Average light, better than nothing,
This review is from: Topeak Headlux Helmet Light - (Sports)
Bought this for my daily commute and am happy enough. It seems bright enough although I have seen brigther (think if you want brighter go for individual front and rear). I pulled off part of the strap when mounting so not the highest quality, but did get mounted in the end so decent enough. You need to ensure you mount in the correct position to be seen from front and rear (in your normal position) which may take a couple of attempts. The light has three modes - first on/rear flash, both flash, both on.
Main thing I noticed was the batteries drain in no time, I go through a set a month. It ia not obvious when the batteries drain, I originally thought it was broken - I had it so btoh lights flash which worked fine when I turned it on but by the time I got to work the white light wasn't working but red was. In the evening when I turned on both worked again but by the time I got home only red was on as before. I would have expected them to get a little dimmer to indicate the battery was low. I took the first one I bought back not realising it was the batteries but the second does the exact same. I eventually bought a 12 pack of batteries 12 X Panasonic CR2032 Lithium Cell 3V Battery Batteries, DL2032, BR2032, KCR2... for a couple of pounds which should last another 6 months as it takes 2 batteries. I would say the battery life must be around 15-20 hours tops, which is probably ok considering the size, I just notice it more as I don't need to change the ones on my bike anywhere near as often even though they are on at the same time.
