Two 9V batteries in parallel still are at 9V, unless so much current is being drawn from them that they can't keep up. In that case they will wear down very quickly. That two 9V batteries in parallel made more light than one tells you that you're in exactly that situatuion. A 35 W bulb would be drawing around 6A from a 6V battery. Little 9V batteries aren't designed to put out nearly that much current.
So my advice would be to cut your losses and ditch the p.o.s. flashlight, recycling the lead-acid battery or saving it for some other use. You can get a nice new LED flashlight that's much more efficient and convenient. You can get these with rechargeable batteries and chargers. It may end up being cheaper than constantly replacing 9V batteries.
