Comparison
Short answer: HeliosX headlights cost $495–$835, against $3,500–$5,250 for the RONIN X7. They weigh 164–231 g with the battery on the band, while the RONIN X7 puts 233 g on your head and its battery and holster at your hip, about 633 g in all. Canopus reaches 198,000 lux, Arcturus runs up to 12 hours, and every HeliosX light has a 5-year warranty against RONIN's 1 year.
RONIN makes a high-output headband light with a battery worn at the hip. HeliosX headlights put the light and battery on one band, with no cable to route, at a fraction of the price. Here is how they compare on the numbers each company publishes.

The differences that matter
Choose HeliosX for a headlight that costs $495–$835 instead of $3,500–$5,250, carries its battery on the band instead of a cable to your hip, and comes with a 5-year warranty instead of one.

RONIN publishes higher peak output. HeliosX headlights are built for a full operating day: Canopus reaches 198,000 lux, Arcturus runs up to 12 hours on a charge, and Antares ships with two batteries so one is always charging. Every HeliosX headlight has an adjustable spot.
