Just enter the lumens value to get the corresponding foot-candle value. Heads are interchangeable so you can just add one to your surefire body if you’re not satisfied. This is an online calculator to convert lumens per square foot to foot-candles. Modlite’s PLHv2 is a notable improvement over the Surefire. Stream light has a hotter hot spot and now candela are almost equal or more important than lumen as a performance metric. Surefire raced to 1500 lumens and got there first. But the easiest way to explain it is Surefire isn’t cutting edge in output performance and stream light’s development cycle is just a little behind surefire which allows them to compensate for Surefire’s latest products. Input your light source radiation angle or apex angle. Is the Scout meant to have a broader beam or what? Not sure I get the purpose when there are smaller, handier lights with more intense light for carbines. To use this tool as candela to lumen calculator: Enter your known value of candela on our calculator. I also have Olight PLs and they are also seemingly more intense with a great beam. Boasting 700 Lumens and 20,000 Candela, the FOXTROT2R produces a bright yet focused beam capable of meeting the needs of tactical professionals and firearm. I just expected a hot spot at least as intense as a 1000 Lumen light. But when you compare the beams, the scout spills a bit wider and seems less intense. ![]() ![]() ![]() 20000 Lumen Comparisons Lumens are additive, meaning they can be added together to get a total output of light. I bought the HLs some time ago, and but they COULD be 1000 lumens. So 20000 lm would be less than 20000 candela with the candela only quantified if the angle of beam width is known.
