Hi Ivana!

Funny you should mention this...I had mine blow out (Lumotec oval plus) with a Schmidt SON after only 1 1/2 weeks of riding (at roughly 28 kmh avs) commuting to work and back.

I had a nice discussion with one of the guys over at Schmidt, and he suggested using extra diodes in the lamp, OR to go and use a higher voltage lamp.

I've been thinking about putting in an extra lumotec into the circut anyway.

Did you get the Lumotec from Schmidt? They apparently beef up the light. Also, do you power a rear light off your SON?

ride safe,
Tom
