This light is of a customer of mine.
It has a square inductor. The inductor is in the middle and is a square with the corners cut off. These inductors were only on the earliest of Stenlights. On the later ones the inductor is round.
When I started this I didn't realize that there were any square inductors.
What happens is the the reflecor makes contact with the square inductor before it fully seats.
In a round inductored Stenlight you have to wiggle the reflectors around a little and they will eventually drop in. No force is needed and should not be used.
With the square inductor the notch needs to be ground into the reflector where it contacts the square inductor until it will fully seat over the LEDs. Here is where it gets difficult to make these fit all square inductors. We are finding that their is a variance between square inductors. We notched several of them then found that a couple of people had to take and exacto knife or file and take off a tiny bit more metal to get it to fit.
If you are handy with tools it is not that big of an operation to get the reflector to fit the square inductor. Just don't force it into place.
I will come back afterwhile and provide installation instructions.
