For a thrower, I see only 600kcd+ as an option…
In fact,I wonder if someone in the aftermarket will boost the 650kcd number…I haven’t bought one yet due to the new car, but it’s at the top of my list… we
Nice beamshots, made an account registration for those
But you are completely right, i have a L21A with white flat and 5A driver, does about 550+ kCd so its very compareable, its real fun, but not very practical (or should i say useful ?)
I won’t order W1. I find cool white throwers have more visible backscatter, I don’t find ultra-tiny hotspots all that useful, I’m tired of linear drivers, and I haven’t yet found a light that throws far enough to make me stop caring about CRI.
I’m waiting to see how the XHP35 HI model performs, especially if Hank sources some of the 80 CRI Easywhites, with which I’ve had very good results in other lights in 4000K and 4500K. Barring that, I’d consider SST-20.
All of the Emisar lights use Linear + Fet drivers. The Linear part of the driver is responsible for the regulation which many of us seek in a light.
I believe Zak’s comment was extending beyond the Noctigon line of products, and I too agree, waiting to see more buck and boost drivers and limit my purchases to these flashlights as well.
I meant: what i the reason to take the XPL-Hi over the XHP35? I don´t see any. If throw and tintshift is comparable and XHP35 makes more lumen, i would always choose XHP35.
Ah, right.
XHP35 HI doesn’t have a tint shift either. I guess the main reason would be price.
ADDED:
Maybe tint selection as well. Maybe longer runtime / turbo time? XP-L will surely not need a thermal stepdown. XHP35 HI might.
The no-PWM linear driver in the K1 should be a bit more efficient than a 7135-based PWM driver. If the 7135 design has multiple channels though, it’s only a small difference.
A direct-drive FET is also frequently a nice addition, to increase the maximum brightness on lights which can actually handle the extra power. It’s mostly just for turbo use though.
Compared to a linear driver or a linear-plus-direct-drive hybrid driver, a boost driver typically is more efficient in the medium modes. However, it’s usually also not able to go as bright as a FET turbo, and tends to be less efficient on really low modes too. So, not as good for moon or turbo, but usually more efficient at most of the levels in-between.
There are some known cases where a boost or buck driver ended up being less efficient, like how the Lux-RC 371D driver is ~30% less efficient (even in medium modes) than a simple amc7135 driver… but that doesn’t seem to be the common case.
