AS Schwabe halogen bulbs are not “generic household lamps” – they’re rugged R7s halogen rods built for construction sites, industrial yards, façades and professional worklights. The company is a German manufacturer focused on power distribution, cables and work lighting; its halogen range is tailored to match that profile: floodlights and site lights that must survive rough handling and long operating hours.

In practice, AS Schwabe Halogen Bulbs are used to:

keep existing halogen floodlights and worklights in service,
deliver very high lumen packages (up to tens of thousands of lumens) from compact R7s fixtures,
give instant-on, full output with perfect colour rendering on construction or industrial sites.

Construction and Durability of AS Schwabe Halogen Bulbs

AS Schwabe halogen rods are designed as trade and industry-grade components, not disposable consumer lamps:

R7s double-ended design
All the well-documented AS Schwabe Halogen Bulbs are linear R7s tubes: glass rod, contact caps at both ends, clamped into spring-loaded holders in floodlights and worklights.
Tungsten–halogen capsule
A coiled tungsten filament sits inside a high-temperature glass envelope filled with halogen gas. The halogen cycle redeposits evaporated tungsten back on the filament, keeping the glass clearer and allowing higher filament temperature than classic incandescent rods.
Shock-resistant build
Product descriptions explicitly call these halogen rods “stoßfest” (shockproof) and suitable for “höchste Beanspruchung” (highest stress) – exactly what you want in construction floodlights that are constantly moved, bumped and heated/cooled. Halogen lamps still play an important role in projects where warm colour tone, instant output and smooth dimming remain part of the lighting brief. For broad maintenance and multi-site replacement programs, teams often start with the dependable, long-established ranges from ge halogen lamps, which offer predictable sizing and stable performance. When designers need versatile options for compact interiors, retail details or hospitality accents, they frequently rely on the installation-friendly assortment of duralamp halogen lamps. Projects that demand tighter beam precision or more controlled light distribution commonly integrate specialised series like blv halogen lamps. For cost-driven refurbishments and public-sector facilities, procurement teams often include practical, service-ready replacements such as bemko halogen lamps to keep maintenance predictable. And in commercial settings where uniform light output and consistent colour rendering are priorities, planners frequently complete their specifications with the steady, well-balanced lines from bellight halogen lamps.
Professional quality and compliance
AS Schwabe markets these as “Handwerker- und Industriequalität” (craftsman and industrial quality) and notes conformance to EU norms, with 230 V / 16 A technical data aligned to standard power circuits.

In short: AS Schwabe Halogen Bulbs are engineered as consumables for tough work environments, not decorative living-room bulbs.

Assortment of AS Schwabe Halogen Bulbs for Floodlights and Worklights

The range is compact but very targeted: almost everything revolves around R7s halogen rods in a few key lengths and wattages.

Short AS Schwabe Halogen Bulbs – 78 mm R7s

For compact floodlights and worklights you’ll see:

120 W, 78 mm R7s
- Approx. 2,300 lm light output
- Warm white around 2800 K
- Designed as a replacement lamp (“Ersatz-Lampe”) for small halogen floodlight

These AS Schwabe Halogen Bulbs fit narrow projectors around garages, small yards, entrances and portable site lights with 78 mm holders.

Medium AS Schwabe Halogen Bulbs – 118 mm R7s

This is the workhorse size for typical 400 W site floodlights:

400 W, 118 mm R7s
- 8600 lm, 230 V
- Warm white 2800 K
- Energy class C (older EU label)
- Explicitly sold “for halogen floodlights”, for highest stress, long service life, shock-resistant, trade & industrial quality.

These AS Schwabe Halogen Bulbs are exactly what goes into the manufacturer’s own 400 W halogen floodlights/construction spotlights, which are advertised for worksite use.

High-output AS Schwabe Halogen Bulbs – 189 mm R7s

For large projectors and industrial/sports lighting, AS Schwabe offers long and powerful rods:

1000 W, 189 mm R7s
- Approx. 18,000 lm
- 2800 K warm white
- 230 V / 16 A
- Again marketed for heavy-duty use, long life and shock resistance

Catalogue and marketplace listings also group AS Schwabe Halogenbrennstäbe (halogen fuel rods) from around 130 W up to 2000 W, with luminous flux from 2,300 lm up to ~35,000 lm, all under the R7s format for floodlight applications.

Across these versions, AS Schwabe Halogen Bulbs give you a clear ladder: 120 W → 400 W → 1000 W → up to 2000 W, all using standard R7s holders.

Performance Characteristics of AS Schwabe Halogen Bulbs

From the published data you can derive very concrete planning values:

Warm white colour temperature
Both the 400 W (118 mm) and 1000 W (189 mm) halogen rods are specified at 2800 K – a warm, slightly “cleaner” version of traditional incandescent that works well outdoors, on façades and in work areas without looking cold.
High luminous flux
- 120 W / 78 mm → ~2,300 lm
- 400 W / 118 mm → 8600 lm
- 1000 W / 189 mm → 18,000 lm
- Top-end 2000 W rods → up to 35,000 lm according to multi-offer product data.
This is why AS Schwabe Halogen Bulbs are still interesting: you can push huge light output through relatively small projectors.
Excellent colour rendering
Being tungsten-halogen, these bulbs effectively offer very high CRI with a continuous spectrum – ideal where you need natural colour impressions on machinery, building surfaces or vehicles.
Instant full brightness & dimmability
Unlike discharge lamps, AS Schwabe Halogen Bulbs turn on at 100% with no warm-up time and are naturally dimmable on suitable dimmers or switching levels. That’s still attractive for temporary lighting, events and sites where you constantly move and re-aim lights.
Rated for tough operation
Product descriptions emphasise long service life under high mechanical and thermal stress – not “ultra-long-life” in hours, but robust against shocks and high switching frequency in construction and industrial use.

Typical Applications for AS Schwabe Halogen Bulbs

Because the entire visible range is R7s-based, AS Schwabe Halogen Bulbs naturally sit in a few clear application clusters:

Construction and Renovation Sites

Portable halogen tripods and stand-mounted projectors.
Floodlights on scaffolding, site fences and temporary masts.
Worklights for trades such as painters, plasterers, electricians and installers.

The “Handwerker- und Industriequalität” plus shock resistance directly targets this audience.

Industrial and Logistics Areas

Yard lighting around depots and warehouses.
Loading ramp and façade floodlights that are switched for specific operations.
Temporary rigs for maintenance shutdowns or night work.

Here, AS Schwabe Halogen Bulbs are often used to keep older floodlights in service until an LED conversion is justified.

Sports and Event Lighting

Training pitches, smaller courts and improvised sports grounds with legacy halogen projectors.
Temporary event lighting rigs where instant-on, good colour and simple dimming still matter more than ultimate efficiency.

The 1000–2000 W variants in particular are aimed at large-area floodlighting tasks

How to Select AS Schwabe Halogen Bulbs for Your Floodlights

When you specify AS Schwabe Halogen Bulbs, treat it like a small engineering decision rather than just wattage swapping.

1. Confirm the R7s Length and Wattage Window

Measure your existing rod or check the luminaire label:
- 78 mm – compact projectors (usually 120–150 W).
- 118 mm – the most common halogen floodlight length (often 300–400 W).
- 189 mm – large projectors around 1000 W and more.
Never attempt to force a different length into a holder – R7s fittings are built to precise dimensions.

2. Check Fixture Ratings and Circuit Capacity

Read the maximum lamp wattage on the floodlight label; AS Schwabe halogen projectors themselves are sold with clear wattage ratings (e.g. 400 W or 1500 W).
Match or go slightly below that value; do not exceed it.
For 1000–2000 W rods, ensure the circuit, plug and extension cables are rated for the corresponding current (e.g. 230 V / 16 A for 1000 W).

3. Define the Lighting Task

Short-range work area lighting
- 120–400 W AS Schwabe Halogen Bulbs usually suffice for room-sized or small yard areas.
Medium-range façade or yard lighting
- 400–1000 W rods in 118–189 mm projectors.
Large-area or sports-level lighting
- Consider 1000–2000 W variants where the luminaires are built for them.

Link the wattage choice to the distance and area size rather than simply picking the biggest available lamp.

4. Consider Duty Cycle and Maintenance Strategy

For short, intense use (evenings, occasional night work), halogen’s lower efficiency is less critical; its simplicity and instant full brightness are advantages.
For long-duty circuits (yard lighting on for many hours nightly), it’s often better to:
- keep AS Schwabe Halogen Bulbs as short-term or backup solution,
- plan a medium-term upgrade to LED floodlights,
- and calculate how many halogen rods per year you’ll need to stock based on ~2000 h typical life.

Safety, Standards and Procurement of AS Schwabe Halogen Bulbs

Safety and Handling

With AS Schwabe Halogen Bulbs, most safety issues come from heat and mechanical stress:

Let floodlights cool completely before replacing rods – R7s lamps run extremely hot at 400–1000 W.
Avoid touching the glass with bare fingers; if you do, clean the rod with a lint-free cloth to remove oils that can create hot spots.
Check that the R7s contacts clamp firmly on both ends; loose fit causes arcing and overheating.
Make sure safety glass and seals on the floodlight are intact – AS Schwabe’s own 2000 W projectors, for example, use dustproof die-cast housings with safety glass for IP protection and user safety.

Standards and Quality Positioning

AS Schwabe explicitly states that its halogen rods conform to EU norms and are designed for professional use – “Handwerker- und Industriequalität, stoßfest, für höchste Beanspruchung”.
That means you can confidently specify AS Schwabe Halogen Bulbs in professional tender documents as compliant replacements for existing R7s equipment.

Procurement Strategy

For wholesalers, contractors and facility managers, AS Schwabe Halogen Bulbs work best as a small, standardised subset:

Keep a core ladder of R7s rods in stock:
- 120 W / 78 mm (small projectors)
- 400 W / 118 mm (standard construction floodlights)
- 1000 W / 189 mm (big projectors),
- plus any 1500–2000 W types your installed base uses.
Order strictly by manufacturer article numbers (e.g. 46010 for the 120 W rod, 46012 for the 400 W, 46101 for the 1000 W) so replacements always match wattage, length, lumen output and colour temperature.
Combine them with AS Schwabe’s own LED worklights and floodlights in the same projects, using halogen only where you really need its high lumen density, warm light and simple behaviour as part of the lighting concept.

Used this way, AS Schwabe Halogen Bulbs aren’t just legacy consumables – they’re a focused, professional tool for heavy-duty floodlighting, chosen deliberately where halogen’s strengths still match the job.
