What is the lumen output of a 70watt Metal Halide Recessed Down Light Since majority of the light output is through the reflector area in the Down Light you want to know the total reduction of light?

Typical LOR (lumen output ratio) of a reasonable MH downlight would be around 0.6 meaning that you get 60% of the lumen output of the lamp out of the fitting. Any manufacturer should be able to provide the LOR for a particular fitting

Can reflector telescopes detect objects in space that do not give enough light to be seen by an unaided eye?
Yes. For example, I can see the moons of Jupiter through my 6" reflector which I cannot see unaided.
