Am breathing nichia!

Are b's no longer made

I'm not sure, but it's a pity if they aren't. I like them much better than the c's. Their downside is poor efficiency, but people going for that pure high CRI tint don't really care about efficiency anyway.

Interesting

I honestly don't think the efficiency of the c is even a concern compared to the b. You really aren't going to gain enough. I also prefer the b over c and will take it anyday over the c. Runtime isn't greatly increased with c imo.

Are b's no longer made

As far as i know they are still available, just not from hds. I have many 219b from malkoff (illumn) and pretty sure still available.

I am not sure if nichia still actually makes them and not sure which brand still uses them. Seems like most brands use nichia c, possibly because they can claim higher efficiency even though i feel that's a moot point

I dont think they are still made, but there is of course some available out there. I too prefer the b overall to the c , the 319a is not too bad but again 219b my preference. There is a 219d but cant comment to having not owned any samples.

 

[WalkIntoTheLight]

219a is also very nice. I can't really tell the difference between a and b. I doubt anyone still sells the 219a.

Yes, i have the 219a in my very 1st v54 light, olight m20 single mode.

I am sure around or close to 4k, yes hard to tell the difference to my eyes with the 9080 and 9050 4k. I like them all very much!

Rule of thumb, 219b is 30% more efficient than 219a (and 219c is 30% more than 219b)

example, 219b (middle) is 36% brighter than 219a (left):

Left: Niteye Eye10 TiC Titanium rotary w triple N219a 4500k 9050 makes 306 lumens
Middle: Jetbeam TCR-1 Titanium rotary, converted to N219b 4500k 9080 makes 415 lumens
Right: Niteye Eye10 with the stock 6000k XM-L makes 635 lumens
(the N219b is 35% less bright than the XM-L)

photo illustrates beam color, these lights are not on at Maximum brightness:

Next photo illustrates beam color of 219b 3500k 9080. It makes 350 lumens. (16% less than 219b 4500k 9080):

All the N219 LEDs are modifications, not stock.

I want to breath nichia with @nichia!

whose selling a 219b light nowadays?

Nichia219b for ever


Check the malkoff MDC 16650 flashlight with nichia 219b R50 on illumn

 

[INFRNL]

Excellent choice but a warning should be given to those that can't handle pwm

Another option is to find some 219b emitters and have them swapped into a light of your choice

I really like my malkoff mdc 219b

 

[Nichia!]

I bought 2 of them but they are still @ my forward

 

[trailhunter]

Would a single 219b emitter work good in a 26650 light?

 

[Nichia!]

I have been thinking about 26650 battery p60 host and nichia 219b dropin for months now..

But I want triple or Quad dropin and must be Really Bright and with Secondary red led..

How would 26650 with a triple or quad host pan out in terms of power and runtime?

 

[trailhunter]

Going to work with chris to see if he can build a triple nichia 219b 4500k in a v3 copper/brass v3 dragon

Would a single 219b emitter work good in a 26650 light?

Of course it would work well, but it would depend on the driver used. For example the 219B isnt a big fan of being put behind a FET driver especially with a high drain cell. The same can be said for the 219C but it is more resilient. With that you should use a current limiting driver and thus you can calculate the aprox runtime based upon the mode and the current draw associated with that mode and then compare it to the capacity of the 26650.

To answer your question after it, It also depends on the driver used, the mode used, the cell used and the number of emitters.

Looks more green on right

Correct, the green one is the 219B

I haven't much time with them yet but i don't see the red like sw45 has.

From my limited use so far sw35, sw40 are great without the purple i see in the sw45.

I will try to get a better idea of the differences tonight.

Are you sure you are using the SW45 and not the SW45k? The SW45k is the one known to be purple.

 

[INFRNL]

That's a good? They are what hds has offered, i don't recall the exact details. I'd have to look into it.

I currently just know they are sw45 219b 4500k r9080 same goes for the sw35/sw40 i have. I know the 9080 has more red than r9050 other than that, I'm not an emitter expert

Some may already know the answer but I'll check into it

In that case I know the answer is the SW45k as it is what I ordered as well. These are a special run of emitters meant to be on the rosy side.
