Dwight, it would be way too simple if everyone used the same measurement units or the same standards for expressing how bright the light is.
As I said initially, the light I have is advertised as 800 lm. That is a lot for a little light like this. I think it is quite bright, but everything is relative. I don’t know, really, how far it would light up an object. I never tested this. I am much more concerned (when I am biking in the woods) about very good illumination of objects that are fairly close (the rocks, the roots, the trees). In fact I carry two lights; one on the handlebar and the other on my helmet. One shows where I am going, the other – where I am looking. It is a very bright light, but I am afraid that it does not hold a candle (;-) to some of the big spot lights like the ones that others were talking about. I think that the biggest issue is not necessarily the brightness, but the reflector (quality). As someone mentioned, you want to have a very narrow beam (I am just waiting for a laser application) or you risk getting all kinds of reflections off the boat’s rigging. The biggest advantage of the little light like this is that it is small, reasonably inexpensive and it can point (easily) where you are looking (you can wear it). The one I have comes with a lithium battery, so it keeps its voltage quite well (months if not used).
