My wife and I booked a trip to Sipadan in December and will stay with Broneo Divers. Included in our package are daily sunset dives at 6pm or so. For people who had been there before and had done these sunset dives, is there enough light in these "sunset" dives, or is it dark enough that we need a primary light? My wife and I had never done night diving before so all we have are small LED backup lights. If we may need strong lights I want to buy them here before we go. Thanks!
