You're probably better off getting separate items. Only light that does all-in-one is the B&M Luxos, but it is known to have some issues with waterproofing. If you're serious about either then get a good light (can personally recommend the B&M IQ-X as a good light, others like the supernova and edelux) and separate charger. @acharnley is the man behind the D1 which looks very good (it's what I would buy right now), the sinewave revolution also has its fans here.
