This has got a lot of use already to control my AD200s from my light meter. It speeds up workflow considerably especially when you don?t have to keep walking back to the camera to attach and detach the trigger. I am very happy with it

Plug and Play. Everything worked perfectly out of the box. The meter detected the card and I've been using it with no issue.

This product works like a charm. It makes using a light metter with high speed sync easy. No issues at all with product or shipping. Arrived a day earlier than promised.

I am having a hard time trying to download the firmware to upgrade my flash. If I can get it to work, I think it?ll be great asset to my lighting and camera set up.

I was able to work around not having this transmitter for years, but now it just works. It saves me time and make my work more streamlined. I don't need a separate remote to trigger the flash.

I will begin by telling you that it’s a great product. If you are using Flashpoint or Godox strobes, this is a must have product. When you are trying to balance your lighting this makes it easier and faster to determine the amount of light coming from each strobe. Before this unit was available I had put together a clumsy system that took a lot of time and effort to use. One thing the instructions, that comes with the unit, does not tell you is the Firmware must be level 17 for it to work.

Fantastic! This makes metering your Godox or Flashpoint strobes or speedlights so easy now. The Sekonic L-858D-U Light Meter just got a whole lot easier to use and is now actually fun to use when measuring light output. I no longer have to carry around a trigger around or constantly have to remove the trigger from the camera hot shoe! I am able to control all of my light groups power and modeling lights all from my light meter now! This a game changer! I would purchase again in an instant! Highly recommend!

Together with broncolor, we are proud to announce the Sekonic RT-BR transmitter module for the Sekonic L-858D-U (USA) Light Meters. This collaboration brings a fully integrated light metering workflow to broncolor users, making it possible for them to measure effortlessly, control, and analyze the characteristics of flash like never before.
Sekonic's mission is to enable image makers to craft great light in every image, and the Sekonic RT-BR simplifies the process. It helps you quickly dial in your lighting recipe to get to your final image with exacting precision.
Features
Full Radio Compatibility
Broncolor users will rejoice in being able to call upon all 99 Radio Studio Addresses (1-99), 40 Lamp Addresses (1-40, All) to remotely trigger their broncolor lights up to 100ft away. You can even wirelessly control the power of modeling lights as well.
Next Level Flash Analysis
Now Broncolor users can more easily measure the percentage of flash in their images to maintain the desired mix of ambient and flash. Measure flash duration as well to know how much stopping power your lights have to freeze the splash from their favorite product shot, or the pose of a ballerina.
