Convoy S2+ Luminus SST20 vs Nichia 219c beam profile question

No, straight drop in.

Of course, it’s: TIR—- Glass lens.

Remove the glass, remove the reflector, put in the lens, put in the lens, and you’ve got a “new” light.

-The size of the led die is very important in determining flood/throw.
The SST20 is tiny compared to the XML2 that is why it produces more throw in the same reflector.

-A de-domed led increases the light angle, so more of the emitted light will hit the reflector and become throw.

BlueSwordM, Thanks for this information :smiley:

Johm, I do understand what you mean now. I incorrectly assumed that the shape of the dome contributed to the flood but yes the SST20 die is tiny. Thanks for pointing this out!

On another note, I see in Convoy’s store Simon now sells a C8+ but with SST40. When I look at the SST40 from google images, it appears this die looks large like XML2 (not small like XPL-Hi or SST20)

Can we hope for a tight and far throw with C8+ SMO and SST40? I have C8 with XML2 and the throw was not so great, but my C8 with XPL-HI produces great throw.

The beam will be tighter with the XPL-HI.

However the SST-40 produces twice as many lumens so the throw should be similar but bigger hotspot.

Hi, do you have comparison between SST20 and Nichia 219C? Photos, or which one is more neutral white.

That all depends of the tint and bin of the led.
What are you looking for?

Personally, i prefer the 5000K 219C over the SST20

SST20 and Nichia 4000K
Hmm I was looking at this 5000K too, but found it too blue, from the photos. Is it really noticable blue?

No, but I prefer the SST-20 4000k anyway since it throws quite a bit farther than the 219C, and has better red color rendition.

And that’s the point, I am looking for indoor use light, more flood, in camping, 10m max distance, in tent, reading and so on.
I have one XML2 and it looks little rosy, 3D in ANSI. Would rather have 3C, don’t like this red colour. But I guess Nichia 4000K nad SST20 looks little rosy, right?

Both the Nichia 219c 4000k i have are more warmish yellow in tint

@Mocarny, for floody use, get a 60 degree lens.

You’ll see the difference in flood. :slight_smile:

Right, I will get this lens for sure :slight_smile:

But I am looking for the purest of the pure white, the one and only. It can be 80+ CRI, no need to have 90+ CRI

Try the Olight H2R or H1, these are ridiculously neutral.

Otherwise a quad 4500K+5000K E21A mix should be very neutral I suspect.

Hmm I can’t get quad, planning to put this LED in S2+ to have small, low power camping light. I am so close to get this Nichia 219C 5000K, but I’m afraid it is little bluish. Maybe I should buy both 4000K and 5000K and find this out myself. And SST20 :slight_smile:

Quad E21A has rougly the size of a “normal” led so it fit’s in the S2+ with a 45 o 60dg TIR.
5000K 219C is imo terrible for woodland, it’s coldish and does a bad job at rendering greens and browns, 4000K or even less does this better.

I have the 4000k 219c and the 4000k SST20. The 219c has a bigger and more yellow hotspot. The SST20 is tighter, throws farther and is a little greenish at lower levels. I put DC-Fix on the 219 and it is great now. Great for outdoors, a little more floody and a little less yellow in the center. Decent for short to medium long distance around a campsite and trail.

I plan on getting a filter for the sst20 to lessen the green at the lower levels. I know it will affect the throw some but I think it will be worth it. I hardly noticed the green when I first got it. But when I compared it to some of my other lights, it stood out to me. It’s fixable though. I basically use my lights at 300 lumens or less. Generally around a 100.

I like your last suggestion on getting several different ones and compare. Find what’s right for you. You can keep the others or sell or give away. It won’t break the bank and you will know what you like.

Is the 219C greenish at the low levels? And…what is DC-Fix? :stuck_out_tongue:

No green on mine. Dc-Fix is a window film you can get at many hardware stores to diffuse light. You can get a big roll for not much money or you can get a smaller sheet from a member here for less money. There are many styles. I have it on a few lights to tweak them to my liking. Google it to get a lot more information.

Wow, this DC-Fix looks great!

Anyone knows the CRI R9 value of the 219C 4000K?

Have you got this model number correct?
I cant find any information about this particular LED at all.
