Rechargeable Flashlight

* This light was provided in exchange for an unbiased review courtesy of

WWhen approached me about reviewing their new brand of
lights I was intrigued.  The PalmStar was a good looking light.  They
are relative new comers to selling lights and when they decided to create their
own brand of unique lights they went with quality first.  Their new models
are made by Niwalker lights and it is readily seen once you have the PalmStar in
hand.  Machining and anodizing are great.  The design, with a couple
of exceptions, is well thought out and executed.  The UI is fairly unique
which is a hard thing to accomplish these days.  Output is, at least on my
sample, less than claimed but still better than most. 

I would say that the Palmstar’s direct competition is the MecArmy PT18. 
Both are USB rechargeable, quad XP-G2 lights, with 1000 lumens output. 
While the PT18 sells for around $60 USD, the PalmStar sells for just under $50. 
Unfortunately I don’t have any of the MecArmy lights so the only light I have
that is even close for comparison is my Astrolux S41.  The S41 is out of
the Palmstar’s league in output but the PalmStar holds up quite well
considering.  Let’s take a look at TOP’s ( marketing
copy for the PalmStar before we get into the performance of it with my testing.

User Interface
Turn the light ON/OFF by the side switch. Once you release the switch, the light
comes on constant mode.
When the light is on, single click the switch within one second to cycle through
all the modes, mode memory remembers the last mode used.
When in stand by(light off), press-hold the switch for momentary max output.

When in stand by, double click the switch for instant strobe.
Double click from on to access the hidden modes.
Double click for SOS. another double click-for beacon mode Single click the
switch gets you back to off. Note there is no mode memory for hidden modes
Lock-out mode is accessed by twisting the light body.
Mode 5 (max output) steps down to mode 4 when thermal protection kick in to
prevent over heating.

Unscrew the light body then insert the Micro USB cable into the charging hole
and connected to the power supply equipment, the indicator turns red while
charging. Charging time is about 4.5 hours, the indicator will turn green when
charging is complete.


Output, at least on my sample, is a bit less than advertised unless the
advertised output is measured at the emitter like Armytek does with their lights
instead of out the front (OTF).

The driver is current controlled in all modes and there is no visible PWM at
any time.  Tint from the cold white XP-G2 emitters is what one would expect
and some will love it, others will hate it.  In person it seems a pretty
pure white in the higher output levels but in lower modes a purplish tint seems
to effect the beam, at least when white-wall hunting.  I think this is due
in part to both the purple AR coating and the current control.

AAs you can see, output is less than claimed by roughly 25%.  Throw is a
lot less than claimed.  Given the tight little hot spot on the PalmStar’s
beam I was surprised by the lesser than claimed throw.  I measured from 9
meters (my standard testing distance) and from 2 meters but from 2m the
measurement was even less.  This proves that the farther away from the
light source lux is measured, the more accurate your results will be due to
reflector focus and beam collimation.

Ideally, as I said above in the introduction, a MecArmy PT18 would be the
ideal comparison flashlight.  Size, output, recharge ability and build
quality are super close.  Unfortunately I don’t have a PT16/18 to compare
with the PalmStar so my Astrolux S41 (Manker E14) with it’s quad Nichia 219B
LEDs will have to do.  It’s not a fair comparison as the driver in the S41
is a FET based driver that provides as much current as the LEDs can take. 
Surprisingly the PalmStar holds it’s own, especially indoors with a ceiling

^  This photo shows the beam artifacts from the overlapping reflector
cups.  Outdoors the artifacts aren’t noticeable.

^  Here is the S41 from the same distance of about 1m.

^  The S41 appears brighter by itself until you shine them side-by-side
from about 2m distance.  The focused spot of the PalmStar overwhelms the
floody beam of the S41.  The tint difference is obvious due to the high-CRI
output of the Nichia LEDs in the S41.  The PalmStar uses CW (cold white)
Cree XP-G2 emitters but thanks to ease of removing the MCPCB, the LEDs can be
swapped if you are comfortable reflowing emitters.

^  The animated gif above shows just how close in output the PalmStar is
to the more powerful S41.  Both pics were taken a minute apart with the
same camera settings in an otherwise dark dining room.  Brightness appears
about identical except for the slight difference in tint.

^  The garage door in the pic is about 33m away.  This gif above
demonstrates each of the 5 output levels of the PalmStar.

^ Above is a comparison between the TOP PalmStar and the Astrolux S41. 
Due to the focused beam of the PalmStar most of the light is on the door and
very little on the building behind my garage and across the street.  In
person there is a bit more spill than is visible in the photo.  The broad
flood of the S41 is apparent.


The single button UI is unique among any flashlights I’ve used before. 
The PalmStar has mode memory, single-click On or Off, momentary access to Turbo,
and 3 hidden flashy modes.  The UI is simple to use and easy to figure out
but more than most relies on timing.  Changing modes must be done within
the first 2 seconds of turning on the PalmStar and after each subsequent change
of modes.  If 2 seconds go by without clicking the button any click after
that will turn Off the light.  Instead of retyping the UI instructions I’ll
just repaste the directions given by TOP (

MMy comments regarding step-down from Turbo (mode 5)…  When the light
is turned on when cool to Turbo from anywhere but momentary it consistently step
downed to High (mode 4) in exactly 30 seconds.  After that, Turbo can be
re-enabled by a quick click to turn off then a click to turn back on in high and
a second click to reenter Turbo (mode 5).  It all takes no time at all to
hit the quick clicks needed.  If the light is already hot, or still hot
from being in Turbo, this is when the thermal control kicks in and limits the
amount of time the PalmStar will stay in Turbo.  Could be a couple of
seconds, could be much longer but after that once it hits it’s preset thermal
limit it will cut back down to High mode (mode 5).

Once the light has been on in any given mode for more than 1 second, to
change the mode again you need just turn it off with a quick click then turn it
back on in the mode you were in before you can change to another output level. 
Mode changes must be done quickly before the 1 second press timer kicks in. 
It’s really not as bad as it may sound but it still kind of sucks and could be
MUCH better.  I’d like to see a long press to turn it off and mode changes
be done at any time with a single click.  It’s good to be different
sometimes but not at the expense of ease of use.

^  Part of the user interface is the ergonomics and the PalmStar really
succeeds here.  The electronic switch is firm with a good tactile feel when
clicked and falls perfectly under the thumb when held.  In spite of the
small size of the button, it’s actually easy to locate by feel.  The
compact size feels great in the hand and that diamond plate style
knurling…wow!  This is the grippiest flashlight I’ve ever held. 

^  The PalmStar is easy to charge thanks to it’s hidden USB port. 
Unlike most rechargeable torches, the PalmStar has it’s Micro-USB port in the
threads of the light where the O-ring seals and protects perfectly against water
or dust ingress.  No flimsy rubber port covers like the other lights use
that come loose, tear off, or leak easily.  The red and green LEDs behind
the white plastic cover show charging status at a glance.  Charging
terminates once a voltage of 4.16V is reached.




^  The PalmStar arrived in a plain, well designed, corrugated box. 
The light is securely fixed in the box with a compartment for accessories along
one long side.

^  Accompanying the PalmStar inside the accessory compartment is a well
made holster, quality lanyard with lobster clip, spare O-ring, and simple, but
detailed user pamphlet.

^  Here is a scan of the user pamphlet with all specs on the PalmStar,
UI instructions, and charging details.  Pretty much all you need to know
about this well made little light.

^  The lanyard is very well made and fully adjustable.

^  The included holster fits the PalmStar perfectly.  Construction
is sturdy but simple.

Now on to the good stuff…

^  The PalmStar is a great looking little light with a very clean
design.  The simple, small, single switch is located perfectly on the head
of the light.  The metal button is unobtrusive but to find by feel due to
it’s location on the only flat machined on the head.  No fins grace the
head but it still manages heat well.  The PalmStar gets warm quickly on
it’s highest mode but keeps from getting too hot thanks to the combination of
timed and thermal step down in output.

^  All branding on the light is clean, solid, and crisp.  Anodizing
is fantastic throughout.

^  Unlike most compact quads these days, the PalmStar uses a machined
aluminum reflector instead of the usual TIR optics.  Due to the overlapping
reflector cups there is the accompanying "lotus blossom" effect (my term) in the
whitewall beam profile.  The benefit is a tight hotspot in the beam.

^  The battery tube is machined with a diamond plate type pattern. 
It is ridiculously grippy!  I was amazed when I first held it in my hand./p>

^^  The tail cap has standard type knurling for grip when removing it to
install/remove the cell.  Two large lanyard cutouts in the tail bezel allow
easy direct attachment of clips, installation of split-rings, or direct
installation of lanyard cord/Paracord.  Chamfered openings prevent early
wear and cutting through of lanyard cordage.

^  Wide, flat base provides solid tail standing for candle mode. 
The Palmstar’s serial number is engraved on the flat of the tail cap.

^  Charging circuit is contained in the battery tube of the light while
driver and UI switch are located in the head of the light.  To charge the
PalmStar simply remove the head and plug in the Micro-USB cable.  The cell
is only accessible from the tail of the battery tube.

^  The head of the PalmStar is crazy sturdy.  Driver PCB seems
thick and the anode (+) contact for the cell is a solid brass button that makes
solid contact with the matching button on the battery tube.

^  All threads throughout the light are square cut and thick. 
Threads on the battery tube are unanodized and look a bit rough but rotate very
smoothly.  The anode contact button on the front of the battery tube is
spring loaded.  TOP claims that the light can be mechanically locked out by
unscrewing the head but doing so takes it past the O-ring and the head could
easily unthread itself the rest of the way and come off.  I’m not sure why
they didn’t anodized the threads for perfect lockout.  Hopefully this will
be corrected in an updated version./p>

^  The tail cap threads and threading at the back of the battery tube
are also unanodized.  A raised button machined into the tail of the light
provides contact for battery cathode (-).

^  A look inside the battery tube reveals a spring for anode contact.

^^  One complaint I have with the PalmStar (aside from the lack of
anodized threads) is the short length of the battery tube.  Machining on
the PalmStar is phenomenal and without a cell installed all the main body joints
fit seamlessly and flawlessly.  The person in charge of the design needs a
spanking for designing the tube for cells no longer than 65mm so that even an
unprotected flat-topped Samsung 25R leaves the tail cap short 1mm from closing
properly.  I recommended to TOP (theoutdoorsplus) that they redesign with
at least 2-3mm more length in the battery tube so that the tail cap can seat
perfectly flush as it should have been designed to do.  Even a button
topped 30Q technically fits but with an over 2mm gap while still having the
O-ring sealing the joint properly.  NEVER, NEVER, NEVER design a tube for
exact fit with a specific cell unless you are going to include that cell with
the light.  If you put a spring as a cell contact then clearly you were
planning on cells of varying length to be used.  Make the tube long enough
to at least accommodate cells 68mm long.  This is especially true when a
light is so well machined that the seems would otherwise have been invisible to
the naked eye.

^  Having looked at the outside of the light, let’s have a look
inside…at least part of the way.  Removing the unglued bezel from the
head of the PalmStar gives us easy access to the innards.  Inside  and
easily accessible are the lens, lens O-ring, reflector, single MCPCB with
4*XP-G2 emitters, and four individual LED centering rings.

^  Threads on the head and bezel are the same as the rest of the light
except these are properly anodized.  Like the other threads, they come
pre-greased and the O-rings fit super tight and snug./p>

^  The reflector is machined from aluminum billet and fits perfectly.

^  The MCPCB is secured to the emitter shelf with two screws. 
Thermal paste is used to seal the contact between MCPCB and head.

AAnother suggestion I made to TOP was to change the centering rings used. 
Not only are they very thick, but the lips used to center themselves in the
reflector are way too tall and thick.  They actually interfere with the
outer edges of the beam and block a little of the light.  Soldering is well
done.  Wires to the emitters seem a little too thin as well.  Granted,
with only 1000 lumens of output, the thickness is probably acceptable for the
current being used to drive the LEDs.  This light has some serious modding
potential and with a proper driver could push the quad XP-G2 LEDs to 2000 lumens
easily.  Still, it is overall very well thought out and the build quality
and anodizing are fantastic.


^^  Aside from head diameter, the PalmStar isn’t much bigger than the
Olight S20 in length.  On the edge of pocketable, at least in pants
pockets, it’s compact size disappears in cargo pockets or in a jacket pocket. 
When worn on the included holster, it does make for compact EDC belt light.



TThe PalmStar certainly isn’t a perfect light.  I haven’t found any yet
that are but it does a lot of things right and only needs some slight changes to
be great.  What would I change and what do I really like?  Here is a
list to wrap things up.

Changes: /p>

  • Battery tube needs to be 2-3mm longer so the tail cap can be fully
    screwed down for perfect, flush fit of tail cap.  Any cell longer than
    65mm leaves a corresponding gap between battery tube and tail cap.
  • All threads need to be anodized, at least the threads where the battery
    tube joins the head.  This would allow for mechanical lockout. 
    TOP claims ability to be locked out by "twisting the light body" but in
    reality the head must be unscrewed past the point where the O-ring grips the
    head before the circuit is broken.  At this point just a little more
    "twist and the head falls off, or a little more twist tighter and the
    circuit is closed again before the O-ring slows it down.  Fortunately,
    thanks to the small, recessed switch button and it’s location the chances of
    accidental activation is very unlikely.  Any long term storage without
    use just remove the cell.
  • I don’t care for the 2 second timer in button presses before mode
    changes stop and the power gets turned off.  It would have been much
    better with no other change than removing the 2 second timer and making
    "Off" a long press of the button.  With any EDC light I’d like to see a
    Moon low added into the mix as well.


  • Finish and machining quality are amazing.  You can tell that this
    is made by the same factory that makes Niwalker.  Anodizing is
    fantastic hard ano.
  • Super compact size and nice reflectored head instead of the growing
    trend for TIR optics on multi-LED lights this small.
  • That knurling!
  • Easy USB recharging and waterproof port design.
  • Nice holster
  • Good output levels with lots of room for modding.
  • Very competitive price with comparable flashlights.
  • Great light for flashlight noobs that want to get into Li-Ion lights
    with no muss, fuss, or chargers needed.

It’s not a perfect light but it’s still pretty good.  Lots of great
qualities.  Works well, feels great in the hand, and high quality
construction.  For an entry model from a new manufacturer it’s a pretty
impressive torch and worthy of your consideration.  I can’t wait to see the
updated version or their next EDC model.  TOP’s future looks like it could
be pretty bright.
