The Broncolor Flash Tube 400/800 J for Siros L & Stelos 800 L is a premium, genuine OEM replacement light source engineered specifically for Broncolor’s mobile, battery-powered monolight family. When executing high-stakes commercial campaigns, lookbooks, or editorial productions on remote location sets across Hong Kong, an unexpected flash tube failure can completely disrupt a high-budget schedule. Carrying this specialized plug-in flash tube as a dedicated backup provides absolute contingency assurance, keeping your location crew fully operational with zero downtime.
Designed to effortlessly process heavy energy discharges, this flash tube supports both 400 J and 800 J power thresholds across the battery-operated Siros L (400 L / 800 L) series and Broncolor’s cutting-edge portable flagship strobe, the Stelos 800 L. It features Broncolor’s proprietary UV-absorbing coating, which filters out volatile ultraviolet wavelengths to lock in a rock-solid, professional 5500 K color temperature across the entire dynamic power range. This allows creators to seamlessly mix mobile flash output with unpredictable natural ambient daylight.
Note: This flash tube is specifically engineered for battery-operated mobile monolights (SKU 34.362.00) and is not compatible with mains-powered AC Siros or Siros S studio units.
