Buying Guide: Key Purchase Considerations
- Base type and length: Most of these bulbs use R7S double-ended bases with 118mm or 4.6–4.7-inch lengths. Confirm your fixture’s socket style and space to prevent a tight fit or misalignment.
- Color temperature: 2700K warm white is common in these options, which suits cozy residential lighting, while some users may prefer brighter 2800–3000K if you need clearer task light.
- Lumens and beam angle: Higher lumens mean more brightness; 360° beams offer full area illumination. Choose based on the fixture’s purpose, such as floodlighting or accent lighting.
- Dimability: Some bulbs are listed as dimmable; ensure your dimmer switch supports halogen bulbs and the fixture’s compatibility to avoid flicker or color shifts at low settings.
- Price per bulb vs. pack size: Multipacks lower the per-bulb cost and simplify replacements in fixtures with multiple locations. Consider total project needs when choosing pack size.
- Environmental considerations: Most options claim no mercury and reduced UV/IR radiation, but verify any fixture-specific safety requirements and disposal guidelines for halogen lamps.
