mailing +25 dropins isn't too bad as long as you start with mine then mail out one a week.

It'll be tough to dedome with the LED in the reflector. It's more of a push at the base and lift up to remove the dome.
That movement will be difficult with limited working space

If we do this it’s gonna have to be half dedome and half domed or some variation of it because the majority of people I have round up will want Dedomed and if they are all domed we may not have enough guys for the GB, most people will not want to dedome theirselves or take the chances of screwing up a one of a kind module. I certainly would rather a professional dedome it while it’s not inside the reflector regardless how easy it may seem

219b 4500k is king...especially if that's from your batch of D200.

 

[thermal guy]

if I take the lead then @thermal guy isn’t getting one. Haha

No, I’ll be getting two😂😂

 

[jabe1]

M61 or M361 LMH 4500k please

 

[timbo114]

DD or NOT to DD .... that is the question.
FYI for the DIYers .... there is a glass lens UNDER the dome, protecting the chip.

dotcpf. or PSM for position of GB Master, hey even kerneldrop!.
thanks.

 

[jon_slider]

imo, DeDomed is a Bad Idea

I think if you want a Neutral Tint, you should Not Dedome
and if you want a 4500K Color Temp, you should Not DeDome
and if you want a Phat round, clean hotspot, Do NOT DeDome


If otoh, you want a Warm Orange colored LED, with a small hotspot that lacks a clean round border.. And looks Orange, not pink, DeDome is DeWay to mess up a perfectly good LED..

notice how much Warmer, 1100K lower, the CCT goes after dedoming, in addition to lowering the Tint DUV farther below the BBL

I believe 4500 dome on 519A is very nice then.
what would a de dome 5700 519A be then ? 4600k?.

 

[jon_slider]

what would a de dome 5700 519A be then

about 4000K..
they drop a LOT, partly because the 5700K are actually about 5200K

the two on the left are 5700K and 5700K DeDomed:

 

[neutralwhite]

wow , what changes de-dome can do to these. thanks John. why not just have a 219B 4500k ?. whats the difference with 519A 4500 and 219b 4500 ?. thanks again.

Is there a duv you prefer?

I take it that the Samsung 351 would most likely have a positive duv since it highlights greens and has a shade of green to it?

thanks.

I would do it and handle the financing no problem...create a Jotform to do the ordering and organizing.
The issue for me is packaging and taking it to the post office.

Now if we limited it to 13 people and required 2 dropins.....I MIGHT would do it.
Better yet.... limit it to 9 people and require 3 dropins.
Even better...limit it to 3 people and require 9 dropins.

Jon has the nice comparison photos, thanks. For me I’ve had a few lights swapped with 4500k dedomed to achieve a nice 3500k with a negative duv (more rosy, less green). I don’t want to say it’s a 219 rosy tint (I missed that era) but I’ve replaced a 219b 3500k, a 219c 4000k and a 319a 4000k and prefer the 519a in every case. I’d dial back the red tint just a bit if I could but strongly prefer it to the yellow 219c or the the other 4000k LEDs I had for outdoors at night. First time I’ve had any rosy tint with a warm hue. All 3 in orange peel reflectors.

 

[jonathannnc]

Still in for 519a 4500k DD. Anyone else in? I’m in for two. I would gladly lead if I didn’t drive all day.

Let’s be honest here @kerneldrop , the simplest solution would be limit to 1 person (you) and 25 drop ins.

 

[thermal guy]

Every time Jon makes a point as to why it’s not a good idea to DeDome the 519-A it makes me want it more😁. That warm beam is nice!

 

[jon_slider]

why not just have a 219B 4500k ?. whats the difference with 519A 4500 and 219b 4500 ?.

we have different applications, and hence different preferences

trying to get 25 people to buy the same setup is challenging. I suggest you just make up a list of each persons desired LED and dome status.. and let Andy go to town building 25 different LED stars..

instead of seeking concensus, just give everyone their personal choice.

if someguy wants a dedomed 2700K, just give the Wookie What he Wants.. lol

> Is there a duv you prefer?

Im bonded with sw45k at -0.0080 to -0.0120

> I take it that the Samsung 351 would most likely have a positive duv since it highlights greens and has a shade of green to it?

yes, about 0.0040,

and for reference, sunlight is about 0,0032

Ok, slider is the real deal. His honesty and positive intent is without question. But like so many reviewers and others, just because your emitter looks a certain way does not mean the same LED won’t be significantly different. In the case of dedoming, who knows how different methods might change results. I am guessing slider did his own dedoming. Emisar did my dedoming. It is on the right of a Banggood Convoy S2+ with the 4500K 519a:

 

[KITROBASKIN]

Furthermore, variations in emitters as well as reflectors occur, right?

Here is a comparison of the 4500K 519a on the left, and the smashingly beautiful Samsung in 5000K in THE Fraz Labs qt. (Beautiful for snow walks)
