Description
The Gowllands Spare Bulb 838 – Halogen is a replacement halogen lamp designed for use with compatible Gowllands diagnostic instruments and medical lighting systems. Supplied by Medisave (vendor Medscope), this spare bulb restores optimal illumination performance when the original lamp has failed or dimmed. It is a compact medical-grade halogen bulb engineered to deliver bright, clear light output suitable for clinical examination and minor procedures, providing a reliable and cost-effective way to extend the service life of Gowllands lighting equipment.
Bnefits
- Genuine spare halogen bulb designed for compatible Gowllands diagnostic instruments and medical lighting.
- Restores original light intensity and quality when the existing bulb becomes dim or fails.
- Medical-grade halogen technology offers bright, consistent illumination for clinical examination and procedures.
- Simple, low-cost component to extend the useful life of existing Gowllands devices without needing full replacement.
- Compact form factor compatible with designated Gowllands lamp housings for straightforward installation by trained staff.
Indications
- Replacement light source for compatible Gowllands diagnostic instruments (e.g., otoscopes, examination lights) originally supplied with a Gowllands 838 halogen bulb.
- Use in medical or clinical environments where a failed or degraded bulb needs to be replaced to maintain safe, effective illumination.
- Suitable for healthcare facilities, clinics and practices using Gowllands equipment that specifies bulb type 838.
Composition
- Glass envelope: heat-resistant, transparent glass lamp capsule enclosing the filament and halogen gas.
- Filament: tungsten filament engineered for halogen lamp operation.
- Fill gas: halogen gas mixture (e.g., iodine or bromine compounds in inert carrier) to support the halogen cycle and prolong filament life.
- Base/contact: metal base or pins designed to fit the compatible Gowllands lamp holder and provide electrical connection.
- Lead wires and internal supports: metallic components connecting the filament to the external contacts.
Packaging
- Supplied as a single spare halogen bulb (Gowllands type 838) per sales unit.
- Bulb is typically packed in a protective inner container (e.g., small carton or blister) to prevent damage during transport.
- Outer packaging / shipping materials provided by Medisave to protect the bulb in transit.
- Product listing on Medisave indicates it as a spare component within the Lighting/Accessories category.
Usage
- Switch off the instrument or lighting unit and disconnect it from the power source (or remove batteries) before attempting to change the bulb.
- Allow the existing bulb and lamp housing to cool fully if the light has been in recent use, as halogen bulbs can become very hot.
- Remove the old bulb according to the instrument manufacturer’s instructions (e.g., by gently pulling or twisting from the lamp holder).
- Avoid touching the new halogen bulb’s glass envelope directly with bare fingers; if necessary, handle with gloves or a clean tissue to prevent skin oils from shortening bulb life.
- Insert the Gowllands Spare Bulb 838 into the designated lamp holder, ensuring it is seated securely and that electrical contacts are properly aligned.
- Reassemble any covers or housings and reconnect the instrument or light to its power source.
- Test the light to confirm correct operation and adequate illumination before returning the device to clinical use.
- If the bulb fails to light or flickers, re-check installation and, if needed, consult the instrument’s user manual or a qualified technician.
- Only use this bulb in equipment that specifies compatibility with the Gowllands 838 halogen bulb type.
Contraindications
- Use in non-compatible instruments or lamp holders not designed for Gowllands 838 bulbs.
- Use in environments where halogen heat output could pose a risk if the instrument is not designed for this bulb type.
- Installation or replacement by untrained personnel where there is a risk of damage to the instrument or user injury.
Adverse Effects
- Risk of burns if the bulb or surrounding metal parts are touched soon after operation due to high surface temperature.
- Risk of cuts or minor injury if the glass envelope is broken or shattered during handling or installation.
- Risk of electric shock if the device is serviced or bulb replaced while connected to a live power source or if the instrument is damaged.
- Potential for inadequate illumination, misdiagnosis or eye strain if the wrong bulb type is installed or if the bulb is not functioning correctly.
- In rare cases, bulb rupture may occur at end of life or under fault conditions, potentially releasing hot fragments inside the lamp housing (normally contained by the instrument design).
Storage Conditions
- Store the spare bulb in its original protective packaging until use to minimise risk of breakage.
- Keep in a cool, dry place away from direct sunlight, excessive heat and moisture.
- Avoid strong vibrations, impact or dropping, which can damage the filament or glass envelope.
- Keep out of reach of children and unauthorised personnel.
- Store away from corrosive chemicals or environments that could degrade metal contacts or glass.
Duration
Not applicable \u2013 this is a medical device component (bulb). Functional lifetime depends on usage hours, operating conditions and instrument duty cycle; it should be replaced when it fails or when light output becomes inadequate for safe clinical use.
Onset
Immediate \u2013 full light output is achieved as soon as the instrument is correctly assembled, powered and the bulb is switched on.
