Gooseneck Arm Quartz Halogen Lamp

Quick Answer: The Gooseneck Arm Quartz Halogen Lamp is a bright halogen light on a flexible gooseneck arm that stays in whatever position it is bent into, used to light opaque specimens from above. A gooseneck halogen lamp lets the user choose the angle of light for each specimen.

Directional Light for Relief and Texture

Opaque specimens reveal their shape through shadows. Light from directly above flattens them, while light from the side at a low angle makes ridges, pits and hairs stand out. The gooseneck arm makes that angle easy to set and change: bend it low for the surface of a fossil, then swing it higher to show the colours of a flower. The arm stays where it is left, so both hands remain free for forceps and needles.

Quartz halogen bulbs give a bright, warm-white light that renders colours well, which is why they have long been used for microscope illumination. They also run hot, both at the bulb and at the lamp head, so the head should not stay close to delicate or living specimens for long periods. The listing does not state the wattage, the number of arms or whether a dimmer is fitted, so confirm them at enquiry.

The Positionable Goose-Neck Illumination System is listed as a complete lighting system, whereas this lamp is named specifically for its quartz halogen source. For cool light on living specimens, the Optical Fiber Lamp keeps the heat back at its housing.

Care & Handling

• Never touch the quartz bulb of the gooseneck halogen lamp with bare fingers; skin oils create hot spots that shorten its life, so change it using a clean cloth or gloves.
• Let the lamp head cool before bending the arm near your hand or packing the lamp away.
• Bend the arm gradually along its length rather than kinking it at one point.
• Keep paper, plastic specimen bags and other flammable material away from the hot head.

Applications

• Oblique lighting of fossils, rocks and minerals to show surface relief
• Lighting dissections under a stereo microscope
• Inspecting engraved, cast or machined surfaces
• Photographing specimens where the direction of light must be controlled

Frequently Asked Questions

What does quartz halogen mean?

The bulb has a tungsten filament inside a small quartz envelope filled with halogen gas. The halogen cycle returns evaporated tungsten to the filament, and quartz withstands the high temperature, so the bulb gives bright, white light from a compact source.

Why did my halogen bulb fail early?

Fingerprints on the quartz, knocks while the filament is hot, and a supply voltage above the rating all shorten bulb life. Handle new bulbs with a cloth and avoid moving the lamp roughly while it is on.

How close can the lamp be to a living specimen?

Keep it far enough away that the back of your hand, held where the specimen sits, does not feel warm. Switch off between observations, or use a cool source such as a fibre optic or LED light for long sessions.

How do I light a specimen to show texture?

Bend the arm so the light strikes the surface at a low angle, roughly 10 to 30 degrees, from one side. Rotate the specimen until the shadows show the feature you want, then draw or photograph it.

Can the gooseneck lamp be used with a compound microscope?

It can act as an external source for a mirror microscope or light an opaque object from above, but compound microscopes normally light slides from below. The lamp is mainly suited to stereo microscopes and magnifiers.

What replacement bulb does it need?

Use the bulb type, voltage and wattage marked on the lamp or given in its instructions. A higher-wattage bulb than specified can overheat the lamp head and its wiring.
