The next lower setting is 70% - it would be nice to know just how bright that is.
I ride off road and only use Full power on our lamps when it gets downhill or over tricky terrain, but that is also where the helmet lamp comes in. For normal riding-we cut down to a couple of powerful 1w LED's- Cateye EL500 and EL300, and find these adequate. Then there is road use to and from the trails, and just cut down to the EL300. Providing the Full power is only used when required- I think the Blackburns will stretch. Put it this way- forget the Cateyes as they have a 25 hour battery life- but our 20w only has a 2 1/2 hr life. By switching on and off we can do an 8 hour ride and still have full power at the end.
I have used a single 3w as a helmet lamp and that was good. 2x5w sounds better and the Exposure is very good- but expensive. You do get what you pay for- but I do think I will have to go for the Blackburn thanks to finances. Then as finances do increase- I can always get a spare battery pack if I find I am lacking in Length of Power.
