Q: Is the Pro-B3 compatible with non-Profoto light modifiers?
A: The Pro-B3 uses Profoto's bayonet mount and works natively with all Profoto light shapers. Third-party modifiers require adapter rings, though this may limit AirX wireless functionality and TTL metering accuracy.

Q: What's the warranty coverage for location damage?
A: Profoto provides a standard manufacturer warranty covering defects. Environmental damage from location shoots (impact, water, sand ingress) typically requires optional extended coverage. Contact your authorized dealer for specific warranty terms and available protection plans.

Q: How does the Pro-B3 differ from the Pro-D3 studio monolight?
A: The Pro-B3 runs on rechargeable batteries for location mobility, while the Pro-D3 requires AC power for continuous studio operation. The Pro-D3 offers faster recycling (0.01-0.5s) and is optimized for high-volume studio production rather than outdoor portability.

Q: Does Freeze mode affect color consistency across power settings?
A: The Pro-B3 maintains 6,300K ±100K color temperature consistency in all three modes (Eco, Boost, Freeze). However, Freeze mode prioritizes ultra-short flash duration over absolute color stability, with minor shifts possible at extreme power settings.

Q: What maintenance is required for battery longevity?
A: Store batteries at 40-60% charge in climate-controlled environments. Cycle batteries fully every 30 days if unused. Replace flash tube after approximately 100,000 flashes or when color temperature shifts beyond ±200K from baseline readings
