Tint ramping, like “the interwet”, will never catch on.
But seriously, what’s the point? Instead of doing one thing well you’ll have a torch that does two things mediocre. I didn’t watch LuxWads videos, am I missing something?
… but now I wonder if maybe I should have ordered it with 2700K LH351D and 6000K Oslon White 2. That way in addition to tint mixing it would also have flood for close range and spot for long range.
It doesn’t do anything worse though ? You still have a quad emitter light with the same power capabilities (turbo is mid tint but I don’t think the tint matters much in turbo).
The manufacturing cost should be probably less than 2$ higher, Hank charge +3.6$ for the tint ramping D4v2, which is quite reasonable.
An advantage is the improved tint for a good part of the tint ramp for people who dislike greenish tints, this was already possible by requesting two different CCTs, but now the tint is adjustable.
For different emitters (instant switching) , for example flood and throw emitters, I would tend to agree, since it’s then a 2 emitters flood, 2 emitters throw light and won’t have the same turbo throw capabilities as a 4 throwy emitters light
Oh well, just may have to buy them all again. This is what companies need to do in terms of thinking out of the box. Making a brighter flashlight just does not cut it anymore.
I often carry different color temps throughout the day. Sst-20 4000k is nice right after the sun goes down. Then 2700k when it gets real dark. Mixing in the 2000k e21a did wonders for my sleep cycle.
Can’t wait for tint ramping dt8 in e21a. It would replace several lights.
Furthermore, W2 is under-driven in these 2 channel lights. W1 is a much better choice for throw, especially considering that you have a whole separate channel for flood.
You have to keep in mind though that underdriven Leds are very efficient. You’ll get 2500 total lumens or so from two W2s at 9A while you’ll push 1800 with two W1s. I’m personally willing to sacrifice the 20% less throw for 40% more lumens.
Where are you getting the 2500 total lumens from? Do you have a link to an output chart for W2’s I can look at? I’ve been looking periodically for several months but all I’ve been able to find is a graph for CSLNM1.
I typically use my lights outside and I prefer lumen driven candela (meaning high candela generated from sheer lumens) and sustainably high lumens. One of my favorite lights is the Mateminco MT04 with 4*SST40. It does 7000 lumens and 50k candela despite not being designed for throw.
I did some quick math to get an estimate. In the KR1, the W1 model gets 110 kcd at 5A, while the W2 model gets 100 kcd at 7.5A. In Hank’s four-LED tint-ramp lights, power is the same for either emitter type, so lux per Amp seems like the relevant value. That puts the W1 at about 65% more lux per Amp than W2.
Meanwhile, with two W1 driven at 4.5A each, total output is about 1800 lumens, while W2 gets about 2500 lumens. That’s about ~40% more photons, which is a big boost if you’re ceiling-bouncing the light.
If I did the math right, the W2 hotspot should look about 50% wider than W1, but only 60% as bright. Illuminating something to the same lux would take about 65% more power, and would have about 60% as much runtime, and would bump into thermal regulation sooner. Like, if W1 got 5 hours of runtime, W2 would get 3 hours at the same lux.
So for this range of lights, most people go with W1 as the throwy option.
