Replacement Flash Tube for Studio R2 300/400

The Flashpoint replacement flash tube is built for the Studio R2 300/400 flash head and fits Godox SK400II and SK300II units. It delivers 400Ws output at a stable 5600K colour temperature for accurate colour reproduction. Professional photographers and videographers who need a direct replacement for a failed or degraded tube will find this unit matches the original specification.

UV Coating and Rated Lifespan

The tube includes a UV coating and is engineered for well over 100000 flashes, with a well-maintained unit capable of exceeding 250000 flashes. This extended service interval reduces the frequency of replacements during intensive studio work. The consistent 5600K output is maintained across the rated lifespan, supporting reliable colour accuracy for portrait and product sessions.

Simple Direct Swap Installation

Installation is a direct swap inside the compatible flash head and requires no modifications to the housing or wiring. The tube seats into the existing mount, so the changeover can be completed in minutes. The main risk is contaminating the glass envelope; skin oils can create hot spots that shorten life, so the tube must not be touched with bare hands during fitting.

Questions about this item

How many flashes can the 400Ws tube deliver before it needs replacing?

The tube is engineered for over 100,000 pops and a well-maintained unit can exceed 250,000 flashes before replacement is required.

What limits continuous firing during a long session?

The 400Ws power rating and 5600K color consistency define the output ceiling; sustained full-power bursts will hit recycle-time and thermal limits first.

How hot or noisy does the flash head get when the tube runs all day?

The replacement tube itself is passive — it adds no fan noise or active heat — so any warmth or sound comes from the Studio R2 head's own cooling system.
