Flashlight Enthusiast
First off, thanks Bill for letting me participate in this ground breaking project.
JS for the perfect ring potted bulb & beautiful battery pack job that you did.
And Wilkey, for the initial development of Aurora, which brought us to this point.
When I first contact Bill following Shane's (Hallis) pointer. I had no idea what to expect of the project. I knew I signup for something great when I saw JimH and CroMagnet signup but didn't have any idea what it is, how many lumens it put out ... Well after many conversation & PM with Bill, he finally agreed to send me one of the prototype for Alpha evaluation.
A week later after continual surveillance of my mailbox stills nothing. Bill apparently was playing triple duty being a father, mother & some new "real" work responsibilities. I contact Bill and within a few days got a Flat Rate USPS Priority mail piece. I couldn't wait to turn the light on, but … My wife isn't a flashaholic yet so this was the perfect opportunity to convert her. So I waited till nightfall. When we got ready for bed I took out the package, removed the safety tape and flipped the switch.
Doh! It didn't turn on. I thought I blew the bulb, got all disappointed and went to sleep.
The next day I called Bill and told him of the issue. Bill, the safety advocate, disconnected the bulb from the sock so that there is NO chance for accidental ON. Comes that night, when we got ready for bed I hooked up the bulb and flip the switch with two of my CFL bed light (120W halogen equivalent) on. The USL just flooded the room with the beautiful warm light.
I just couldn't help but smile, while my wife said "Oh my god! That is BRIGHT! Is that yours honey" I replied "will be", turned off all the lights and went to bed with a big grin.
Every time I turned on the light I was afraid of Bill caution about the newspaper vaporization incident. I finally got enough courage and time to put everything together for a full temperature test, well at least 6 minutes worth. Surprisingly, the light is very safe when left ON continuously for 5.5 minutes. After 5.5 minutes I turned it off with the temperature reading of 108F/90F. The hottest part of the light is in the middle of the reflector head. It's roughly 5F higher than probe #1 reading at all time.
=== Test Equipment ===
- Oven Mitte
- Bel Merit DX460L multimeter
- Fluke 21 multimeter
- Fluke 80TK Temperature Probe
- Fluke 80T-150U Universal Temperature Probe
- Kapton tape
- and ofcourse a pewter USL prototype.
=== Test Conditions ===
- 68F ambient air temperature.
- USL placed standing on it's tail.
- probe #1 located at 1/4" bellow the reflector head
- probe #2 located at 3.0" from the tail where the palm normally grip the light.
