The Olight I3E EOS Copper, a small keyring torch which is operated with one AAA battery and has a capacity of 120 lumen. The Olight I3E EOS comes in a really nice plastic box and is welded air-tight to prevent a patina, the whole package is also very nice as a gift. I`ve bought mine over here: http://stores.ebay.de/Olight-Direct-Official?\_trksid=p2047675.l2563 or you can buy directly at: https://www.olightstore.com/
A battery and a split ring are included, at first sight the lamp looks like a little jewel.
The copper version is heavier than the colored I3E models but it feels just right and very solid. The whole flashlight is machined very cleanly and the surface is completely smooth and not precoated, so it will oxidize really fast and the torch will very quickly get a nice patina. Twisting the head turns the light on in one mode, thats it 
, a very minimalistic but useful flashlight! The square threads feels very smooth and works like a charm.
The first and only mode is very bright, 120 lumen with an Philips LUXEON TX LED with a TIR lens and a neutral tint. After 5 minutes it was reasonably warm but not hot, so the heat management seems quite good which is also due to the copper.

I really like this tiny light and for myself I usually prefer small keychain lights with at least 2 modes , a low and a high mode. But the Olight I3E EOS lives from the fact that it is so handy and small you can take it everywhere, I always carry it in the fifth pocket of my jeans and use this little gem daily. It would be nice if there was a clip for the lamp, it would be helpful as an anti-roll device and because there is no knurling, a clip would make the lamp also more gripping…….but these are just small things you do not really miss.
In addition, the price performance ratio is almost unbeatable, other torches of this size of copper are usually substantially more expensive and larger.
