It seems like you're describing a set of strobes or flashes with specific features. Here's an overview based on the information provided:
Type of Strobes:
The strobes you mentioned are IGBT (Insulated Gate Bipolar Transistor) strobes. These are a type of electronic flash that uses IGBT technology for precise control over the flash output.
Power Source:
The strobes are powered by Lithium-ion batteries. Lithium-ion batteries are known for their high energy density, providing longer-lasting power compared to traditional batteries.
TTL (Through-the-Lens) and HSS (High-Speed Sync):
The strobes support TTL, which is a metering system that allows the camera to determine the correct flash exposure through the lens. HSS (High-Speed Sync) is also supported, enabling the flash to synchronize with high shutter speeds, useful for situations with bright ambient light.
Built-in Radio Receiver:
The strobes have a built-in 2.4GHz radio receiver. This feature allows for wireless communication and control, enabling the strobes to be remotely triggered and controlled by a compatible transmitter.
Compatibility:
The strobes are designed specifically for Canon and Nikon DSLR camera systems. This ensures seamless integration and communication between the camera and the strobes.
Size and Color:
The size is described as "standard," which implies a typical size for portable strobes. The color is mentioned as "grey," indicating the exterior color of the strobes.
In summary, the 5 TTL Lithium-ion-powered strobes you described are advanced lighting equipment with features such as IGBT technology, TTL metering, HSS capability, and built-in 2.4GHz radio receivers. They are designed for compatibility with Canon and Nikon DSLR camera systems, providing photographers with flexibility and control over their lighting setups.
