While these two lanterns look very similar on the outside, they couldn't be more different on the inside.

To reduce the cost of our smaller AlpenGlow 250 lantern, we have internal light guides which pipe light up and reflect out to the lantern lens along the way. This allowed us to use a single printed circuit board in the AlpenGlow 250, while the AlpenGlow 500 leverages a total of 5 printed circuit boards.

Light uniformity and optical efficiency tuning was a blast, as I was literally media blasting prototype light guides by hand, to gain confidence on a proposed strategy; balancing lighting performance and experience at a given cost structure.

Pushing the limits of far field ultrasonic welding, we were able to join the overmolded lantern lens/diffuser to the bottom housing without adhesives or fasteners.
