What owners report
Emisar D4K
- ✓Configure everything: materials, emitters, driver, switch and accessories
- ✓Optional boost driver gives higher and better-regulated output
- ✓Auxiliary LEDs that owners single out for how good they look
- ✓Geometry works well for hands-free and helmet-mounted use
- ✓Light enough to wear on a helmet for hours
- ✗No USB-C charging and no reverse charging — the cell comes out
- ✗Rated 3,800 lumens with a real-world ceiling nearer 2,000
- ✗Not the right light for hours of sustained high output
- ✗Specifying a configuration is daunting if you don't know what you want
- ✗Ordering goes through a small-batch supplier with long lead times
Thrunite T3
- ✓Exceptionally bright for the size, with long projection from a small lens
- ✓Consistent fixed-focus beam with no dim spots or dead zones
- ✓Natural colour temperature — neither overly white nor blue
- ✓Good battery life from the 21700 with USB-C charging
- ✓Solid Thrunite build quality
- ✗The charge port sits opposite the power button and feels the same under a thumb
- ✗Ramping interface won't suit anyone who prefers discrete modes
- ✗No high-CRI option
- ✗Fixed focus, so no adjusting the beam
- ✗Throw is modest next to dedicated throwers
