With those, it would have a bigger hotspot and more lumens but less throw. Potentially a warmer tint, too.
It should look good with XP-L HI or XHP35 HI, since they’re both flat and have pretty good color consistency.
However, SST-20 might not look so good. It could have issues with focus or tint, since it’s a taller LED and it emits different colors at different angles. Specifically, the green parts of the beam go sideways into the reflector, making the hotspot appear green, while the pink parts of the beam go forward out the lens into the spill area… which contrasts against the hotspot to make it look even more green. It’s similar to the Cree rainbow effect.
I don’t see any positive contacts which are close to a negative tube. Where are you seeing that?
Not sure. I’ve never heard of the T27 before. However, its specs say its beam is about 58% as intense as the K1, despite making almost 3X as many lumens. So it would probably be visually similar to the D1S, but with a higher turbo mode.
Pretty neat addition, the throwers in the Emisar/Noctigon lineup have been more interesting to me than the hot potatoes so this is nice to see. The cool white is a non-start for me though, but the samples of that LED I have seen have at least been very clean so should be quite nice for those who can tolerate such high color temps. I am curious how this would throw with a XP-L HI or XHP35 in it as those are available in nice tints and CCTs and realistically I can’t reliably see a mile in daytime for identifying anything anyway.
The hole in the beam from such close distance isn’t from having a defective unit, that’s just how well-focused beams look at close range. Having used an Acebeam T21 and Maxtoch X Pro modified with Black Flat and White Flat 2mm accordingly, I can attest to that artifact.
The second graph doesn’t make it seem too regulated on highest output? Unless the second graph is with the warm room thermal regulation as well.
But doesn’t a well-implemented regulated driver keep constant regulation regardless of cell voltage and resistance? Something like a Zebralight will make a cell that’s nearing 3amps still output turbo.
The graphs look like a direct-drive graph ie following the voltage sag of the cell.
No, you’re thinking of a boost driver which can step up the voltage from the cell. Zebralights use boost-buck drivers (which can both raise and lower voltage to maintain max efficiency), not linear.
Well hopefully a cell with less resistance fairs significantly better, because that driver might as well be run of the mill fet+linear based on the graphs.
Hank great job! Also ToyKeeper thank you for putting your amazing UI in another light. I think the lighted switch is awesome and the light seems very high quality. Now I need to decide if I go with the Osram leds or wait for something with more lumens…
You can think of the FET in this case like a variable resistor that adjusts its value so that it allows a fixed current to flow. And that’s a linear regulator.
