Pros & Cons
👍 Pros

- Allows for precise control over the power level of connected lights, enhancing creative lighting possibilities.
- Supports a wide range of Elinchrom radio channels (1 to 20) and groups (G1 to G4 + ALL), providing flexibility in complex setups.
- Also compatible with Phottix lighting systems, supporting channels (1 to 4) and groups (A to D).
- Designed as a transmitter module for the L-858D-U light meter, consolidating metering and triggering into one device.
👎 Cons
- Requires the Sekonic L-858D-U light meter for operation, meaning it is not a standalone triggering device.
- Compatibility is limited to Elinchrom and Phottix systems, which means it cannot trigger other brands of strobes.
- The specific range of the radio transmission is not provided, which could be a factor for large studios or outdoor shoots.
- The module is primarily for triggering and power control, and does not mention advanced features like HSS or TTL support.
- Being a module, it is an additional purchase and installation for the L-858D-U, adding to the overall cost of a triggering solution.
