Could anyone tell what kind of tools are out there to measure the brightness in lumens of a flashlight?
<font size="2" face="Verdana, Arial">No sweat... You simply need to build your OWN external power supply. For example - new CD BoomBoxes don't have 12V cigarette lighter adapters anymore. I built my own out of piece of sprinkler pipe & a couple of endcaps to make a dummy battery pack. Round head screws & nuts make up the "battery posts" and are soldered onto a cig-socket extension cord... You get the picture.Originally posted by shipinretech:
The only quibble I have is that it doesn't have an external power source option. Due to the endurance of our adapters, we have to stop testing after only 50 hours because the lightmeter 9V battery will die.
