Output at very low currents and efficiency

[barjon]

I finally made few pictures, they are on the original post here :

Another Dynamo bike light (front + rear + standlight)

Finally, few pictures of the build. The plastic case contains the main circuitry, based on Pilom 9. It has 2 switch : 1 general, and one to choose slow/fast mode (see pilom). The light itself is made of a convoy s21a host. Inside, is a triple nichia 219c 4000K, with a carclo 10510 (20 mm triple elliptical) [boite] [ensemble] [tete]

For the standlight, I think a TPS6980X (X being 2, 5, 6 or 7). TI webench gives me this design

Anyone knows where the PCBs can be found ?
