Duralamp halogen bulbs sit in the “Traditional sources – Halogen lamps” part of the Duralamp range. They’re positioned as classic, high-CRI light sources that are:

inexpensive,
easy to use and widely compatible,
and still valued where LED cannot yet copy the same beam, size or dimming behaviour.

Within that family Duralamp offers both G9 bi-pin capsules and R7s linear lamps, covering compact decorative fittings and floodlights. All of them share the same promise printed in Duralamp’s own documentation: excellent colour rendering, low cost, wide diffusion and easy to use Halogen lighting is still used in projects where teams need warm colour rendering, instant brightness and stable dimming without committing to a fixture change. For applications that demand controlled optics — jewellery counters, boutique retail, focused display lighting — designers often choose specialised, high-definition ranges such as blv halogen lamps. Budget-conscious refurbishments and public-sector facilities, on the other hand, often prioritise ease of replacement and predictable stock availability, which makes bemko halogen lamps a practical fit. Commercial interiors looking for uniform, dependable output across multiple rooms or sites frequently include the balanced, general-purpose lines from bellight halogen lamps. Where the environment is more demanding — workshops, utility rooms, technical spaces — planners typically reinforce their specifications with rugged, long-service models from as schwabe halogen lamps to ensure stable operation under continuous use..

Construction and Technology of Duralamp Halogen Bulbs

All Duralamp Halogen Bulbs are based on tungsten-halogen technology:

Tungsten filament – a coiled filament runs at very high temperature, producing bright warm-white light with Ra≈100 colour rendering. Duralamp’s G9 and R7s datasheets explicitly quote Ra 100.
Halogen gas fill – a small amount of halogen (e.g. iodine/bromine) in an inert gas enables the halogen cycle, which redeposits evaporated tungsten on the filament instead of the glass. This keeps the capsule clear and lets the filament run hotter and more efficiently than in normal incandescent lamps.
Quartz / hard-glass envelope – compact, high-temperature glass around the filament; G9 versions are described as extremely compact mains-voltage halogen lamps with UV-stop quartz glass.
Standard bases –
- G9 bi-pin capsules for mains-voltage decorative fittings.
- R7s-15 double-ended linear lamps for floodlights and projectors.

Because halogen is an incandescent technology, all Duralamp halogen bulbs are naturally dimmable, with instantaneous “full light” and a pleasant warm-dim effect as you lower the level.

Range of Duralamp Halogen Bulbs – Capsules and Linear Lamps

Duralamp Halogen Bulbs – G9 Bi-Pin Capsules

The G9 line is designed as a mains-voltage capsule for compact luminaires:

Example model AG9-42 HALOGEN BIPIN:

These Duralamp Halogen Bulbs are the direct replacement rods for standard 78 mm and 118 mm R7s floodlights used on façades, yards and interior uplighters.

Performance Characteristics of Duralamp Halogen Bulbs

From Duralamp’s datasheets and reseller specs you can extract very concrete planning values:

Colour rendering
- CRI (Ra) = 100 on official halogen G9 and R7s data.
- This is as good as it gets for colour fidelity – ideal for wood, textiles, food, skin tones and artworks.
Colour temperature
- Most Duralamp Halogen Bulbs sit around 3000 K (some reseller G9 models at 2700 K).
- 3000 K gives a warm but slightly “crisp” white, perfect for hospitality, retail and living spaces where you want comfort plus clarity.
Luminous efficacy
- Example: 120 W R7s → 2,220 lm ≈ 18.5 lm/W;
- 18 W G9 → 205 lm ≈ 11–12 lm/W (very compact light source, not optimised for lm/W).
- That’s better than old incandescent, but of course far below modern LED – exactly why Duralamp positions halogen as a legacy/specialist source now.
Lifetime and switching
- Typical 2,000 h rated life for halogen G9 and R7s series, with up to 15,000 switching cycles quoted on the G9 datasheet.
Dimming and response
- All halogen models: instantaneous full light (trigger time <0.2 s) and warm-dim behaviour on standard dimmers.

Applications for Duralamp Halogen Bulbs

Because the range is compact – G9 capsules and R7s rods – the typical use-cases for Duralamp Halogen Bulbs are very clear:

Decorative and General Indoor Lighting

G9 capsules in:
- glass and crystal ceiling lights,
- wall luminaires,
- mirror and bathroom fittings (where rated for halogen),
- multi-arm chandeliers and small pendants.

Here you rely on:

tiny source size,
warm, high-CRI light,
and simple retrofit in 230 V G9 lampholders.

Accent and Retail Lighting

G9 halogen Duralamp bulbs are often used as hidden sources inside small spots or design luminaires to highlight surfaces and merchandise without visibly “bulky” lamps.

Floodlights, Uplighters and Façade Lighting

R7s Duralamp halogen tubes serve as the lamp in:
- yard and building floodlights,
- sign and banner projectors,
- interior floorstanding uplighters,
- small sports or parking area lights.

These installations benefit from the high lumen output, slim linear form and full dimming of the R7s Duralamp Halogen Bulbs.

How to Choose Duralamp Halogen Bulbs for a Project

Treat Duralamp Halogen Bulbs selection like a quick engineering step, not just “same wattage as before”.

1. Lock in base, length and voltage

For capsules: G9 base, 230 Vac only – check that your luminaire really uses G9 and not G4/GU10.
For linears: R7s-15, 78 mm or 118 mm – measure your lamp or check the fitting spec; length must match exactly

2. Respect luminaire wattage and temperature limits

Always read the maximum lamp wattage on the fitting.
Never exceed it – halogen runs hot and over-wattage can overheat wiring, reflectors and glass.
In tight decorative fittings, consider the lower-watt G9 options (e.g. 18–28 W) to reduce heat while keeping the same look

3. Choose brightness and number of lamps

For G9:
- Small fixtures or multiple-lamp chandeliers: 18–40 W Duralamp Halogen Bulbs are often enough.
- Single-lamp luminaires in larger rooms may justify 40–60 W, assuming the fixture allows it.
For R7s:
- Balcony / small façade: 80–120 W linear.
- Larger walls/yards: multiple 120 W or higher-power R7s projectors as defined by your lux targets.

4. Keep colour temperature consistent

Most Duralamp halogen is 3000 K; some G9 versions are 2700 K.
In one visual zone, pick a single CCT and stick with it so the room doesn’t look patchy.

5. Plan operating hours and maintenance

At ~2,000 h lifetime, a halogen lamp used 10 h/day reaches its rated life in ~200 days.
High-use circuits (shops, façades running all evening) benefit from group relamping and small spare stock of the relevant Duralamp SKUs.

Safety, Standards and Compliance of Duralamp Halogen Bulbs

Duralamp publishes quite detailed standards information for its halogen range:

Product standards – G9 and R7s halogen lamps are declared compliant with CEI EN 60432-2 (safety of halogen lamps) and CEI EN 55015 (EMC for lighting).
EU directives and regulations – the AG9-42 G9 halogen lists conformity with Ecodesign, RoHS, RAEE, EMC, Low Voltage Directive and the newest energy-labelling rules.

Practical safety tips on site with Duralamp Halogen Bulbs:

Let lamps cool fully before touching; both G9 and R7s get very hot.
Avoid touching the clear glass with bare fingers; clean with a dry lint-free cloth if you do – fingerprints can create hot spots and reduce life.
For R7s floodlights, check that the safety glass and gasket of the luminaire are intact before relamping.
Only use Duralamp halogen rods in fittings designed for halogen; do not retrofit them into enclosed housings meant only for LED.

Duralamp itself notes that halogen technology is “now totally replaceable by more efficient LED models”, so in new designs you should use halogen only where its specific strengths are required.

Wholesale and Project Use of Duralamp Halogen Bulbs

From a procurement point of view, Duralamp Halogen Bulbs work best as a small, standardised sub-range inside a wider Duralamp portfolio:

Define a core list:
- 1–2 main G9 wattages (e.g. AG9-42 18 W + a 40/60 W type) for decorative fittings.
- 80 W and 120 W R7s-15 in both 78 mm and 118 mm lengths for standard floodlights.
Order strictly by Duralamp code (AG9-42, 01982-ES, 01983-ES etc.) so replacements always match wattage, length, lumen output and colour exactly.
Combine them with Duralamp LED replacements in the same catalogue for the rest of the building – LED where efficiency and lifetime matter most, and Duralamp Halogen Bulbs only in the fixtures that truly rely on halogen’s tiny source size, perfect CRI and warm-dim behaviour.

Used deliberately like this, Duralamp Halogen Bulbs become a focused tool in your lighting toolkit rather than random legacy stock – ideal for keeping key G9 and R7s luminaires performing exactly as their optics and design intended.
