Sekonic L-858D Modules: Godox vs Broncolor

Quick answer

Choose the Sekonic RT-GX if you use Godox flashes; pick the RT-BR for Broncolor studio lights. Both modules replace the factory radio board inside the L-858D and share the same physical design.

Trade-offs at a glance

• Godox RT-GX: If you already own Godox flashes or plan to build a Godox-based kit, this module gives you direct triggering from the meter. The 32 channels and 16 groups cover most location and studio setups.
• Broncolor RT-BR: If your studio runs Broncolor packs or monolights, the RT-BR provides dedicated address management (99 studio addresses, 40 lamp addresses) and a 30 m / 100 ft range. No extra trigger needed.
• Compatibility note: Neither module works with the other brand's flashes. You cannot mix Godox and Broncolor triggering through the same module. If you switch brands later, you buy the other module. Buy the module that matches your current flash system.
