Keep the mounting parts separate from the power kit
The 2500F head package includes battery and charging equipment. It leaves the tray and grip to your existing or separately chosen Flex-Connect setup.
A 2500F head for building or extending a rig
The SeaLife Sea Dragon 2500F light-head package supplies a 2500-lumen underwater photo/video light with its battery and charging equipment. It does not include a tray or grip. The selected head package is SL6712.
Who this suits
It is a candidate if you already have a compatible Flex-Connect mounting setup, or want to choose the tray and grip separately. The phrase light head describes the mounting-package scope here; it does not mean the battery and charger have been removed from the listed package.
Continuous light and beam coverage
The three listed brightness settings are full, half and quarter power. The light is specified at 5000 K with a Color Rendering Index of 90. Beam coverage is listed as 120 degrees in air and 90 degrees underwater, so use the underwater figure when planning coverage in water.
Power and mounting
The retained description names a removable 25 Wh lithium-ion battery and charging tray. The head mounts into the Flex-Connect system. Check the actual tray, grip or arm connection in your existing rig rather than assuming the mounting hardware is included because it appears in a family setup picture.
What to compare
Match 2500F and the SL6712 head package when comparing another offer. A package with a tray and grip is a different purchase scope, even if the light output is the same. The useful checks are continuous output, beam coverage and the mounting parts still needed.
