Beam good for Bike, Repair service ok Sep 01, 2009
By Hugh Macdonald
"computer magician"
The newest version of this (I own 3) has a frosted lens giving a more diffused even spread light beam. For my bike I liked the old brighter "spot" in the middle to focus on some pothole, but the broad even spread is probably better. It is a bit yellower than the old one which was blueish. No other 1w units (I have three from China) have as even a beam -- although the last one was close as it seems Luxeon now supplies a pretty good lens with their leds. Non-Luxeons are not as good.
The best feature about the EOS is the regulated light and the button on/off action. With EOS you set the mode, bright, med, low, blinking at the startup. Then after 2 seconds another press of the button turns it off. This is how you want it if you turn it on, use it, then you want to turn it off. You don't want it cycling through all the remaining modes until you get off. You know for sure after a few seconds that a button press turns it off.
The best of the cheaper China versions always cycles through the modes. Starts at med, then high, then blink, then off. Starting at med is better than the EOS starting at bright. Med is brighter than most one or two or three led headlamps -- I tried them all in a store. The China ones have to press through each other modes to get it off.
The regulated light means you consume a fixed 250 ma for hi, 80ma for med, and 20 for low until the battery becomes too dead to supply this. When the batteries can no longer supply 250ma (on hi) the current will drop lower and lower until it is no different from med and eventually low. I use this to tell me how the batteries are doing: If there is no difference between hi and med I know the batteries can only give 80ma -- time to get a recharge.
I use rechargable NiMh 800 or 1000mah AAA batteries. While lower in voltage they supply the current better. Use the low self-discharge types if you want it as a flashlight, i.e. don't use it all the time. HOWEVER, when they get weak they will go dead soon! Alkalines fade slowly.
The battery case is superior, easy and high quality and easy to open (compared to China versions with easy to bend battery contacts and non-waterproof button and hard to open case).
One EOS unit's switch failed. I had to google to find out how to send it in -- they need an RMA. The info is on the package also. Once over the bureacracy hump, they replaced it promptly. The China units have no guarantee.
Good for average user / good for geek Jan 17, 2012

I've got 70 lumen version. It well built, pretty powerful single LED headtorch. For quality, and "made in USA" badge, I think it is also not too expensive.
I am planning to upgrade it with Cree XP-G LED to go over 100 lumen - it is quite easy upgrade, you just need a solder. :-) Another nice thing is that you can play not only with LED but also with optics. Don't like diffused beam? Why not change diffusor to give you spot? Or maybe beam is not wide enough?... ;-) I think this torch is perfect for modifications. But even if you don't like playing around, you would be happy with what comes out of the box.

This headlamp has the power to shed light on things near and far. Don't worry if it starts raining, it's waterproof!
Great lamp Nov 07, 2010
By Michael Beattie
I took this lamp camping and it is very good. I find the lowest of the 3 continuous modes is more than enough to see what you are doing at night. The brighter ones really light things up. It is very durable. It seems that the batteries will last a while. I used it a couple of nights and it seems to still be going strong.
