Howdy coltchris, and welcome to CPF,
You know, it happens all the time. A new member finds CPF while looking for a particular light, only to end up realizing that a completely different light might be more useful.
I'd recommend that you hold off purchasing anything for a week or two. Spend some time becoming acquainted with the various types of lights that are available. Sometimes it's the small differences between lights that can make a huge difference in how easy they are to use.
For instance, the UI (user interface) is something I always think about before a purchase. How many light levels does it have? How are they spaced? After the initial WOW factor of a really bright light wears off, most CPF members begin to realize how really useful the lower light levels can be, and many of us won't even consider a light without a "moonlight" mode.
Does it have a "memory" mode (comes on in the last level used) or does it come on in the same level each time? There are good and bad points to each, but it's important to realize you have a choice. Some folks want their light to come on in low every time, some want it to come on in high, and some prefer to either have a memory mode or have a light that gives a choice of either high OR low from off (Zebralight).
Tint and CRI, the color and quality of the light, have become hot topics hear on CPF. Many manufacturers now offer "neutral" or "warm" tinted versions in addition to the "cool white" LEDs that typically come standard in most LED lights. Spend some time learning about the differences.
Many of us here on CPF prefer to use rechargeable batteries, but there are many types to pick from, so I'd also recommend that you learn about the various types and why one might be better than another for a particular application.
The idea is to spend your money wisely. I think many CPF member carry at least 2 lights. A good keyring light and another EDC light. Think about how you will use your light and let that guide your research.
