How we calculate scores →About this gear
Sea Dragon 2500F SL6712 is the light-head package with a 25 Wh rechargeable battery and charger, omitting the tray, grip and case of the SL671 kit. It offers three output levels and a published 90-degree underwater flood beam.
Consider before buying
Its quoted 120-degree beam is the in-air figure. SeaLife specifies 60 minutes at full power and 365 g with the battery; those are manufacturer figures. The head needs a suitable mount, and its flood beam is different from a narrow search beam.
Our take
Choose 2500F when adding continuous illumination to an existing camera rig. Joanna Lentini’s 2017 DivePhotoGuide test liked the 2500’s even illumination for wider scenes, but supplied no numeric overall rating. Compare 2300F for a lower-output option or 3000F Color Boost for dial adjustment and warmer lighting.
