Link? ALl I find is a scandinavian site selling a multi-LED lamp to be mounted on a skiing helment https://www.tromsoskiogsykkel.no/ski/utstyr/lykter/moonlight-bright-as-day-10000-hodelykt
Try this: https://moonlight.global/headlamps
They are sold with headband as standards AFAIK. When I bought mine, the helmet mount was extra. Not sure what is in the standard package right now and the website is lacking a lot of info.
