The RMF60 Mini Ring Light Series features three LED zones that can be controlled independently. The RMF60 is designed for dark field applications and produces a highly focused, homogeneous light pattern. The 4WMD is a four-channel external driver developed for multi-wavelength lights. The 4WMD permits up to four individual wavelengths to be controlled independently of each other. This external driver includes Multi-Drive, which allows a single channel to drive LEDs in continuous operation or OverDrive strobe mode separate from the other channels. The RMF60-KIT comes with an RMF60 ring light and a 4WMD-100 external driver.
