Is the Marelux Artemis 3000 RMT bright enough to be a primary underwater video light?
Yes for macro and close-to-medium subjects; its 4500-lumen white output and 120° flood produce clean, even illumination. For wide scenes or strong ambient light, many shooters pair two identical video lights for more even edge-to-edge coverage.
What batteries does it use and how long does it run?
It uses two 18650 Li-ion cells (3.7V). With quality, high-drain cells you can expect roughly 60 minutes at full white output, longer at reduced levels. Charge cells in a reputable external charger and carry a spare set for multi-dive days.
What does “RMT” mean—will the remote shutter work with my housing?
RMT refers to the light’s remote-shutter mode. When paired with the Marelux Remote Shutter Module (model 42510) on compatible Marelux housings, you can half-press to focus and fully press to trigger the camera. It isn’t a universal remote; check your housing’s compatibility before ordering the module.
Can I use this light for still photography or only for video?
It’s excellent as a focus/aiming light and for constant-light macro stills. For fast-moving subjects or wide scenes, a strobe still freezes motion and delivers higher peak brightness. Many hybrid shooters use the Artemis 4500 RMT for video and focusing and strobes for stills.
What mounting and accessories do I need to get started?
The light uses a standard 1″ ball mount, so you’ll want an arms-and-clamps set and a sturdy tray for compacts or mirrorless rigs. Consider a second matching light for wide-angle balance, red mode for night/macro behavior, and fluorescence filters if you plan blue-light/UV-style creative work.
