Profoto Flash Tube for D1 500 and 1000 Monolights

Purpose-built replacement tube

The Profoto flash tube is a direct replacement component for D1 500 and D1 1000 monolights. It restores the original output and colour performance of those heads without requiring any modification or adapter. Professional photographers and videographers who rely on consistent D1-series lighting use it to maintain their existing kits.

Practical limits of the D1 platform

The tube operates only within the electrical and thermal design of the D1 500 and 1000 units, so its recycle speed and maximum output are fixed by those monolights. It cannot increase power beyond the head’s rating, nor can it alter the colour stability that the D1 circuitry already governs. Users needing shorter flash durations or higher peak power must move to a different monolight system.

Upgrades from a degraded or failed tube

This part replaces a worn, cracked or colour-shifting tube that has lost output consistency or recycle reliability. The jump is worth it when the original tube shows visible damage, inconsistent exposure frame-to-frame, or a measurable drift in colour temperature that post-processing can no longer correct cleanly. It does not add new capabilities to the D1 heads.
