UV battle: S12 buck/boost v 3 x M21A

3 x M21As can fluoresce opal across a brightly lit room. Note the longer phosphorescence, too, in the darkened room. Not really a fair battle, but that’s what I grabbed. Will try these 3 x M21As outside tonight for a bit of fun, but not for long bursts due to my melty zip ties temporarily in place.
