Interpreting specification of a rectifier

[seanspotatobusiness]

I took a rectifier from a trashed printer power supply and it's part number is SIVB A60. I was wondering whether I could use it to rectify the current from my bike dynamo to power some LEDs (I'm going to DIY upgrade it from it's stupid, overpriced incandescent bulb) but I'm worried it might actually be a wasteful component. The data sheet says max forward voltage is 1.05 V. Does that mean it would be dropping 1.05 of my precious, precious volts (in which case I might make my own more efficient rectifier)?

Below is an excerpt from the specification sheet I found online.

Hi,

Yes, the 1.0V at 0.5A is lost.

There are Schottky diode's with lower forward current.
Or ICs called ideal diodes.
