent filament.
-
Specialist site application: Rough service lamps are exempt from UK incandescent lamp regulations when used in site and industrial vibration environments for which they are specifically designed.

Who is this for
This lamp suits site managers and site electricians who need reliable replacement lamps for E27 fittings on 110V site supply in areas subject to vibration. It is particularly suited to plant rooms where machinery creates constant ambient vibration, site compounds where vehicle movement transmits shock through structures, and any enclosed site area where standard lamps fail prematurely and require frequent replacement.
Typical applications
-
Replacement lamp for E27 fittings in plant rooms and machinery areas where vibration causes standard lamps to fail.
-
Site office, welfare cabin, and compound lighting on 110V supply where E27 fittings are installed.
-
Industrial and manufacturing environments where machinery vibration prevents standard GLS lamps from giving adequate service life.
-
Temporary site buildings and portacabins with E27 fittings on 110V site transformer supply.
How to use
Step 1: Switch off the fitting and allow it to cool before replacing the lamp.
Step 2: Remove the old lamp by twisting anti-clockwise until it releases from the E27 socket.
Step 3: Insert the new lamp by screwing clockwise into the E27 socket until it is firmly seated.
Step 4: Switch on and confirm the lamp is illuminated.
Safety
110V only. Do not use in 230V fittings. For site and industrial rough service use only. Not suitable for general domestic lighting applications under UK lamp regulations. Switch off and allow to cool before handling. Dispose of in accordance with UK WEEE regulations at end of service life.
Frequently Asked Questions
Q: What is a rough service lamp?
A: A rough service lamp is an incandescent lamp specifically designed for environments where vibration and mechanical shock would cause a standard lamp to fail prematurely. The key difference is the lead wire, the wire that supports the filament inside the bulb. This lamp uses a 4.0mm lead wire, which is significantly thicker than a standard lamp, allowing it to absorb vibration rather than transmitting it to the filament.
Q: Why does the 4.0mm lead wire matter?
A: In a standard incandescent lamp, the filament is supported by a thin wire. Vibration from machinery, plant, or site traffic causes the filament to oscillate and eventually fracture. A 4.0mm lead wire is thick enough to dampen this vibration before it reaches the filament. The result is a lamp that continues to operate reliably in conditions that would destroy a standard lamp within hours.
Q: Is this lamp legal to buy and use in the UK?
A: Yes. UK regulations banning standard incandescent GLS lamps apply to general-purpose lighting. Rough service lamps for industrial and site applications where vibration resistance is required are specifically exempt. This lamp is designed for site and industrial rough service use and falls within the exemption.
Q: What cap type does it use?
A: E27, also known as ES (Edison Screw). This is the standard screw-in fitting. Twist clockwise to fit, anti-clockwise to remove. It is not compatible with B22 or BC bayonet fittings.
Q: Is it compatible with 230V supply?
A: No. This lamp is rated for 110V only. Do not use in 230V fittings. For a B22 LED bulb compatible with both 110V and 230V supply, see ELB185LED.
Q: Where should this lamp not be used?
A: Not for general domestic lighting under UK lamp regulations. Not compatible with 230V supply or B22 bayonet fittings. Not for use in explosive or flammable atmospheres.
