It works well outside, I find there is a alearning curve to any light you use, you have to get used to the distance to hold it and the angle etc...
If you need something NOW why not just go get a halogen for 20 bucks from lowes or home depot. Or even an Incandescent light which I have been using more and more lately. I usually have my 100 watt incandescent a 500 watt halogen a 280 lumen LED flashlight and the brinkman when I am correcting a car. Each light has there own purpose and can pick up certain defects that the others can not.
Just remember when you are using a hand held light source IE not the sun just try to make it as dark as possable where you are shining the light. Either have the car indoors and kill the rest of the lights or roll the car into the shade to check your work.
I polish the car blind and then go over the entire thing before my last step in the polishing process just to make sure all removable defects are gone.
One more thing to keep in your mind is always inspect it in the sun since this is where your car is going to be seen. Usually people do not walk around carrying halogens and brinkmans in there pocket to inspect paint. If it looks good under the sun than call it quits.
