I stand in aw of the seemingly magical power that Candle Power Forum possesses to destroy flashlights from many hundreds or even thousands of miles away. It was only a few weeks ago that I had a perfectly good, nearly new looking 3-D cell MagLite. Now, after spending some time reading through the forums and purchasing a couple Fenix lights, my MagLite has become nearly useless.
Two things for you:
First, :welcome: It's good to see new CPF'ers learn about our little hobby.
Second, ABANDON ALL HOPE, YE WHO ENTER HERE. You will never be the same again. You will develop a preference for quality, craftsmanship, performance, and fair play. You will spend more money than you should on more lights than you need to often use them in places that have readily available light already. And, as you've already found out, all the flashlights that you thought were useful and adequate become dim and unsatisfying. The only cure is CPFMarketplace, CPF Custom and Modified areas, and lots of money.
Have fun, enjoy yourself, and remember that there is often a fine line between what you need and what you want.
