    Maglite Mini with Nichia 219 4500K HCRI?

    I received the module - the beam is terrible! haha. I have an older terralux dropin with the SSC P4, and the beam on that one is much better. I had the idea of spraying the reflector with some clear spray paint for a DIY-stipple. I've done that before with pretty good results. I haven't...

    Maglite Mini with Nichia 219 4500K HCRI?

    I just ordered that new style TLE-5EX with the xp-e. I will try to reflow either the Nichia 219 or an XP-G onto it.

    The Real Reason for Throw - an in depth examination

    dymonite I agree with everything you said, up until this point: ...but the current definition of throw makes no mention of how the light from the light source is being directed. Indeed, the definition could apply to a totally omnidirectional light source like the sun. I don't really like the...

    The Real Reason for Throw - an in depth examination

    The following is an informal (and probably incomplete or incorrect) proof. I ask that you all evaluate the assumptions and conclusions I make: First, two important starting points: 1. Not all light is visible (such as infrared). For the rest of this post, "light" means "visible light." 2. Since...

    The Real Reason for Throw - an in depth examination

    So? What is brightness if not the visual perception of the density of light? If you have more photons packed into an area, you have higher brightness. This is a suitable definition for both flux and lux. All other factors the same, yes it does. Not true. When people have very bright flashlights...

    Benson, I'm not trying to redefine brightness. I don't really understand what you are saying.

    The Real Reason for Throw - an in depth examination

    If I said I have a thrower, what do you think? DBS, Tiablo, DEFT, etc. etc. Right? Why? Because you are familiar with the beam pattern as being "throwy." When I said I have thrower, did you think maybe I really meant a floody light that could be used in some cases to illuminate a distant...

    The Real Reason for Throw - an in depth examination

    At this point my interest in posting in this thread is waning. I don't know if I'm just not being clear enough or if my perspective is totally wrong or if you guys just aren't getting it. I feel like I'm repeating myself. Here is an example, one last time, for the record: You have two...

    The Real Reason for Throw - an in depth examination

    No, I really did mean Lux =/= throw. I think my example on page 3 is pretty clear. Yes, that is what I'm saying. I don't know what the MW arc light is, but I think your example is in line with mine. I think the definition of "throwiness" you gave is pretty close to CPF common usage. Kengps...

    The Real Reason for Throw - an in depth examination

    Stop ganging up on me! :tinfoil: Yes, in the real world we are more often constrained by flux than by factors that affect beam pattern (it won't be anybody's EDC, but you can make a reflector 4 inches wide). But if we are trying to create a definition of throw, we cannot only consider today's...

    The Real Reason for Throw - an in depth examination

    If "throw" is simply a measure of distant object recognition, then it's possible for lights with a floody beam to have throw. That means that in some cases, flood = throw. When words can be manipulated, they lose their meaning. The term "throw" must take into account the beam pattern for this...

    The Real Reason for Throw - an in depth examination

    No, I didn't assign importance to one or the other. As I said back on page 3: "throwiness" is most certainly not a synonym of "usefulness." The point I'm making is that you can have a very bright flood light put more light on a target than a light with a tight beam. But McGizmo is right in that...

    The Real Reason for Throw - an in depth examination

    That is exactly my point, exactly! Nobody would say the sun out-throws something like the a Tiablo. There is more to the subjective term "throw" than simply number of lux on a distant target and the sun is a perfect example. Some lights (and the sun) have a broad distribution and tons of lumens...

    The Real Reason for Throw - an in depth examination

    You guys seem hung up on Lux on a surface at distance X. But that's not a measure of throw, that's a measure of illumination at a distance. You can't consider a flashlight a good thrower unless a lot (most?) of its light is being projected in a narrow beam. That's why the definition I gave takes...

    The Real Reason for Throw - an in depth examination

    Re: The Real Reason for Throw-an in depth examination First of all, does the OP of a thread have the authority to decide who gets to post in the thread? This begs the question: who is the owner of a thread; the original poster, the community as a whole, or the person *cough* Greta *cough*...
