What Is the Difference in Battery Consumption of Speedlights in On vs. Off Mode?
A speedlight is a type of external flash used in photography, designed to provide additional lighting for better exposure. The power consumption of a speedlight varies significantly between “on” and “off” modes. In “on” mode, the unit is fully operational and consumes power consistently, while in “off” mode, it typically draws minimal or no current.
According to the American Camera Manufacturer’s Association, speedlights can still deplete battery life when in standby mode, although this consumption is significantly less than in active mode.
In “on” mode, a speedlight can draw up to several watts depending on its settings and current use. Functions like zoom, modeling lights, and communication with the camera via wireless technology can further increase consumption. In contrast, “off” mode implies inactivity, though some models may include a sleep feature that still uses a small amount of power.
A study by the Technical Image Press Association highlights that speedlights in standby could retain about 90% of their battery charge over extended periods, demonstrating efficient power management.
The battery life of a speedlight affects photographers by dictating how long they can shoot before needing replacements. It can restrict usage during events or extended shoots, leading to missed opportunities.
To optimize battery life, photographers should consider using speedlights only when necessary, turning them off during downtime. Reports from the Imaging Resources and other photography organizations recommend regularly checking battery health and using high-quality batteries.
Investing in speedlights with enhanced power-saving features can mitigate excessive energy consumption. Employing rechargeable batteries may not only be economical but also environmentally friendly.
