I was wandering around Fry's Electronics recently and came across their
lengthy stock of flashlights. After trying a few, I decided one in
particular was worth a purchase. It was the Inova X1 and the designation
near the UPC code is X1MT-WT, which describes the white one I bought. I
imagine the WT might change to BK for a black one. But what's so
exceptional? It's just a perfectly simple cylinder with an LED and reflector
on one end and a rubber push pad on the other, with both ends the same
diameter. Press the pad or twist the cap tight to turn it on. Inside is a
single AA alkaline cell. The package specifies it delivers 25 lumens and it
cost me $18.99 plus tax..
Now we all know a white LED requires about 3.5 volts to light up, so this
flashlight must contain a highly sophisticated electronic circuit that
turns the 1.5 volts of a single alkaline cell into 3.5 volts and enough
current to light it quite satisfyingly bright. In fact the Energizer AA cell
in mine has been working for about 3 weeks, now, through many short searches
and a few long ones that really drain the energy from most flashlights. The
cell voltage is down to 1.26 volts, a level at which most portable
electronics just stop working, but not this one. The brightness is only 21%
down from when the battery was new.
To sum up - - this is a flashlight that works on cheap feed, lurks almost
undetectably in a purse or pocket, stays bright long enough to be
dependable, and drains the last drop of energy from whatever you feed it.
What more could you ask?
