What owners report
Emisar D4V2 21700
- ✓More thermal mass than the 18650 version — turbo lasts meaningfully longer
- ✓Substantially more capacity from the 21700 cell
- ✓Same configure-to-order emitter, tint, material and switch menu
- ✓Anduril, with aux LEDs under the optic
- ✓Long-term owners report excellent build and no reliability problems
- ✗Noticeably larger and heavier than the 18650 version
- ✗No onboard charging on most configurations
- ✗Anduril's configuration menus are bewildering at first
- ✗Ordering means intl-outdoor with long shipping times
- ✗Still gets hot on turbo, just less quickly
Acebeam Rider RX
- ✓High-CRI Nichia 219F in an AA/14500 light
- ✓Bolt-action fidget clip that some owners find genuinely calming
- ✓Type III hard-anodised aluminium with good heat dissipation
- ✓1,000 lumens from a widely available cell format
- ✓Rated 4.5 out of 5 by a reviewer despite the regulation criticism
- ✗Output isn't regulated on 14500 — it dims as the cell drains
- ✗Every mode uses PWM, though it's well implemented
- ✗Forward-clicky tail makes mode changes awkward with the light on
- ✗Longer than most of its direct competition
- ✗Not enough texture for wet or gloved hands, and charging is slow
