If you could post your favorite lights with that favorite emitter, that’d be cool too! Smile

I’m loving my D4V2s with the 2700k e21a. I got one in 4500k and the tint is just weird to me. I haven’t really made up my mind about the 4500k yet—not sure if I like it.

I’m kind of disappointed with my D4V2 with 4500k E21. Color seems really neutral but output seems weaker than my FWAA 4000k. I was EDCing it but went back to my SP31. Can’t really comment on the other E21s

Does your FWAA also have Nichia e21a emitters? I’m not familiar with that light. There might be different bins of the e21a that could account for the difference. The D4V2 with e21a emitters is supposed to max out at 1200 lumens.

When I get home I’m going to test it against my SC64C LE for as baseline. I trust the output rating of 828 lumens on that—the E21a 4500k D4V2 should be brighter.

I do agree that it somehow seems underwhelming. To me, the beam looks almost purple. On the other hand, I never thought my SP36 BLF looked green, but now that I compare that to the E21a in 4500k it looks HELLA green haha

My go-to light is a KR4 mule with a combination of 3500k and 4500k E21a emitters. It puts out a neutral, warmish pool of light that is ample to see by; the 3/150 moonlight is perfect for night-time reading. During the summer, I have been using it with a 18350 tube.

Most temps should be around 3500 to 4500. I don’t see the advantage of these over 219b.

I like a 2700/4500 combo. Brings the duv down a bit and feels warm enough without going overboard. Great for cooking, indoor, general close range stuff. CRI still super high without mixing in the 2200 or 2000 versions (which I like as a bedside table light).

2000k high CRI is very unique so I think that’s the winner of the bunch. 2200k red is too low. SST20 JA3 bin 2700k is better than the E21A, 3500k is nice and rosy. There are more throwy and efficient options over 3500k.

Folomov C2, 3000K. The light is full of flaws (high standby drain, exotic battery, moon followed by memorized level instead of low), but the beam color is very nice.

Well said..

And the light with 2000k that’s my favorite is a Skilhunt H03 running Anduril.

I see a lot of people prefer 2700k…

I thought as being incan lover i’m the kind of people that will extinct since incans are 3000-4000k range and showing accuratley colors at these temperatures but i guess i was wrong.

When you need to see colors in real life as they are then 5000K (represents Sun at 3 o’clock afternnon) and 5700K (Sun at high noon) will be the true one. Anything warmer is just…for fun.

I prefer 2700K-3000K for dim evening lighting. Usually I’m trying to be around 4000K, I like it best. I also like 5000K and have pretty decent 219c, 144a, 351D, e21a in this temperature.

I like the 2700k because it reminds me of a sunset. I also like it because it is really easy on the eyes. My use-case for 2700k is the nightstand where it won’t blast me back into full consciousness if I have to use it at night or just before bed. Light that mimics sunlight tells the brain to stop producing melatonin, the hormone that helps regulate sleep. So no, not just for fun.

Light that mimics sunset…

Dear god… R9 numbers tells your brain that is “sunset”.

Color doesn’t, it’s just romantic.

LOOOOOL

Congratulations, you just made the most unpleasant post I’ve ever seen on BLF. This is the kind of behavior I left the cesspool Reddit to avoid. You could have simply posted some helpful information about R9 values but no, you mock and laugh derisively instead.

Not to mention you put words in my mouth. I said that the 2700k e21a emitter in particular reminded me of sunset.

Sorry i sounded like that. English is not my first language.

But all of you jumping on these low temps should have educate your self or at least ask what’s with those 2k colors. 
Only useful for a nightstand light or to navigate your house before going to bed (for that reason i use deep red 660nm light).

For real work it’s terrible

In your country, a criticism of someone’s knowledge followed by laughter is not considered rude? SUSpicious

Anyway, I still think the 2700k e21a emitter is good for nighttime use. Of course a pure red light would be better, but as you pointed out pure red sucks for anything else. The 2700k e21a is a pleasant compromise in my opinion.

High-CRI 5700k are quite underrated. The LH351D and 219C Convoy S2+ at 5700k are both excellent for “midday like” illumination.

Just anecdotal but below 3000k gets odd for me in real use. I loved my 2700k Samsung lh351 TIL I got in a cave with it. Something about the color temp made the walls more difficult to navigate.

Warm tints are comforting at home but I would experiment before I put a lot of stock in them.

At home is where I plan to use mine. I’d think that 4000k would be nice for caving but I base this on a gut feeling and NO experience in caves.

Application is everything. Yeah, the old carbide lamps were probably more neutral than 2700k. Oil lamps? Maybe that or lower. For caving I’d go with 3500~4500k.

I have one 3000k emitter, an older 219B in my TH20. The driver doesn’t push it so it’s a bit of a weak output. But terrific for hands-free illumination of close range tasks. When going outside at night to push trash & recyclables to the curb, it’s an ideal choice.

With dark adapted eyes I find absolutely zero need to exceed 4800-5000K cct. I also agree that dipping below 3300K really starts losing visibility fast for active tasks. My pattern these days is CW/low CRI is strictly for throwers (Osrams mostly), my EDC is between 3900 and 4500 (favorite is 3500+4500 mix e17a) but typically is SST20 4K. I find a 2700+4000 sst20 mix a great house light mix. I have a 3000K sst20 in a p60 that I keep around just because, though it’s never used. But a light that gets used every night is my beloved 2000k e17a quad H03.

What do you mean by “more neutral”? Carbide lamps run at near 2200K. Oil lamps cover a fairly broad range of CCT from 1900K flat wick lamps to 2700K incandescent mantle lights.
