60mm (D) × 50mm (H) reflector throw estimation

Advanced calculators for theoretical lumens, lux, beam divergence, and more, of custom LED flashlights

These are some advanced calculators I have made to help me estimate the final performance of the custom flashlights I build, and I decided to share it with you guys so you can do the same Some example screenshots: Aspheric Lens: [image] Standard Reflector: [image] Recoil Reflector: [image] . . Using these equations, it is possible to find: -candela (lux @ 1m) -throw (ANSI to .25 lux) -lumens in spot -lumens in spill (for standard reflectors only) -total lumens OTF …
