Has anyone tried an LED panel flash replacement unit for still
photographs?

They seem to be popular when shooting videos, but not much has been
said about using them for stills.

They range in price, but here's an example at $40. It's listed as a
"Video Light" for a dslr, but obviously could be used for stills.

As best as I can figure out, they are always on when turned on and not
on just when the shutter is activated like a flash.

LED efficiency is inversely proportional to power. Pulsing them at high
power doesn't make them any brighter - just hotter. $1000 of LED chips
would build a mediocre powered flash.
