Toplux Halogen Bulbs cover the “classic” lamp types that still matter where LED is not yet a clean drop-in: low-voltage capsules for projectors and equipment, mains-voltage decorative bulbs, R7s linear lamps for floodlights, and MR16 reflector lamps for accent lighting. The brand focuses on simple, robust products that stay compatible with existing fittings and transformers, which is why you still see Toplux in shops, workshops and technical installations across Europe. On projects where you still need compact, high-intensity light with excellent colour rendering, halogen remains a useful tool. For everyday spot and accent replacements in shops and small interiors, distributors often rely on zext halogen lamps and installer-oriented vagner halogen lamps. Museums, galleries and projector-based applications that demand precise beams and stable colour frequently specify ushio halogen lamps, while control panels, signal points and technical fittings are commonly standardised on robust thorgeon halogen lamps. Retail and hospitality chains that want a recognised reference line across multiple sites usually complete their assortment with sylvania halogen lamps so light quality stays predictable from store to store.

Assortment of Toplux Halogen Bulbs

The Toplux Halogen Bulbs range is broad enough to cover most legacy and special-purpose luminaires:

Low-voltage capsules without reflector
- G4 and GY6.35 pins, typically 6 V, 12 V, 24 V, 20–100 W.
- Used inside spot heads, display fittings, projectors, dental/medical lights and small downlights.
MR11 / MR16 low-voltage reflector lamps
- 12 V, usually 20 W or 35 W, in 50 mm MR16 format, often sold in multipacks (e.g. 10× 20 W MR16 12 V).
- For retail spots, track lights, recessed accent lighting and small projectors.
Linear R7s halogen lamps
- 230 V 300 W R7s in 118 mm length, used in floodlights, security lights and narrow flood luminaires.
JD “stick” and capsule mains-voltage lamps
- JD 75 W BA15d and JD 150 W E11 clear lamps at 220–240 V for small architectural floods, shop lights and decorative fittings.
E14 and E27 retrofit bulbs
- E14 25 W candle clear and E27 72 W halogen classic bulbs with standard 230 V operation for chandeliers, wall fixtures and general household luminaires.

This structure means you can standardise on Toplux Halogen Bulbs for almost all conventional sockets in one project, instead of mixing brands per fitting.

Technical characteristics of Toplux Halogen Bulbs

Across the different shapes, Toplux Halogen Bulbs share several technical traits:

High luminous flux for compact size
- Example: a 6 V 35 W GY6.35 capsule delivers about 420 lm with 2700 K warm white, giving strong point output from a tiny source.
- A 72 W E27 halogen replacement bulb reaches around 1200 lm, roughly matching old 100 W incandescent lamps.
Colour temperature and CRI
- Most Toplux Halogen Bulbs sit in the 2700–2900 K range (warm white) with CRI close to 100, so colours look natural and skin tones remain accurate
Dimming behaviour
- Halogen is naturally dimmable; Toplux low-voltage and mains-voltage bulbs respond smoothly to standard leading-edge or trailing-edge dimmers without flicker or step changes, provided the circuit is wired for halogen
Rated life
- Typical lifetimes are around 2000 hours under nominal conditions for capsules and MR lamps, which is standard for decent halogen quality
Operating voltage
- Very low-voltage capsules: 6 V and 12 V for projectors and special devices.
- Low-voltage standard: 12 V and 24 V for MR16, G4 and GY6.35 in lighting fittings.
- Mains-voltage: 220–240 V lamps with E14, E27, R7s, BA15d, E11 bases for direct connection to line voltage.

Knowing these numbers helps you match replacements precisely and avoid overloading transformers or under-running lamps.

Materials and construction in Toplux Halogen Bulbs

Even with simple lamps, construction details matter:

Glass envelopes
- Low-voltage capsules use clear quartz or hard glass to withstand high temperature and pressure, with compact filaments to keep the light source small and intense.
- Retrofit E14/E27 bulbs use conventional bulb envelopes, but with reinforced stems and halogen capsules inside to increase efficiency over old tungsten lamps
Filament design
- Short, tightly coiled filaments in MR16 and capsule types enhance beam control when used with reflectors or optics.
Caps and bases
- Precision two-pin bases G4, GY6.35, GU4, GU5.3 ensure correct focal positioning in reflectors and projectors.
- Screw bases (E14, E27) and special caps (BA15d, R7s, E11) are dimensioned to IEC standards so Toplux Halogen Bulbs fit existing lampholders without mechanical issues.

The combination of proper glass, filaments and base accuracy is what separates a reliable halogen lamp from a cheap one that fails early or gives a distorted beam.

Typical applications for Toplux Halogen Bulbs

Different sub-ranges of Toplux Halogen Bulbs are tuned for distinct use cases:

Display and accent lighting
- MR16 12 V 20 W lamps with aluminium reflectors are classic choices for shop windows, product shelves and gallery spots where tight beams and warm colour are valued.
Technical and equipment lighting
- G4 and GY6.35 capsules in 6–24 V versions are common in projectors, medical or dental lights, microscopes and compact downlights
Flood and security lighting
- R7s 300 W lamps in 118 mm length power many classic outdoor floodlights on sites, driveways and sports courts.
Decorative and residential fittings
- E14 25 W candle bulbs and E27 72 W halogen classic bulbs are used in chandeliers, wall sconces and ceiling fittings where warm light and smooth dimming matter more than maximum efficacy.
Architectural and shop floods
- JD BA15d and E11 halogens at 75–150 W fill compact floodlights and display fittings that demand a very small bright source and precise reflector geometry.

If you map your fixtures by socket type, you’ll usually find that one or two Toplux Halogen Bulbs families cover most of them.

Performance and light quality of Toplux Halogen Bulbs

From a lighting-design perspective, Toplux Halogen Bulbs behave like classic halogen sources:

Colour rendering
- As thermal radiators, these lamps provide an almost continuous spectrum with CRI close to 100, making colours, textiles, artwork and food displays look true and saturated.
Beam control
- MR16 versions with aluminium reflectors produce defined spot and flood distributions, especially when combined with clear front glass, making them suitable for precise accent work.
Warm dimming
- All Toplux Halogen Bulbs shift to warmer tones as they are dimmed, mimicking candle-like ambience in restaurants, hotels and homes, without needing special LED drivers.
Instant response
- No warm-up, no driver delay: full output is available immediately at switch-on, which is valuable for security floods and equipment lights.

These behaviours are why many designers still keep halogen in mix for certain spaces, even when most general lighting is LED.

How to choose the right Toplux Halogen Bulbs

To avoid wrong orders and burned-out lamps, it’s worth following a step-by-step approach:

Start with the lampholder
- Identify the cap: E14 / E27 / G4 / GY6.35 / GU4 / GU5.3 / R7s / BA15d / E11.
- Check physical size and overall length (e.g. 118 mm for R7s, 11×44 mm for some GY6.35).
Confirm the voltage
- Look at the fixture label or the old lamp: 6 V, 12 V, 24 V or 220–240 V.
- Never mix 12 V and 230 V products – both safety and lamp life will be compromised.
Match the wattage and thermal limits
- Stay within the fitting’s maximum wattage; using a higher-wattage halogen in a small enclosed luminaire can overheat the fitting and shorten lamp life.
- For projectors and equipment, follow the exact lamp code and wattage recommended by the manufacturer.
Pick colour temperature and beam
- Most Toplux Halogen Bulbs are warm white, but some technical variants are slightly cooler (around 2900 K).
- For MR lamps, choose spot or flood angles appropriate to the distance and area you want to light.
Consider dimming and control
- If the circuit is on a dimmer, stick to dimmable Toplux Halogen Bulbs (most are), and check that the dimmer’s minimum load is met, especially on small circuits.
Standardise across the project
- Use the same Toplux references in all similar fittings in a zone; it simplifies relamping, stock keeping and ensures uniform appearance.

Procurement and logistics for Toplux Halogen Bulbs

For purchasing teams, Toplux is typically treated as part of the “conventional lamps” basket:

Categorisation
- On many professional platforms you’ll find Toplux under “Conventional Lamps”, with sub-categories for Toplux Halogen Bulbs, CFL, special lamps and fluorescent tubes, which makes filtering by technology straightforward.
EAN / stock codes
- Each lamp variant has its own EAN and manufacturer part number; using these instead of descriptive text avoids wrong items when multiple wattages or voltages exist for the same base.
Stock strategy
- High-usage items (e.g. MR16 12 V 20 W, E14 25 W candle, R7s 118 mm 300 W) are usually kept in depth onsite, while rare voltages (6 V, 24 V capsules) are stocked in smaller quantities and topped up via B2B distributors.

Having a clear internal list of “standard” Toplux Halogen Bulbs per site makes it far easier to switch from reactive emergency buying to planned, cost-efficient procurement.

Wholesale supply of Toplux Halogen Bulbs by Bank of Lamps

Bank of Lamps supplies the full Toplux conventional portfolio, with Toplux Halogen Bulbs as a dedicated category alongside CFL, special lamps and fluorescent tubes. That allows you to:

Build project-specific baskets across multiple Toplux technologies.
Filter by cap type, wattage, voltage and stock availability before committing to a specification.
Align EAN / MPN codes with your ERP so repeat orders are one-click instead of manual lookup

For mixed LED and conventional projects, this approach lets you treat Toplux Halogen Bulbs as a stable, predictable backbone for existing luminaires, while the rest of the lighting concept gradually migrates to LED at the pace that makes sense for your budget and technical constraints.
