Convoy S2+ Nichia 519A 4000K R9050 High-CRI 18650 EDC
Nichia 519A 4000K R9050 high-CRI emitter paired with an orange peel reflector produces a clean, artifact-free spot and soft spill. Dedoming reduces CCT to ~3000K and shifts tint rosy (~-0.0040 DUV).

17mm 5A constant-current buck driver provides flat, ripple-free current regulation on all mode levels with no detectable PWM.
Why this matters: Buck and boost drivers step down or step up voltage efficiently using switching inductors, maintaining flat regulated output as cell voltage drains rather than dimming progressively like FET/linear direct drives.
