SOWIN GXEC — U-Shape Quartz-Glass Xenon Flash Tube Built for stable ignition, high peak intensity, and flash-to-flash repeatability in professional photographic strobe systems. Optical fit — U-shape geometry matches reflector cavities and tight optical layouts for better coverage. Repeatability under high repetition — reduces misfire and brightness drift during long shooting sessions. Anti-aging control — mitigates early blackening and lifetime collapse within a defined operating window. Reliability Boundaries (Engineering Definition) Lamp structure + arc-length matching + trigger coupling stability + energy / frequency / duty-cycle window + thermal management Procurement sign-off ready: engineer-reviewed parameter sheet + replacement checklist (custom dimensions / electrical ranges / structures supported).
