Lights for night cycling

"Formerly posted by Maxxevv: Almost all the 'affordable' single led lamps that rate above 1000 lumens are overated. If you look around on the web, from people who have actual lumens measurement devices, they are in the range of 600-650 lumens only.  The better ones only achieve close to 900 lumens. So far only the really expensive lights do have close to the claimed 1000 lumens. And that with the condition that heat is properly displaced.

Practically though, even off road, 600 lumens is quite suffice if the light spread is good and even.  But problem with most of these 'affordable' lights is that the lens design is not quite there ... hence many resort to using 2 for offroad use to get the appropriate spread.

As for white versus blue .... try looking at them from 200 meters, the blue light will be significantly less visible for the same light output.  If you value your life ... then you should know the correct choice.

agreed about the cost of actual lighting and the actual claimed rating which may be overstated.
You pay for what you get.
i bought an expensive light from moon (1500 lumens)
and another for my road bike (niterider 300 lumens from hup leong)
i find for road is good to use 300 lumens with blinking for riding at night to get attention of lorries and other vehicles.
it may irritate other on coming riders but its not as bright as cars HID or daytime driving lights. better safer than sorly :P

Bright lights need, at the very least, lithium ion batteries.

Last month, I bought at a budget shop, one that is bright enough to see the road like a headlamp where the street illumination is inadequate. Then I bought a second one. One tilted to focus closer range than the other. Last week I just realized they already flattened the 3 AAA batteries in each of them. Batteries can last very much longer with these front lights switched to faster blinking mode. I had them in constant/flood-lighting mode. Next time buy size 'D' battery to power them?

is there any difference between white light and blue light other than their colour?
