I have a p60 host with an R2 Drop-in. It is using a op reflector and I have an aspheric lens installed. I get a very nice hotspot but i get rings in the beam like crazy. Will blacking out the reflector help this? Will it reduce my output? Will it increase my output?
I guess I am wondering if there is anyway i can make this setup better (while leaving the reflector in for now). All it is is a p60 host with an r2 drop in and an aspheric lens lol.
Thanks everyone!
Mike
I have the same setup in a Hugsby host mounted on my Mini 30, please post the results I would like to get rid of my rings also.
..you need to black out the reflector.
I made up a black paper cone to fit into the reflector, but any matt black paint will do.
How will that effect the output? Increase? Decrease? Remain the same?
it will roughly double. that's why i paint all my reflectors black. 
Just did it. Didn't really notice much increase if any in the output but the beam profile is a million times better! Thanks guys! Any other recommended tweaks?
I still have to toy with driver/drive levels etc. and i think i'll steer clear of the focal point distance etc. for now.
I need to do mine how did you do it?
Spray the reflector flat black, E. Aspherics don't like reflectors and the XR-E emitters work so well because of the 90° beam. XM-L aren't as good because of the 120° beam doesn't focus the majority of light on the center of the aspheric. Find a beat up reflector and paint it. You'll be amazed!
You just get some flat black spray paint, take the reflector out and spray it.
Regarding tweaks…you can paint the Cree Ring that is around the dome of the XR-E with that same paint if you are careful. For this you need to use a small brush obviously.
This eliminates that first large ring around the emitter in the beam.
Painting the reflector doesn’t increase the output. It just eliminates all those disco ball artifacts since a reflector in an aspheric doesn’t do anything helpful.
So to answer your question it doesn’t increase or decrease the throw of the light. It reduces the lumens that is just the lumens that are creating all those artifacts.
The reflector doesn’t send any light back into the focal point of the aspheric.
kidding aside about increasing output...removing artifacts/rings has a purpose beyond making it look more pleasing. when using a spotlight in fog/mist etc., you'll get much less scatter if there isn't any spill, and that can be the difference between seeing what you're looking for and seeing hardly anything but the mist...
