The first thing that caught my eye when I pulled this
one out of the box was the head of the device. Is this
a new shower head? Perhaps it's a hamburger patty press?
Nope, it's a photon hose! 100 LEDs, powered by 4 AA
cells in a special carrier, producing about the same
amount of light as a well-driven Luxeon III or a Surefire
E2e.
Body: The body is anodized aluminum and consists
of a very large head, a ringed step-down area in front
of the side-mounted switch, a ring of knurling, some
decorative rings, a rubber body tube cover, more decorative
rings and finally a grooved ring on the tailcap for
grip. Overall construction was found to be.... ummm....
adequate? The machining was fairly rough, and the threading
on the tailcap was very rough. The tailcap tends to
bind the first few times you use it until you manage
to shave off the burrs through use. The tailcap is flat,
and you can stand it on end for "candle mode"
use if you would like to light an area by bouncing the
light off of the ceiling.
Bezel/Head: The head is the interesting part.
100, yes I counted them, 100 LEDs recessed in a faceplate.
Now it is important to note that it says on the side
of the box, "For normal working, please don't open
the head of flashlight." Well folks, they mean
it, as I found out. Being the inquisitive type, I chose
to ignore the instructions. After hearing a gentle "snap"
when the head was almost completely unscrewed, I realized
I may have made a mistake. Inside the head is a single
huge resistor sticking straight off of the board that
holds the LEDs. This is wired to the switch. A second
wire comes from the edge of the plate and goes to the
contacts as well. Unscrewing the head twists the wire
attached to the end of the resistor and snaps it off.
Soldering the wire back onto the resistor doesn't do
any good since you have to twist the head about 15 times
to screw it all the way back on. After making a really
good solder joint onto the resistor, the resistor itself
decided to snap off of the board. So we try again....
This time I used about 3 inches of wire to connect the
resistor to the board so there was lots of slack to
twist up inside the head. Bingo - we were back in business.
It looks like the light is assembled so that the head
is screwed in place minus the LED board and faceplace.
The switch, LED board, and faceplate are then placed
directly into the head and pressed into place so there
is no need to twist the wires inside. End result: Don't
unscrew the head unless you are ready to do some substantial
soldering to get it to work again.
Output: The white light produced by the LED
is a high color temperature and produces good color
rendition weighted toward the blue end of the spectrum.
A very slight bluish tint is detectable when compared
against a near sunlight-white source, but this tinting
is not noticeable during normal use. The spot is a very
even round spot of light with a slight spillbeam and
a distinct ring at the very periphery of the output
area. Overall it provides a very well defined spot of
very even light. Note that all of the LEDs are not exactly
the same in output. Some are brighter, some dimmer.
The fact that there are 100 of them allows the beam
to be very smooth with no noticeable brighter or darker
areas.
Beam at one meter at target center and at target edge
to show spillbeam.
Runtime Plot: The runtime wasn't all that bad.
Pretty typical of an alkaline cell powered light. You'll
get about 1 hour and 20 minutes of continuous output
before hitting 50%, and a distinct drop in output around
the 1:45 mark.
Runtime
completed with Rayovac brand batteries. More information
on runtime plots is available HERE.
Switch: The switch is a rubber covered "reverse"
clickie. Press until it clicks for on, then press gently
to blink the light. Press fully until it clicks for
off. The button is fairly well protected by the protrusions
in front and behind the switch, so accidental activation
is fairly unlikely.
Seals / Water Resistance: I don't see any real
evidence of serious water resistance incorporated into
this light. Keep it dry.
If it gets wet inside, just disassemble as much a possible
without tools and let it dry before using again.
Ergonomics: It's fairly large, but not excessively
heavy. This is a "carry around" type light,
not a "put in the pocket" type of light. The
large head diameter (7.5 cm, 3 in.) makes it a bit awkward.
Size compared to a common 2AA aluminum light
Batteries: Four AA alkaline cells power the
light. They must be placed into a special carrier that
is keyed so that it can only go into the light one way.
The carrier is not all that well made, but it works.
Put two cells in pointing one direction on one side
of the carrier, but the other two in pointing the other
direction. Negative goes against the springs in the
carrier. Drop it in and if it doesn't go all the way
in, twist it around until it drops in place.
To change out the batteries: unscrew the tailcap, drop
out the carrier, remove the old cells, place in new
cells observing proper polarity and drop in the carrier.
Reattach the tailcap and you're ready to go.
Accessories: None
What I Liked: Good output, decent
runtime, nice "wow" factor with 100 LEDs.
What I Didn't Like: Construction
is coarse in some areas, Can't unscrew the head without
causing damage, Not water resistant.
Picky Little Things: Uses a battery
carrier (I just don't like these - one more thing to
break)
Conclusions: Despite the manufacturer's
name, it isn't a total piece of Shitiao, but it's not
a very high quality light either. Good for around-the-house
tasks but I wouldn't depend on it as my only light when
safety was an issue. I expect that this may be the most
extreme use of an array of 5mm LEDs we'll ever see,
especially considering that there are now arrays of
Luxeon LEDs appearing on the market, and a single Luxeon
III can produce as much light overall as this 100 5mm
LED flashlight.
