You know, I was in a Dollar General today, and
didn't buy one. I'd been giving it some thought.
The Spirit of the Lord says it's personal choice
if I buy one. Neither encouraged, nor prohibited.
I'm thinking maybe tomorrow. I've got some repairs
needed on the work van, and that means more money
to spend. So, I'm not really eager to spend money
on a research item. Yes, it's only three bucks.
Curiosity got the better of me and when I was at Dollar General
yesterday getting some cheap glucosamine for my knees... I took the
giant leap and got the flashlight. I'm still trying to figure out why a
big double D size flashlight with only one D cell? Maybe because it's
an election year and anything can happen.
Of course I took it apart and there is what looks like a simple
transistor/resister circuit. The voltage at the bulb was about 1 volt
with the light in the circuit. The battery measured... well it's a D
cell so it's 1.5 volt. I suppose the transistor is actually some kind
of voltage regulating thing. The thing will probably be "repurposed"
for a bike light...maybe... or it will fall off the shelf and roll under
the bed.. to be discovered someday and taken to that "what the hell is
this thing and what's it worth" show on PBS.
Further independent study for those wanting extra credit...
I had a weak moment, today. Went and bought one. The
one battery worked, the light shines a very blue,
poorly focussed spot on the ceiling. It's about
twilight, so it's a pretty fair test of light output.
I plan to do some testing after dark. Also check amp
draw, battery life, and a few things like that.
So far, with the initial moment or two of testing, it
appears to be a reasonable value.
Package says it's an Open Trails brand one LED
light with 1 D battery. Made in China (why would
that surprise anyone?) Distributed by
Dolgencorp. Product Code EP-251.
The bulb is more like a Cree emitter than LED.
Square base, not the round top bulb like the HF
The light is slightly brighter than a Harbor
Freight free 9 LED light. The light is a
little whiter than the HF light. It sure would
be nice if the beam was whiter. But, it is
I tried the light in totally dark rooms. Sure is
better than being in the dark. I also tried the
light down the hall of my trailer. It is plenty
bright enough to see if there was a burglar.
The closed end of the light has a swing out loop,
for hanging. Sure enough, the light hangs nicely
by the loop. Hanging on a nail, it would be good
resource for power cuts.
One of these days, I'll check the amp draw, and
do a life test on the provided battery. And what
ever other tests. Might take it outdoors, see
how far the beam reaches.
Yes, that is correct. The battery in question
is a carbon zinc D cell, worth about 35 cents.
It will self discharge in about a year, and
then I can put it in the trash without getting
any use out of it.
This is unusual. With the usage time you got, I assume it's an LED torch. D cells haven't been around for ages. LED torches tend to take AA or the Lithium Ion equivalent. Is this a home made torch or a conversion?
All I ask is a chance to prove that money can't make me happy.
Please read some of my other posts, under
similar subject lines. I've explained all
this. And I thought clearly so.
D cells have been around for at least 60 years.
I have a flashlight "torch" that belonged to my
great grand father, takes two D cells.

One bulb. Looks more like a Cree emitter, rather
than a LED. Yes, Carbon zinc cells are very easy
to find in stores in the USA. Very low energy
capacity. Low amp delivery. And they lose power
rapidly. And leak easily. Brown corrosion, around
the flat negative end.
When I was a kid (before alkalines were invented),
my Dad bought a charger that was supposed to recharge
carbon zinc cells. The second charge didn't last very
I'm prefectly willing to use up such a cell,
So why does anyone buy them? You'd only be fooled once.
10 years ago I was looking at chargers for zinc carbon/chloride and alkaline. They only charged them 10 times and the charged cycles were much lower capacity than the original.
I think all the charger does is do it slowly.
