Elinchrom EL10232.1 ELB 500 TTL Unit (No Battery)

The Elinchrom ELB 500 TTL is a portable flash power pack built for photographers who need reliable, high-output lighting beyond the studio. Delivering 500 watt-seconds of power, it fires up to 400 full-power flashes on a single battery charge with a 2-second recycle time at maximum output, keeping pace with fast-moving portrait, editorial, and event shoots. Its standout capability is High Speed Sync at shutter speeds up to 1/8000th of a second, which allows photographers to overpower ambient light and shoot with wide apertures even in bright outdoor conditions—a critical advantage for on-location work.

The pack features two fully independent flash outlets with 7 stops of asymmetric power control, giving photographers precise ratio adjustments between connected heads without additional accessories. Active Charging lets the unit run on AC power while simultaneously recharging the battery, making transitions between location and studio seamless. The EL10232.1 is the pack unit only—Elinchrom's Li-Ion battery and compatible flash heads must be purchased separately or as part of the ELB 500 TTL To Go or Dual To Go kits. Despite the modular purchasing approach, this design allows photographers to scale their lighting system incrementally and pair the pack with the specific heads that suit their work.
