Emisar D4S review

I am going to drop fireflies rot66 and pick up a few more d4s… what do you guys think about nichia 219ct 5000k and xp-g2 4885k ?

Purchased from Mtn.Electronics, no glue, very clean…

Green, MTN…not glued

No one knows ???
I ask a question twice and do not get a response

One strange behavior I noticed. When I set mine for stepped ramp with 10 levels and exclude the turbo with 5 clicks in the ceiling ramp config, the light cycles immediately from top to bottom mode and doesn’t stop at the top. I feel it would be more consistent for it to stop at the max just like with turbo on the unlimited ramp.

However, if I click 10 times to limit the ceiling it does this, but the max step is much closer to turbo than with 5 clicks. Works well with 20 clicks as well with the ramp max being at a more suitable level.

Also it would be handy if you could exclude the turbo from the stepped ramp max by just one click. So the ramp config would be aware that you’re in the stepped ramp mode and adapt to the currently selected mode count.

I believe 45,000cd - 450m was stated somewhere

Fourth dont be lazy and go to to intl-outdoor.com and look it up yourself.

Мог-бы так же не кричать. Вроде земляки

Thank you, but there I did not find

The maximum is 70 C. If the user enters anything above that, it’ll just save a value of 70.

On this light, I personally like XP-L HI ~5000K the best, and XP-G2 3D (~4885K) as a close second. Nichia is nice, but I just haven’t been as happy with the 219c as I was with the older 219b. The 219b emitter is probably the main thing which makes the ROT66 interesting. It doesn’t make as many lumens per emitter, but it makes really nice-looking lumens.

It looks like you found a bug. I tried a bunch of different combinations and they all worked, but 1/145/10 fails as you described. I’ll have to investigate that soon. Probably just a quirk of how the integer math works out, but it’s still quite odd.

If I understand correctly, you want it to let you choose the floor level and the number of steps, and then it would place the ceiling automatically one step below turbo?

Not quite.

I have 10 levels set for stepped ramp. I go to the ramp ceiling config and click once. This should give me to moon + 9 + turbo, where the turbo has to be double clicked. Similar with floor. I click twice in the config and I get moon + 8 modes with the lowest two discarded. So if I limit the ramp, I also get less modes, but I always know how many.

Valera, my D4S should be here in the next couple of hours, I will try to get a meter reading on lux/throw as soon as I get it.
I didn’t read my copper build because it has the new Samsung emitters, these are not factory available so the result would be irrelevant compared to the lights everyone is currently receiving. But with the Samsungs, beam distance is not very good out in the wide open, 100m and it’s difficult to make out objects like a young black calf separated from his mom. I’m sure the XP-L HI would show a different result, but this Ledil Angie optic is new to me so I don’t have experience with how it performs over different emitters.

Edit: Hank does state lumens and candela on his Intl-Outdoor site…

OTF lumen output and candela at start-up

XP-G2 S4 : 3300lm / 40,000cd

Nichia 219C : 3000lm / 20,000cd

XP-L HI : 4300lm / 45,000cd

40,000cd would reach 400M, 20,000cd would reach 282.84M and 45,000cd would reach 424.26M (according to the math) [square root of the candela x 4]

Nice photo Shirnask, really brilliant looking work on that set-up isn’t it? :smiley:

Thank you so much

Absolutely, but it tempts me to spend more money :person_facepalming:

Thanks… i will probably go with xpl 5000k or xpg2 3d.

Just ordered a black and green d4s for friends and family…

The throw on this D4S XP-L 5000 is great!
Got me wondering what the 6500 will do, it’s on its way, due Tuesday.
