..and if you put an incan bulb inside a reflector for an LED it would probably not go well. Why would you expect it to work well when you're mixing parts that weren't designed for each other?

A "more focused beam" is generally called throw. Its a measure of how far the flashlight can project its beam of light. There are two things that come into effect:

1. The reflector's ability to gather light and basically make those light "rays" from the emissions source go in a parallel line or focus it at a distance.
   
   
2. The surface lux of the emission source.
   
   Incandescents have a filament. Their light comes from a squiggly wire of some sort. No reflector will ever gather all that light properly. LEDs are much closer to the ideal "point source" where all the light comes from a tiny spot.
   
   I think your eyes are lying to you. Incandescents just do not out-throw modern LEDs. They can't make as much light and they can't be focused as cleanly. HID and other arc-lighting can with a big enough reflector, but not incandescent. Maybe what you're seeing is a smaller hot-spot of light. That's possible. But the intensity of that hotspot is very relevant to how much throw a light has. You can buy a $26 light meter and test it yourself. Or you can believe me, because I've got lots of lights including incan maglites, LED maglites, and proper contemporary LED lights. And I own a light meter.

I use this with a lux to EV table and an EV chart to expose for my large format stuff. It's not great, but it works. In the future I'm going to build my own - you could try that, it's quite simple. A microprocessor like an arduino and a photoresistor, or for better accuracy a dedicated light meter board (about $10).

i think i have to retract my "idiot" comment, you're clearly way too smart, but maybe over analyzing bro, the meter sees the light, that's my ONLY point, it's just a matter of how to properly gauge the reading....since you're a light expert, please enlighten me on this subject so i can properly use my cheap ass meter on my full spectrum LED lights, I'd appreciate that

Actually I did. I purchased the one that u/Ohseventyfive recommended and got way better results. Hope this helps you as well man!

Never used Recharge before, so can't really speak on that, but yes, the lux meter is fine with the QB. I have the same board and I used this [meter] (https://www.amazon.com/Dr-Meter-LX1330B-Digital-Illuminance-Light/dp/B005A0ETXY/ref=sr_1_1_sspa?ie=UTF8&qid=1538762008&sr=8-1-spons&keywords=lux+meter&psc=1)
