I'd like to know this too. I currently have a SON running a basic lumotec round halogen (2.4w) main headlamp, E6-Z secondary (3w) and Dtoplight+ LED rear lamp. I live in the country so need both headlamps. This setup works well but I like the idea of even more light and the automatic function. Best of all would be the reliability of LED. I don't mind sticking with halogen for the secondary lamp and would rather not make it obsolete as the E6-Z isn't cheap!
So, if I were to invest in one of these lamps would it be possible to keep the secondary lamp? Is the IQ so bright that I wouldn't even notice if I had it on?
Interesting question, & I've just tested it in my garage.
I've got the new IQ LED running off a bottle dynamo, which also runs an LED dynamo rear light(Seculite). I've just temporarily connected my old halogen 2.4w front light in parallel with the IQ. With the bike hanging from a rafter,I've turned the pedals in top gear at various speeds. At low speed, with the halogen disconnected, the IQ gives a very powerful light. If I connect the halogen while maintaining this slow cadence, the IQ dims noticeably as the Halogen lights up. At higher speeds, both lights seem to give full output.
This was a crude test, but it does seem that you can run a secondary light, ideally with a manual switch to bring it into operation only above road speeds where it doesn't affect the main light.
Personally, I'm more than satisfied with the IQ so I don't think I'll be bothering with a secondary. If I regularly did 35mph descents down dangerous mountain passes, I'd want all the light I could get, & I'd probably splice in the E6 as a secondary. Hope this helps.
