That's it. You can add some insulation so that it doesn't overheat. My first one burnt out because I left it on too long with no insulation. Now you can focus the beam and it will light matches, fireworks and make most black paper and rubber melt. Make sure you use appropriate glasses and safety precautions. just by looking at the reflection hurts your eyes and gives you a headache. Remember always be cautious.
