There's a lot of talk about front lights and brightness at the mo. But it's very difficult to make comparisons, given that manufacturers give photos, wattage lux and lumen values. So, hows about- We do our own comparison? If we can post pics of our own lights, taken under as near identical as possible circumstances, we can then post them up on this thread, which will make CC the site of the best ever comparison. Some ideas- Take photos of at least 2 lights you have. That way, it will hopefully give us more of a control over differences in camera quality, exposure etc. For example, I have a Cateye EL500, EL530 (thanks bonj!) and BLT Ozone 21ne. If I post pics of all three, and someone else posts two different light pics which include say an EL500 in their pics, we can then compare the 5 lights. Use fresh batteries. I suggest a pic of the light throw from your handlebars and horizontally aimed at a wall, say, 3m ahead. In the dark. Could we make this work? I know if we could it would be very useful. And we could always use ways of tempting more people onto the site.
