This is a preview of the LumaPower Formula 1 LED flashlight.
It uses a 1 Watt R-bin Luxeon LED and a single AA cell
to produce a good amount of light from a pocket-sized
package. The design is very stylish with a 3-D effect
body and polished anodized aluminum.
Body: The body is made up of two tubes - the
inner is the solid water resistant tube, while the outer
tube has cutouts to give the light a 3-D effect. The
tailcap has an interesting design which allows the light
to stand on end with a lanyard attached. Just below
the head you can see a greenish gasket which glows in
the dark after exposure to light so that you can find
the torch more easily.
Bezel/Head: The head of the light contains the
glass lens, 1W Luxeon LED, aluminum reflector, and driver
circuit module.
Output: The white light produced by the LED
is has no noticeable hue in the sample received. Output
is good, producing a smooth, wide spot of light. A dim
spillbeam surrounds the main spot, giving good area
coverage.
Beam at one meter at target center and at target edge
to show spillbeam.
Runtime Plot: Not that great with an alkaline
cell, but rechargeable and lithium cells do well in
this light per the runtime plots shown on their website.
Runtime
completed with "Titanium"
brand batteries. More information on runtime plots is
available HERE.
Switch: Twist the head for on-off. Only one
level of output is available. The O-ring seal does not
provide very much resistance to the twisting action,
to the point where the head could twist very easily
by accident. This is being addressed for the final production
version.
Seals / Water Resistance: O-ring seals protect
the light. It should be dunkable.
If it gets wet inside, just disassemble as much a possible
without tools and let it dry before using again.
Ergonomics: It's a little larger in diameter
than many other 1AA led lights on the market because
of the 3-D body design. However, it is very lightweight.
The textured portion just below the head is actually
part of the head and therefore gives good grip for twisting
the head to turn the light on and off.
Size compared to a common 2AA aluminum light
Batteries: One AA cell powers the light. Alkaline,
lithium and NiMH are acceptable. This preview model
has a problem with Rayovac cells being a little too
short. Adjustments are in progress by the maker. Inside
the light you will not see springs and other such contacts.
The maker decided to go with direct contact posts to
allow for better contact.
To change out the batteries: unscrew the tailcap, drop
out the old cells, place in new cells observing proper
polarity. Reattach the tailcap and you're ready to go.
Accessories: A belt sheath (older version shown
- newer version will be distributed with final), wrist
lanyard, Spare O-rings and spare glow O-ring is included.
Conclusions: Conclusions:
This is a preview review of the light, and as such,
I'm skipping the usual likes and dislikes portion of
the review page. Fixes to be implemented include a larger
O-ring to increase turning resistance of the head and
a longer contact post inside for more battery versatility.
