not to add more problems, but if you get a 6P you will probably end up wanting it bored out later for 18650 batteries for the larger capacity, you might save some postage, time, money if you buy one that is already bored out...drop-ins...there is nowhere to start, brightness top pics seem to be MCE, triple XRE, the P7, SST-50, and SST-90. But the Malkoff M60 as suggested earlier is a good baseline choice for brightness... and wildly bright to non-flashaholics. The more exotic LEDs like the SST-90 will give you unbelievable amounts of light at a cost to your wallet, battery life, and heat, but anything rated at 200 lumens should suit your needs (but not your wants!) my .02
