Asked maukka about making some sunlight spectrum CoB led review. Guess he will say something in a while.
I understand they may not break any luminous intensity record. However, with a decent sized reflector they will still be suitable for short range lighting, at the very least.
Hi Simon, I am very interested in flashlights using monochromatic light, e.g. your new C8+ using Osram's KR CSLNM1.23. Did you measure the output in lumen yet? I wonder if 2.5A is its sweet spot already or if it can safely be driven beyond 3A with signicantly more output.
For comparison:
I have bought the Amutorch New VG10 from Neal Zhang. It's fitted with Osram's Ostar Projection Compact LE Q8WP. It has 3 modes only (Low-Medium-High). For the naked eye, there's barely any difference to see between Medium and High mode. But on High mode the lights draws 5A from the battery. The head unit gets fairly hot within a few minutes.
I think there is no problem at all to increase the current to 3A. The mode of my driver sample is 30–100, but visually the brightness difference between the two modes is very small. I consider only providing one mode 100% or two modes 10–100. I don’t know about hunting. I would like to know if 10% mode is useful for hunting. Or is a 100% mode sufficient for hunting?
100% mode is NOT sufficient for hunting. Having a LOW is important.
I wonder if there is a visible difference between 10-20-30% as Simon mentioned.
SOS: I personally find hidden RED Strobe or SOS or beacon, quite useful.
Our car always breaks down in the wrong place and using a RED flashlight blinky instead of the car blinkies preserves the car battery . Of course it could be Hidden but very useful. on the other hand WHITE strobe is annoying.
For photographers 10 to 100% is too big a step. I prefer the second mode to be at the point at which the light can run without getting excessively hot.
I sold like hundreds of lights to hunters, literarly all of them were single mode. I offer to put modes as buyer wants, they all say “one mode - 100%” and a few that I sold with 12 modes firmware returned for reprogramming sooner or later.
