Compact, floody EDC thrower with a reflowed Luminus SFT-70 4000K 95 CRI emitter, excellent thermal regulation, and a flat sustained output after step-down.
Fireflies executed the Z1 design perfectly. The size is ideal for EDC, nearly identical to the Zebralight SC65c. It produces a fantastic flooder beam profile with a large hotspot and useful spill. It is highly practical for typical EDC tasks, close-range illumination, and occasional indoor use.

Recessed side switch - an improvement over previous Fireflies models for guarding against accidental activation. Reviewer swapped in an older-style button with a raised retaining ring for easier by-feel operation without a pocket clip.

📈 Runtime & Thermal Analysis
Turbo & Step-down: Output starts at 1,900 lumens. It undergoes a rapid step-down within the first minute to approximately 1,100 lumens, followed by a gradual decline until the 10-minute mark.
Sustained Output: By 10 minutes, output stabilizes completely, maintaining a perfectly flat 500 lumens for the remainder of the test.
Thermal Performance: Temperature peaks near 64°C during the initial step-down phase before stabilizing around 58°C to 60°C under sustained load.
