This smooth reflector along with a dedomed emitter or XP-L HI is what you need to build an L6 "thrower". Warning: without modifying the reflector base, you will be disappointed in the resulting beam. A good beam can be achieved with this reflector, but it requires some work and tuning.
Here are my steps to achieving good focus with this reflector using a domeless emitter:
- Ensure that your solder joints are flat and smooth. You need a flat surface so that the reflector can sit down as far as possible. Use 22 AWG wire (18 AWG is too large to get flat enough).
- Discard the white XHP70 centering ring and instead just use a flat plastic insulating gasket.
- Sand the central raised portion off of the rear of the reflector. Then evenly sand the rest of the reflector base to approximtely 50% of its original thickness.
