Hi Guys!

I got a Sunwayman F40A from banggood and want to share a few pictures and thoughts…

13 days after “shipped” i got a nice cardboardbox:


the light ist very safe in there!

it comes with a diffusor, a lenyard, 2 O-rings, operating manual in english and chinese (i guess) and warranty card

the lens is AR coated and everything is clean

the F40A is smaller than i imagined!
anodisation and laser engraving are first class

weight: 284g with 4 Eneloops

Batteries are 4S0P

the Batterieholder is made just right - nothing rattles!

the Threads are square and slightly lubed

the XM-L2 is well centered

also the colorLEDs are sitting nice in their “minireflectores”

ookay - most of them…

the colored LEDs have a uneven Beam

5cm distance (yes - 1 of the reds has had a loose contact)

20cm distance

50cm distance

20cm distance

50cm distance

last but not least: 2 Gifs from 1m distance…

UI
the two side-switches are easy to click (maybe a little to easy)
the light has last mode memory
pushing both buttos for 1sec toggles lock-out (light strobes 1sec)

●white:
klick [on/off] > starts in last stored white
[mode] > white goes from turbo-high-medium-low
doubleclick [on/off] activates strobe (from on and off)
doubleclick [mode] activates SOS (only from on)
holding [mode] when off > firefly

●color:
holding [on/off] > starts in last color mode
[mode] > white goes from red - blue - red/blue flashing - red/white/blue flashing
.

conclusion
i was impressed from the very good build quality and the nice touch.
it fits just right in my hand and my pockest do not rip appart when i carry the light.
in the lower modes i can hear some whining - but i dont see PWM!
.
-> I like the light - and even my wife says “that thingie is very cool!”

@M4D M4X You got PM.

best price !

I ended up ordering the even newer F30R. Same diameter but shorter at 91mm and it takes three Cr123A or 16340 batteries. I wanted the more compact length as all other specifications are listed as the same. Illumination Supply has the new light in stock and their BLF discount code is giving 15% off of their normal price on it.

9

did you pay the 74,99?

you can find the code on my blog :wink:

10

$76.41 + shipping as total before discount was under $100. However I will have it on Monday or Tuesday as IS is only about 250 miles away. I saw the GB price for the four AA version before I ordered mine.

11

what would one do with a red/blue/white light flashlight?

12

Red is good for retaining night vision though this light sounds like the red is bright enough so it may actually be a bit on the bright side if used w/o the included diffuser. Amateur astronomers are major users of red flashlights or filters. Blue light is used by hunters and criminal investigators to aid in finding blood traces or following blood trails in poor light or at night.

Some hunters use high power red LED lights for night hunting where legal as many animals are blind to red light.

13

As I know,colored LEDs are useful when hunting and fishing,many company are releasing colored flashlights

14

I just recieved a F40A, its a great light, but i may swap the Blue LEDs to either UV LEDs or warm white.
The red LEDs are great for night map reading or use to help keep night vision, (dimmed with the use of the diffuser) and warm LEDs in place of the blue would be better for use as a night camp light or lantern with the diffuser, or UV LEDs for the night Geocaching that i do, either way it makes this light more versatile for what we use lights for.

nice - I hope there will be a worklog :wink:

16

pardon my sleepiness tonight :stuck_out_tongue: - what is a worklog ? as in mod topic ?

17

yes - as usual in the mod section…

I understand a worklog as kinda step by step pictures which document your work.

18

ok will do once i recieve the LEDs i have on order fro it.

Good afternoon, first of all I appreciate the full review and the assessments that followed. I need to ask a question. Yesterday I reached my Sunwayman F40A and after a while you use it and test me off by itself. When this happens not turn over. I have to unscrew the battery cover and re-tighten (A manual reset mode) and there restarted. I tried to see if it responds to a pattern accidentally touch keys, but no. Not much logic. Today I returned to light and long time stays on, when I start to change modes there is a moment that goes out and must return to unscrew the battery cover and re-tighten (which manual reset) and then returns to work … … :frowning:
Any ideas or suggestions? You have some electronic failure?
Thank you very much!

good luck with that. My F40 failed too, ( as did all three other Sunwayman lights i had. I have had no good luck with Sunwayman lights, they all had problems and sunwwaman refused to help me or fix these under warranty. I recommend avoiding Sunwayman at all costs, their drivers & Quality control are trash and very unreliable.
