Olight I3S-CU Polished finish: (made of brass)
LED: XP-L Cool white
REFLECTOR: Orange peel
BATTERY: 1xAAA 0.9-2.0 V (NiMH, Alkaline, primay lithium).
MODES: 3 HIGH/MID/LOW
DATE: February 2016
FROM: Olight I3S-CU hkequipment.net
Packaging, perfect for carrying the flashlight, to give away or to store the flashlight. Includes one alkaline battery ( I am not a big fan and, I will use with high quality NiMH aaa) and a Manual user, but I miss one spare oring.
The light not change the size of his predecessor I3s aluminium version, but the weigh is increased for the new material:
Some Pics now for comparisson with other "3 Series"; ITP A3 Eos upgraded (XP-G R5), Olight I3 (XP-G R5) and Olight I3S (XPG-2):
Now Pic with a Maratac aaa copper Rev3, my first copper flashlight, I am not sure yet if I will be a fan of copper lights....(but I love this Maratac!)
and with other well known aaa flashlights:
Some pics for detail of design; tailstand is allowed, the threads have a good quality and run very soft. The clip is strong enough for this little size. head to head with the auminium version, only 2 small external aesthetic differences:
Battery and Interface:
Information from Olight says; 0.9-2.0V, and of course I will no try 10440 on this. I prefer NimH and Primary Lithium.
Is a Twisty light (tighten and loosen head for changing modes).
No memory modes, always turn on the highest mode. The sequence; High,Mid,Low,High,..... (this I3s-CU has not hidden strobe as the I3S aluminium version)
A XP-L Cool white welll centered in small Orange Peel reflector. Perfect beam, more flood than his colleague in aluminium:
A animated gif:
Information about modes and runtime in high:
Official information manual:
First I put a small graph of relative power modes in % to get an idea of which is the distribution of modes. Considering that the flashlight has 3 modes, but how high suffers a drop in power "step down" programmed for 3 minutes, I have included the value of this step as a reference within the graph;
Runtime test in High mode with a Panasonic Eneloop NiMH min. 750 mA. One data for minute, for reference the 100% on this test is the highest value between 30 and 180 seconds (ANSI NEMA FL-1 standard).
In detail the first 4 minutes of test, one data for each 10 seconds. The step down begins at 3 minutes, slowly descent for 30 seconds to about 45% of initial power and then the line is flat:
I love the light, my score is 9/10. (for the price is a perfect 1xaaa, but I will prefer a diferent order of modes, my preferred for aaa lights is low/mid/high).
