Step 1
Make a list of all potential uses for your new flashlight. Perhaps it will be used only in power outages. A lot of people use flashlights for doing work around the house. Do you tinker around in cramped quarters? Will you take it camping or outdoors? All of these factors can help you determine what kind of flashlight to buy. Keep them in mind as you make decisions regarding bulb type, power source and body style.

Step 2
Choose what style of bulb fits your needs best. The bulb is the heart of the flashlight and determines brightness and range. Incandescent bulbs are the most common. These bulbs are cheap and provide adequate light. However, they can break easily if jostled or dropped. Because of that, many people are turning to LED flashlights. LEDs are praised most for their energy-saving abilities. Again, think about use. If you need a flashlight sporadically, go with an incandescent. If you're more concerned with long-lasting light, choose an LED. You'll also want to test out the flashlight's range.

Step 3
Decide what kind of batteries you want your flashlight to use. Most standard flashlights will use two to three C or D alkaline batteries, which are relatively cheap and definitely easy to find. Other choices include lithium batteries or rechargeable batteries. There are even solar-powered flashlights. The newest trend is "forever flashlights," which don't use batteries or lightbulbs. A tiny generator, activated by shaking the flashlight, powers it. Because nothing ever needs to be replaced, these flashlights are a good choice for someone who uses flashlights often.

Step 4
Determine the style and size of flashlight you want. Flashlights can be made out of plastics or metals, which affects weight. Think of use. If you'll be toting your flashlight outside or up ladders, you'll want something compact and lightweight. For big jobs where a lot of light is needed, try a lantern style flashlight. Some people even prefer headlamp-style flashlights. Pen lights or mini flashlights are great for some projects and can be hooked to your keychain so you can always find them.
