This TTArtisan Mini LED Light looks like a classic 135 Kodachrome film canister, is magnetic, mounts on the cold/hot shoe (perfect for the Panasonic S9 which only has a cold shoe), holds between 80-160 mins charge depending on the color temperature you use (6000K/4500K/3000K), and recharges in 45 mins.
Of course, it is just a little more powerful than your smartphone light, and don’t expect it to replace a proper camera flash light, but I see myself using it as a fill-in light (portrait, macro) — or even as a keychain (larnyard optional, not included in package).
