Lumonite stays in the holder well, but the holder did not attach very tightly to all helmet models. Works best on models with a clear cap.
Already in use for the second year. A great lamp, with you at work and on your free time. Withstood frosts too!
Sure a good rack for a work helmet, but it didn’t fit my helmet.
With this better luminaire mount you can apply, versatile functions for mounting options
