it will help scatter light into that dark zone and improve matters. They all seem to have a very slight dark centre even with peel but with peel it's so slight that it becomes invisible in practice except on a light coloured wall (and that's coming form someone who's very sensitive to dark centers).
No, not necessarily. You can use a rubber pad, something along the thickness of a tyre tube. One of those jam jar opening pads one's wife has will work too.
JaguarDave-in-Oz -- :thanks: for the bezel ring removal advice! Following your suggestion to use a rubber pad I was able to get it removed. It was a little tricky getting the reflector out after I removed the bezel ring because of the clear silicone o-ring that was inserted around the outer top edge of the reflector but by patiently using a couple of pocket knives with small blades (on the
outer edges of the reflector, of course) I got it slowly worked up and out of there.
After I got the reflector out I'm thinking to myself, "why did you remove the reflector when you don't have a replacement reflector to put in there" :thinking:
I guess I'm all practiced up now so when I get an OP reflector I can install it.
Anyhow the emitter sets on a disc that is sort of a phenolic material and I was surprised that the disc (and emitter) move around if the disc is touched. Hopefully there is some thermal paste under there!
I may be wrong but I think if a person had a
very thin metal washer (shim) if placed underneath the reflector it might eliminate that dark center in the hot spot. I'm going to experiment with that idea.
Thanks again for your post!
