You can use a laser pointer for more than just pointing at things. To wit:
Here, an orangish-yellow laser pointer is being used to examine the insides of a soft white incandescent light bulb.
To do this, just hold the bulb with one hand, and shoot the laser into the side of the bulb facing away from you. By doing this, you can immediately tell if the light bulb is burned out or not. This works with soft white or frosted bulbs, and allows you to see the filament inside - and determine whether it is broken or not.
I don't have a busted light bulb here; the one shown above is a new one.
I've been testing light bulbs this way for years; it was my sister that suggested that it be placed on this website.
Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light did? If you have a sample available for this type of real-world, real-time testing, please contact me at ledmuseum@gmail.com.
Please visit this web page for contact information.
Unsolicited flashlights appearing in the mail are welcome, and it will automatically be assumed that you sent it in order to have it tested and evaluated for this site.
Be sure to include contact info or your company website's URL so visitors here will know where to purchase your product.
