The tint shift in the e21a is LESS pronounced that in any 219 emitter. And by a large factor.
But it is still not acceptable to me in anything but a TIR optics that can do proper color mixing of the outer green part of the beam and inner rosy one.
Unlike just an ugly duv of an entire beam that can be corrected by a color filter, almost nothing can be done to tint shift.
In practice, however, this is critically important if you often use your mule at short distance, so that the entire beam is just in front of you. If you have a powerful mule to illuminate large area, then the green (and fainter) part will be somewhere at the edge of your field of view and you never tell it is there unless you look for it.
But in the end of the day I dont see a reason to use anything other than an optisolis or sunlike in a mule. For 21 LEDs, 6amps is just 300ma/LED which sn optisolis can survive forever
I used several mules with different emitters and for all practical purposes the tint shift at the edge is really not noticeable and will not affect picture taking. The beam is almost a whopping 180degrees wide and the tint shift is beyond your peripheral vision. The tint shift is beyond the field of view of even the widest ultra wide cameras.
I have no problem with Optisolis and Sunlike emitters as I’m sure it will have its own niche. But for the size it takes to accommodate 21 of those LEDs, we can accommodate probably twice as many E21A. Lumen Output would be many, many times brighter and run more efficient with the E21A.
I am sure that a light of given size would have a lot more power under the hood with e21a than that with those low power ones, thats pretty obvious. And for sure, for photography, when one needs just short flashes this power advantage is great.
I hope Jack will take all the time they need to optimize and tune the light before release. No need to rush. I will hold off on buying lesser offerings before this is available.
Sorry, I’m not quite understanding how the constant current buck driver will interact with Anduril.
Will the <6A ramps (while battery V > LED V) all somehow be handled by the buck driver (I’m assuming PWM given that it’s constant current?), and everything above handled by PWM on the FET driver? In which case, it would essentially act like a massive and more efficient version of a 7135 chip? And in which case, wouldn’t the lowest modes have quite poor efficiency from having to smoothly PWM all the way down from 6A?
I’m working with limited driver/electronics knowledge here, so please correct me if any of my assumptions are wrong.
You may or may not get an answer from them on this but here is another buck+fet anduril driver (lume1) from one of our members:
In the case of lume1, for batt V > LED V the buck portion takes over and has no PWM with max 3A current. Above 3A your only option is full FET (so no PWM here either).
Looks nice. Not really a budget flashlight though and out of my price range but if it gets REALLY spectacular reviews maybe after I get past Xmas and get a good coupon discount.
I wonder what their reasoning was in using XP-L2 HD
I think the era of dirt cheap stuff from China is passing.
