What owners report

Sofirn LT1

  • ✓Continuously variable colour temperature from very warm to cool, plus a red channel
  • ✓Full Anduril, which is what makes the CCT mixing worth having
  • ✓Four 18650s give genuinely long runtime
  • ✓Good build: thick even anodising, no sharp edges
  • ✓The warm end preserves dark adaptation far better than a generic cool-white lantern
  • ✗The carry bail is squeaky and gritty in use
  • ✗The bottom cap is awkward to start on its threads because of a big stiff spring
  • ✗Four cells to buy, charge and keep matched
  • ✗Bulkier than a collapsible lantern for backpacking
  • ✗The later LT1S traded Anduril for an in-house UI — a step back, not forward
