No idea. The only pics that seem available so far look to be the promo stuff from the company.
I'm not even sure exactly how it fits together. Do the headlamp portion & the battery pack snap together & then fit into the bottom of the lantern? It's hard to tell from the pics.
Still it's definitely a product that might be worth keeping an eye on.
Edit: FWIW Looking at closeups of the headlamp portion the supplementary LEDs look to be power LEDs rather than 5mm.
