limited production :: hand crafted :: high performance :: rechargeable :: premium flashlights

This is my blog about creating a startup LED flashlight business. I'm a designer, fabricator, and strategist and I'm passionate about making ideas real. I believe that products are about people, that they should be built to last, deliver real value, and that we need to do a better job than we have in the recent past.

Most of my career has been contract or freelance work and I've crafted products and strategies for both big international companies and startups. I also used to work in the "industry" fabricating special effects for film and TV, along with the occasional hot rod. Bottom line, I love making things.

I'm starting this blog so you can follow along, from day one, and see what it's like to start a business, or fail in the process. Only time will tell, but I hope you find this interesting enough to stay tuned, comment, link, like, tweet, and (most importantly) participate in turning this idea into something tangible and valuable.

WIN! 90 Minutes run time on High--Tested!

One of the main questions I get is about "run time" and exactly how much you should expect. I'm an applied science type of person and I like to test my assumptions rather than just guessing...and I finally got around to some testing! I tested three lights with fresh batteries and ran them on high. I'm excited to announce you should expect approximately 90 minutes of run time on high. Please keep in mind, the hotter the light gets the less efficient the LED...and the lower the run time.

A well lit beverage!
I added a few ice cubes to keep the light from getting really hot. A 90 minute run on full blast produces a lot of heat. Holding the light in your hand (like submerging it in water) helps draw the heat out of the light and keep it cool. If you ran the light on high for 90 minutes and left it sitting on a table it would most certainly overheat. In general, do not run the light on high for more than 10 minutes if you are not holding it in your hand! 

I conducted 3 trials: lots of ice, 4 cubes, and room temp water. The three lights I tested came in at 115 minutes, 93 minutes, and 85 minutes respectively. The room temp water was noticeably warm at the end of the test. Many factors contribute to run time so your mileage may vary...especially if the ambient temperature is high. The cooler the light, the longer the run time!
