🏠 Home Lighting – Chandeliers, wall lights, ceiling fixtures in living rooms, bedrooms, dining rooms, studies, corridors
🛋️ Ambient Decorative – Hotels, cafes, bars, art galleries – anywhere requiring high CRI and warm atmosphere
🛍️ Commercial Display – Jewelry stores, clothing boutiques, museums, display cases (with track lights or spotlights)
🔦 Low‑Voltage Systems – 24V under‑cabinet lights, track lights, display case lights, RV/boat interior lighting
💡 Direct Retrofit – Replaces old incandescent or halogen lamps without changing the fixture
Do not touch the glass – Halogen bulbs operate at extremely high temperatures (over 300°C / 570°F). Oils from your skin can cause the quartz glass to crack. Always use clean gloves or a tissue when handling.
Install with power off – Turn off the power supply before replacing the bulb to avoid electric shock or short circuit.
Avoid sealed fixtures – Halogen bulbs need proper ventilation. Do not use them in fully enclosed luminaires; otherwise, lifespan will be drastically reduced and overheating may occur.
Protect from vibration – The filament is fragile when hot. Avoid heavy shocks during installation or transportation.
Keep away from flammables – Maintain at least 20cm (8 inches) distance from curtains, paper, fabrics, etc., while the bulb is on.
Dimmer compatibility – Use a dimmer labeled “suitable for halogen lamps” and ensure its minimum load does not exceed 40W.
24V version – Must be used with a stable 24V AC or DC supply (preferably a halogen‑rated transformer). Never connect directly to 110V or 220V.
Q1: Is this bulb dimmable?
A: Not
Q2: Why does the bulb get so hot?
A: Halogen lamps are thermal radiation sources – most of the energy is emitted as heat. This is normal. Do not touch the bulb while it is on, and always ensure adequate airflow around the fixture.
Q3: What is the difference between the 24V and 110V versions?
A: The appearance and dimensions are identical. Only the internal filament resistance differs. Please confirm your existing lamp voltage before ordering.
Q4: How long does this bulb last?
A: Average rated life is about 2000 hours. For example, if used 5 hours per day, it will last about 13 months. Avoid frequent on/off cycles and overvoltage to extend lifespan.
Q5: Is 460 lumens bright enough? What equivalent wattage?
A: 460 lumens is comparable to a traditional 40W incandescent bulb or a 5W LED. Thanks to the 360° beam and high CRI, the perceived brightness is very comfortable and natural.
Q6: Can I use it outdoors?
A: This bulb is not waterproof and is intended for indoor dry locations only. For outdoor use, please install it inside a weatherproof enclosure.
Q7: Is the product environmentally friendly?
A: Yes, it complies with RoHS standards and contains no harmful substances such as lead or mercury.
