Juki TL-2010Q LED

For the record, Juki thinks this SMD LED provides enough light around the needle of Mary’s TL-2010Q sewing machine:

The 30 Ω resistor drops exactly 2.0 V, so the white LED runs at 67 mA.

We think it’s a glowworm, compared to the COB LED bar across the back of the arm:

I can do better than that, although not with juice from their 5 V power supply.
