My brother decided to buy some Coleman lights ,
so that gives me the opportunity to give them a quick look over and
possibly some feedback to you guys should you be looking to buy . Now
the most outstanding feature has to be the battery lock out . One has to
twist the head anti clock wise which reveals a red anodized ring ( body
) which shows you that you are in the battery lock out mode . Obviously
this is to stop accidental activation and or any power drain when not in
use ( Storage possibly ) .
Both lights are dual mode ( High - Low ) and
for a lot of people that is probably enough . What I don't really care
for that much is that you need to cycle through both modes to turn the
light on or off ( ok you could cheat and just twist the head to turn the
light on or off ) . Speaking of twisting the head , if you turn
the light on and twist off , and you twist back on ( the light turns
back on ) . So the switch does not apparently reset . ( Mechanical
Anyhow , both lights do push out a lot of light
and make earlier LED attempts look weak in comparison . It is really
good to see mainstream manufacturers ( Flashlight ) finally produce
lights that are powerful and run AA batteries as well being available to
the masses VIA the local supermarket . Both lights come with
batteries and unfortunately lack some sort of comprehensive instructions
I thought the 250 Lumen to be a very optimistic
claim , and as I write this I don't know yet how close that claim is to
tested results . I will how ever say that this light is very well made ,
build quality looks to be excellent . The very first thing my brother
complained about ? He didn't like how smooth the body is , ok it
is a little on the slippery side . The lack of a surface that offers
grip is very noticeable . Apart from that this does seem to be a very
good flash light . So perhaps its time for some test results .
Current draw was measured @ 1.8Amp - The two
mode switch is built into the tailcap so I can't measure low current
draw . ( Sorry Folks ) Anyhow , 1.8Amp @ 3v or so is around
So what did I measure at the light box , about
350 Lumen .. ( 350 ...... ) I thought something might be
wrong ,, So I pulled out a few other flashlights of known performance
and the light box checked out ok ... ( 350 .... )
Oh right , low mode .... 30 Lumen in low
mode ( just in case you were wondering )
Now everything I said about the 250 2xAA holds
true for the 700L 6xAA . The build quality is excellent , the body is
smooth and slippery . In fact it's just a larger version that pumps more
light . Due to the design , there are two rows of 3xAA batteries and
some connectors to allow power to flow .. I'm just wondering if I can
get a current measurement ?
Sorry , its a no go .. It is a ruther
funny arangement and I don't wan't to kill the light ( It's my brothers
So here is measured output :
On high I measured 850 Lumens ( there seems to
be a lot of sag on high )
In fact I think it started @ 900L and within
about 10 seconds was down to 850L and continuing to go down in output .
Perhaps not the greatest heatsinking going on ?
In low mode I measured some 100L , which is not
that low really ..
The 2xAA ( 250L ) certainly seemed to impress .
The 700L 6xAA did not impress me that much . I really don't get
impressed these days by lights that suffer output sag . ( I think the
700L has cooled off enough to try a 60 second run )
60 second sag test = 950L Start with the light
nice and cool , after 30 seconds it was down to 830L and then for the
other 30 seconds slowly sagged to 800L . 950 start and after 60
seconds it was @ 800L . So the light output did stabilize some
what after 30 seconds but there was that 120L loss in those 30 seconds .
I would rather see a little less output ( designed ) and a lot less
output sag .
Anyhow Coleman has produced some very
interesting flashlights for the mass consumer market and I have to say
that the offerings are relatively good . I hope that Coleman will
continue to research and develop their flashlight technology so as to
improve the product and hopefully have something that can compete with
what is already in the market place .
What really impresses me about both these
lights is that they use AA batteries rather than Li-ion . And this is
what modern LED lights need is a more readily available power source
that does not require enthusiast level involvement . Just pop in some AA
and go light something up without worry .
