Overview

The Profoto 331523 D1 500/1000 Replacement Flashtube is the manufacturer-specified part for restoring full functionality to Profoto D1 series monolights. Flash tubes are consumable components — while they are engineered to last tens of thousands of flashes, they eventually degrade or can be damaged during transport and demanding shoot environments. When that happens, this 1000Ws-rated replacement tube slides directly into both the D1 500 and D1 1000 units, bringing them back to factory output levels.

Using a genuine Profoto flashtube rather than a third-party alternative ensures that your D1 monolight maintains the precise color temperature and flash consistency that the system was calibrated around. This matters particularly for photographers who work with multiple D1 heads and rely on uniform output across their lighting setup. The compact packaging measures roughly 14 x 9 x 9 cm, and installation is a straightforward process that experienced users can complete on their own. For any studio relying on Profoto D1 lights as workhorses, keeping a spare 331523 tube on hand is a practical safeguard against unexpected downtime during shoots.
