Buying Guide

  • Voltage and Base Compatibility: Match the fixture’s voltage (12V AC/DC) and base type (G4, GU5.3, wedge/T5) to ensure a proper fit and electrical safety.
  • Light Color and Quality: Warm 2700K–3000K tones create inviting outdoor spaces; check CRI for color accuracy in landscaping features.
  • Wattage and Brightness: LED options deliver high efficiency at low wattage; halogen options may provide brighter, instant accents but consume more power.
  • Dimmer Compatibility: If you use dimmers, choose dimmable bulbs and compatible transformers; non-dimmable bulbs can flicker on dimmers or unstable power.
  • Installation Ease: Quick-clip or wedge-based designs reduce installation time; consider fixture clearance for larger bulbs.
  • Durability and Weather: Outdoor bulbs should withstand moisture and temperature variations; verify IP rating if exposed to the elements.
  • Maintenance and Longevity: LED bulbs typically offer longer life and lower maintenance than halogen bulbs, reducing replacement frequency.
