Emisar D3AA is available now

It’s not the full review, but here is my first look and impressions of the DM11 (Nichia B35AM 5000K).

The review will take another couple of months or so, I will have to get another with a different LED. I’m not sure which is better, SFT40 or XHP35 HI…

Do you work with commercials? You should work with commercials. I’m sold!

Crap! I really want one now... I mean the camera

Hank are you going to stock additional DM11 optics on your components page?

The one on the far right is what I’m using in my dev host. Or perhaps even more floody, not sure exactly which optic it’s using. It’s a nice beam, but it’s not very throwy at all. And the host is pretty scratched up and had some manual corrections to the shape. So it’s great for dev purposes, since it’s functionally the same as a production model but not in good enough condition to be sold to a customer or sent to a reviewer.

This looks like a nice upgrade! :smiley:

It might help to check the lens, and maybe polish off the AR coating. Hank said your light is 99% the same as a production version, and the lens might be that other 1%. I noticed the coating on my dev host was different than his other lights, and gave the beam a green hue, but he said that’ll be fixed in production. If that affects yours, you should be able to fix it by scraping off the AR coating with a polishing cloth or something.

I’m leaving mine as-is because it’s the only time I’ve seen this type of AR coating and its uniqueness makes it useful. The coating has sort of a rainbow hue depending on the angle. When I remove the lens, the beam looks white instead of green.

Ordered a green B35AM R9080 3500K w/amber switch back light. Could not resist after that vid.

DM11 > D1S :cowboy_hat_face:

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.

LuxWad - That was a great video btw! Wow, love the super clarity in the macro shots, plus the smooth motion. Just amazing!!

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

Thanks for the video! I was trying to hold off but you’ve forced my hand. Ordered one with B35AM 3500K :smiley:

It may have something to do with the individual hand-tuning the optic requires to sit at the correct height for the B35AM.

It’s a boost driver that is more expensive.

Pray tell me which competitor is selling those cheap boost driver lights, asking for a friend :smiley:

Since video shows non calibrated thermal runtime, would you mind showing properly set themp settings runtime and output?

500lm seems to me too weak for this massive heatsink of flashlight...

It’s a 98 CRI LED, it is going to get relatively hot. I guess it’s going to fare better under a cold night out than in a lumen tube.

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?

4A seems to be the absolute maximum on Eurekatronix’s high perf MCPCBs, 3.6A drive current sounds adequate to me.

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
