Lumens, Watts, and Candlepower… oh my!
Okay, I know everyone has heard of these terms, however most times these terms are confused in normal everyday conversation. I am going to attempt to explain them to you, our readers.
What is a lumen?
A lumen is a unit of measurement of light. More importantly, a lumen is a way of measuring how much light gets to what you want to light. For example, if you shine a flashlight at a wall 20 feet away, how much light actually hits the wall? The more lumens the more light the wall will receive…
What is candlepower?
Candlepower is the measurement of light taken from the source or the amount of light the bulb produces.
Finally, what is a watt?
A watt, in simple terms, is the amount of energy used by the bulb.
These terms are important, especially when you buy a flashlight because it can actually save your life. Using the definition above wouldn’t you rather have a 270 lumen flashlight as opposed to a 200 lumen flashlight? I don’t know about you, but those extra 70 lumens can help you identify a potential life threatening situation faster.
What do you think?
So what is the REAL ship date going to be for this light???? I place an order in October 2008 and was given an invoice stating that the light would ship in February 2009, then we were told April 2009. Now I saw that it was going to be mid-June 2009. So when are we going to get these lights??? Can anyone give us a definate answer?? I find it hard to believe that there aren’t some lights that are ready to go if the original ship date was Feb 09. I have a light that is currently working less by the day. If I can’t get this light sometime soon I may have to cancel and purchase something so I am not working in the dark. Please let us know when we will get these FOR SURE.
Thanks,
William Hanney
