Questions before you buy
How do I confirm a Millertech headlamp model?
Check the product label, packaging and official listing for the complete maker name and model identifier. Match those details before ordering accessories or replacement parts.
Can any headlamp strap attach to a helmet?
No. Confirm that the lamp or accessory is intended to mount on that helmet and follow both manufacturers' instructions.
Which battery type should I look for?
Choose a battery system supported by the exact lamp. Follow the manufacturer's guidance on compatible cells and charging.
What specifications help compare headlamps?
Look at beam pattern, runtime by mode, controls, weight and mounting options, with the intended activity in mind.
