I would recommend a TigerLight or a SureFire M6. They both have the exact beam that you describe "spot/flood"--i.e. two sort of opposed characteristics combined into one beam profile, a nice hot spot and some throw, with plenty of flood. I use my lights out in the fields and the woods and the stock TigerLight and the M6 HOLA are simply awesome. The TL can also be modded to be much brighter but with reduced runtime, and the M6 can be turned into a rechargeable (soon, anyway). Both things are done by me. So I'm probably a bit biased towards these lights, FYI. Even so, they are both exceptionally good lights, and can be run constant-on without anything melting.
Some lights, such as the Mag Charger running the WA 1160 lamp, will have heat/melting issues if run longer than 5 or 10 minutes at a time. The MC can stand up to this abuse for some considerable while, but eventually the damage is enough to cause problems.
I will be posting a thread on the MC vs. TL vs. M6 soon, if you can wait a week or two, and it will have a detailed comparison with pictures and lots of other good info.
SL 20X or 35X are also possibilities, but I've never used them and so have no first hand experience. Also, you could go for something even brighter and larger, such as an X990.
And keep in mind that while the MC has more runtime, it is also a lot heavier. You will need to decide how much runtime you need and how much weight you are willing to lug around. There is no single "best" light.
I would definitely choose the M6 over the M4, because they are not that different in price, or in carryability, and the M6 will hold its' brightness better over its' runtime. Although, I have heard that some people bore out the M4 to accept two 18650 Li-ion cells and run the M6 MN21 HOLA, but I have no experience with this, and how well it works or how safe it is.
Good luck!
