I think we're on different wavelenghts here. I didn't know cree were making XR-E Q5's and XR-C Red's in 1995.:duh2: You have to compare apples with apples.
They weren't, I did not say they were.
most lights will produce some red that becomes quite visable when the remainder of the spectrum is filtered out however not all of these would be suitable for the usage as requested by the original post which was about finding deer in the wild with red light, this is a lot different to finding your way in a room
My initial post was in response to lxhunter's observation that - "As a result the red filter blocked almost all the light."
Obviously in retrospect I should have quoted his post as you seem to have become somewhat hostile, and assumed that my post was in response to yours due to the juxtaposition.
irrespective of the emitters, how does the NDI with a small reflector + filter provide greater output when compared to either a Derelight DBS or a Tiablo A9.
It doesn't, and I did not say or imply that it would. I mentioned it by way of example, assuming that with a modicum of thought, one might infer that filtering an inherently more powerful light than the NDI would likely yield a more potent result.
Put a modern Cree XR-C Red red emitter (not a 14 year old red emitter) in any of these and I know which I'd use for deer spotting
So would I, but if one didn't want to modify a light, one could at least try a filter first and see if it would sufice.
