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
Which Profoto heads is the 331514 flashtube compatible with?
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.
Does this flashtube have any UV coating or color correction?
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.
How do I know when it's time to replace the flashtube rather than troubleshoot another component?
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.
Is installation something I can do myself on a shoot?
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.
Will replacing the flashtube restore original color temperature and power consistency?
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.
