How to find the right Halogen Bulbs AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Halogen Bulbs
- Base type
- Identify the exact base: GU10 (twist-lock, line voltage), GU5.3 on MR16 (bi-pin, usually 12 V), G9 (loop pin), G4 (small bi-pin), R7s (double-ended linear) Several halogen bases look similar but are not interchangeable.
- Voltage
- Match 12 V low-voltage lamps to transformer-fed fixtures and 120 V/230 V lamps to line-voltage fixtures A line-voltage lamp in a low-voltage socket won't light, and the reverse burns out instantly.
- Beam angle (reflector lamps)
- Narrow spot for accent lighting, flood for general downlighting Beam angle changes the look of the lighting as much as wattage does.
- Wattage limit
- Do not exceed the fixture's labelled maximum wattage Halogen lamps run very hot.
Brands that matter
- Ushio: Specialist halogen and stage lamps.
- Philips: Broad halogen replacement range.
- Sylvania (Ledvance): MR16, PAR and linear halogens.
- Eiko: Specialty and replacement halogen lamps.
- Bulbrite: G4, G9 and JC-type capsules.
What to avoid
- Touching the quartz glass with bare fingers, because skin oil causes hot spots and early failure
- Open-face lamps in fixtures that require a front cover glass
- Assuming an LED MR16 will work on an old halogen transformer without checking compatibility
