1. Decide the reason why you want to buy a led flashlight

2. Set a budget. Many flashlights are available for under $10 or $20, but some specialized, LED blister package flashlight may cost ten times that.

3. Look for the brightness, measured Fluorescence Flashlight  in lumens.

4. Check the number of bulbs.

5. Choose something with good soldering, connections, and switches.

6. Choose an appropriate size and weight.

7. Choose a battery type that's right for you.

8. Look at the bulbs. With the light bulbs off, you can look at the consistency of the work that went into mounting the bulbs.

9. Choose a housing material. Plastic is lightweight; aluminum is likely to be more durable.

10. Turn the light on and look at the shape of the spot it projects.
