Here is an idea that occured to me last night after reading Peter G's posting about Lithiuim squeeze lights. I propose to quantify Light Density using the following equasion which is based on measurable values:
LD = (B * T)/V
Where:
1. "B" is a standardized measure of brightness or light output (measured at one minute after turn-on with fresh batteries).
2. "T" is the time it takes for the flashlight to reach 80% (or some other value) of the value of "B".
3. "V" is the volume of the flashlight in cc's. The volume can be measured by submerging the flashlight in water and measuring the amount of water displaced by the flashlight (1ml = 1cc).
By dividing the Brightness*Time value by the Volume of the flashlight, large flashlights are penalized for their size.
Comments?
