Overview

In a working studio, a flashtube is a consumable — it's just a matter of when, not if. The Profoto 331514 exists to keep Compact 1200 Plus and Acute2 heads performing at spec when that moment arrives. Rated at 600 watt-seconds and built from uncoated quartz, it's the factory-matched replacement for those head platforms, meaning power output, discharge timing, and spectral characteristics should align with what your light meter and color workflow expect. For photographers shooting tethered with color-critical clients in the room, that consistency matters more than any spec number.

The uncoated quartz construction is a deliberate choice — it passes the full spectral range, including UV, which can interact with certain fabrics, reflective surfaces, and diffusion materials. Handling protocol during installation is the primary practical consideration: quartz is unforgiving of skin oils, which create thermal stress points and can cause premature failure. Beyond that, this is a straightforward maintenance component built to Profoto's tolerances. Keeping one in the kit bag is simply good studio practice — the alternative is a cancelled shoot while you wait on shipping.

Key Features

Even though they are designed to last tens of thousands of flashes, you may break one by accident. This is the replacement.

Pros & Cons

👍 Pros

  • Engineered specifically for Compact 1200 Plus and Acute2 heads, ensuring proper fit and rated output without modification.
  • Quartz construction handles the thermal cycling of high-powered studio strobe use better than standard glass tubes.
  • Uncoated design preserves full spectral output, useful for photographers who rely on UV transmission for certain materials or testing.
  • Having a spare on hand means a broken tube during a commercial shoot doesn't become a day-ending event.
  • Profoto-sourced replacement ensures the tube meets the original wattage and discharge specs the heads were designed around.

👎 Cons

  • Uncoated tube means UV passes through — not ideal if your workflow requires UV-blocking for skin tones or color-sensitive materials without additional filtration.
  • Single-use component with no user-serviceable indicator of remaining life; you're estimating replacement timing based on output behavior.
  • Requires careful handling during installation — quartz tubes are sensitive to skin oils, which can cause hotspots and premature failure if the tube body is touched.
  • Cost is non-trivial for what is essentially a consumable part in a high-volume studio context.

Frequently Asked Questions

It fits the Compact 1200 Plus and Acute2 heads — those specific models only. Don't assume cross-compatibility with other Profoto heads like the D1 or B-series; the geometry and socket type differ.
No — this is the uncoated version. That means full UV output passes through, which matters if you're using UV-reactive materials or certain diffusion fabrics. If your modifier or workflow requires UV-blocking, Profoto offers coated variants.
Look for inconsistent color temperature, visible darkening or devitrification of the quartz tube, or recurring misfires that persist after checking modeling lamp and capacitor health. A degraded tube is usually visually obvious up close.
Yes, but treat it as a bench task, not a field swap. Allow the head to fully discharge and cool, handle the tube only by its ceramic ends — skin oils on quartz shorten tube life — and refer to Profoto's service documentation for your specific head model.
Yes. A fresh tube in good working condition will bring output back in line with spec. If color drift or inconsistency persists after replacement, the issue likely lies elsewhere — capacitors, IGBT, or sync circuitry.
