Green Force manufactures gobs of dive lights. One of their new lights, the Flexi Fun Star got its silly-sounding (and slightly porn-y) name from the components that compose it: the "Flexi Fun" battery pack and the "Star" lighthead.
The battery pack takes 8 AA alkaline batteries (or 8 rechargeable AA NiCd/NiMh batteries), and the Star lighthead contains a 3 Watt LED that provides a burntime of 16 hours (8 hours at 100%, plus 8 hours at 50%). However, because the Flexi Fun features a universal connection, you can easily switch out your light head and replace it with a Green Force HID 50 Pro or Tristar instead.
Although Green Force boasts that this light is great for beginners, a Flexi Fun Star will run in the neighborhood of $400, which is arguably not a beginner price.
