Glad you liked the video! I don’t do any commercials… maybe in the future!
Thanks for the suggestion! I gave it a try - There is not any coating that I can see on the lens of my light, and removing the lens did not change the color of the beam in any way. It appears based off this sample that Hank has listened to the feedback and changed/removed the AR coating.
Kinda disappointed to see the extreme price premium for the B35 options (and XHP35 HI to a lesser extent given the more expensive emitter). I don’t see that sort of bump in cost for switching drivers from competing brands, and unless this is a new design it doesn’t really knock it out of the park in terms of efficiency.
LuxWad - agree with everyone: your videos are fantastic and you now have a new subscriber, the informative yet relaxed (and honest) reviews are spot on
I have around 20pcs of B35AM and AR and they can sustain 1000lm without a sweat. Better find one and try so you’ll see how underpowered looks this initail video…
Hank's rating is 1400 lumens with the B35AM. Video shows 3.6 amps from a boost driver for a 6V LED, looks like 1650 at start, so maybe ~1500 at 30 secs. The light is 120 mm long, 40 mm head - nothing at all very big, think of it as a BLF/Eagle X6 but little shorter, or an Astrolux EC01 but slightly larger head diameter.
My immediate question is why limited to 3.6 A? Can the driver take 4 amps?
In my builds B35Am at 6V/4A turns a lot rosier than realy is so it’s on a max driving limit. Sosetting it on 3.6A is very good idea. Only stepdown is a minus
Cool! Sounds like the R&D has already been done on these LED's. Not clear from Hank's listing, but looks like the output binning varies based on the tint - lower tint, lower output. E700, E800, E900, E1200 shown in the store listing https://www.eurekatronix.com/product-page/nichia-b35ax?
So the 3500K is E700, 4000K is E800, 5000K is E900, etc.
Page 4 has the lumens outputs at 1.4 amps. Hhmm, might have to re-consider 3500K. 4000K jumps up to the next output bin, roughly 200 lumens more I'm guessing for 3.6 amps.
Sounds good to me. I typically use lights like this for walking the trails at night, and I usually stick between 5-20 lumens. Just enough to see down the trail without ruining my night vision.
My current go-to is a D80v2 with 219b and a 2A max regulated driver. The B35AM 3500K will probably more than double the max output of my D80v2.
Kaidomain. I wouldn’t exactly call their $24 XHP35 C8 a serious competitor to the DM11 though.
I think a better question is what does compete with the DM11/B35A? Perhaps the Acebeam E70/FC40? That’s the same price. The Zebralight SC700d? That’s considerably more expensive.
