The compact and powerful RM140-4Z Mini Ring Light is a low-angle ring light that works best for dark field ring applications. The light can also be used for radial illumination. The RM140-4Z series features an aluminum housing and is IP65 rated. The RM140-4Z has four zones, making it a quadrant light in which each individual zone can be controlled independently of each other. The 4ZMD-250 is an external driver that permits control of up to four separate light zones either independently or simultaneously, in any combination. The 4ZMD has independent intensity controls and built-in Multi-Drive™, allowing for a range to be set from 10%-100% for continuous operations or OverDrive™ strobe mode. The RM140-4Z KIT includes a RM140-4Z mini ring light and a 4ZMD-250 external driver.
