Do Smaller Emitters Throw Better?

Flashlight Optics - Dome, Dedoming and Throw

I wanted to write a longish text about flashlight optics for quite a while now, starting with all the optics and photometry basics, up to the details of what throw depends on and why, including how dedoming increases throw, all with a coherent line of argumentation and some experiments to try. I even started writing that document, but it seems I just don't find the time to finish it in reasonable time. I now decided to take a shortcut and just do a very short version of it, especially focusin…

XPE-2 versus XPG-2. Surprising results.

Hi all, Apologies if this has been discussed before. I am selling triple drop-ins elsewhere and I had someone ask me which emitter between the new XPG2 and XPE2 had the better throw. I nearly blindly responded with the XPE2 given the original version was a better thrower than the original XPG. Instead I looked back over the datasheets and noted that while the original XPG had a beam angle of 125 degrees, the new emitter had cut this down to 115 degrees, while the XPE has gone from 115 degrees …

Zoom lights vs Reflector lights

Hi. I have written some general information just because I have a lot of other things I should be doing and my addiction to lights is how I procrastinate. I am not so sure that my technical understand is 100% correct and therefore would like to ask that you comment on this. (in a nice way please) Before we start please take note that I am in South Africa and shipping to US is crazy so don’t think I am here to sell. My on-line sore also does not accept international payments nor Paypal so don’t …
