The Broncolor Flash Tube (MPN: 34.360.00) is a professional-grade replacement component designed specifically for photographers using the Siros 400 and Siros 800 monolight systems. It provides the essential light output required for consistent color temperature and intensity, ensuring that your lighting rig performs exactly as it did when brand new. While it is an essential maintenance item for high-volume studio work, users should exercise caution during installation to avoid touching the glass with bare hands, which can degrade the component's lifespan.

No, this specific flash tube is designed specifically for the AC-powered Siros 400 and 800 models.
Replace it when you notice a significant drop in power, inconsistent flash duration, or if the glass shows visible signs of blackening or physical cracks.
No, you should avoid touching the glass with bare skin as oils can cause uneven heating and premature failure of the quartz envelope.
While it can be performed by the user, you must follow all safety instructions regarding capacitor discharge. If you are uncomfortable handling high-voltage equipment, contact a professional technician.
The lifespan depends on the power settings used; however, with proper care, it is rated for a high volume of professional-grade flashes.
Ensure the tube is fully seated in the socket and that the trigger lead is properly connected.
Verify that the tube is clean and free of fingerprints or dust, and confirm the light head is set to the correct power mode.
This is often a sign of natural aging or overheating; replace the tube to maintain light quality.
To install the flash tube, ensure the Siros power unit is completely powered off and disconnected from the AC power source. Wait at least 15-20 minutes for the internal capacitors to discharge and the tube to cool down. Carefully remove the old tube, taking note of the mounting clips. When handling the new flash tube, use a clean, lint-free cloth or cotton gloves; oils from your fingertips can create hot spots on the quartz glass, significantly shortening the tube's lifespan. The tube should slide firmly into the socket. If you encounter resistance, re-verify the orientation before applying gentle pressure. Always clean the glass with a small amount of isopropyl alcohol if accidental contact occurs before firing the unit.
