Funny you mention that, ’cause I got a few LED lanterns from Amazon for exactly that, swapping out the craptastic Angry Blue™ LEDs with some nice 2000K LEDs scavenged from strip-lights.
No flicker, gonna use it probably with the come-with “volume control” circuit, or at least just the potentiometer from it.
I should have mentioned I’ve used beaded optics and it does look perfectly fine with them, but they aren’t as throwy as the clear ones. It seems like unless there is quite a bit of mixing, you get that huge yellow blob, so clear optics are out.
I remember you mentioning the Stanley, goggled all around trying to find somewhere to get some. Only RS in the UK had any, but shipping would’ve been obscene (and USD→UKP even worse), and Mouser or whoever was supposed to have some locally, had 0 stock and no resupply in the foreseeable future.
So I hit AX and grabbed pretty much anything that said “2000K”.
Just put the 2000K into ultrafire uf10. What a great sunset tint! Not sure it is very useful in any real world application but looks just gorgeous. It may end up in a headlamp for bedside service.
Clemence, thanks again for making these e21s available. Most of them are beyond great.
The setting on the picture is 1.5 lumen, so 1/10 the light output of a candle which is rather perfect for night use in my son’s bedroom when we stay the night somewhere else (myself I prefer no light at all at night), the runtime should be about 100 hours on a battery load.
Yes, it should get along very well with copper. And yes, this CCT is great for very low lumens so I am wondering if there is a nice twisty AAA host with a firefly mode, where the board can be installed after heavy sandung. Like, Fenix E05 form factor, but with a <~1lm lowest mode
I usually put a ping pong ball or any white milky plastic bottle on my EDC to get more of the lights directed to the table when outside (dim cafe or restaurant). And use it ceiling bounced in the room or tent.
I just played and tested a Tiny 26650 DQG for Pavlo. Saw some of the smallest EDC in George’s collection. I plan to get some for myself. Maybe I’m late at this but just amazed at how he boosted single 26650 to feed 7x XPG2 at 1A.
His smaller EDCs could be a great host for this 2000K
I have a Spy waiting for an Optisolis. Actually it is waiting for Arctic Alumina, which I will cover the central pad with to avoid grounding of the LED.
I just recalled that you installed some e21s to E05, didn’t you? Did you use your boards?
On the topic of extra-warm emitters, Digikey has some XTE 2200K emitters (80 CRI).
Just put one in a headlamp for night reading. The tint is very close to an incandescent filament bulb at a low setting and is very cozy, but on high modes it can be obnoxiously yellow/orange.
Mounting it on a DTP X-series board (noctigon) could possibly get it up to 2 amps or more. Maybe someone will put an XTE emitter to the test to see what they are really capable of
I hope more companies start producing high powered LEDs in the 2300-2500K range. I would love to have a floody caving headlamp that can mimic the tint and CRI of a carbide headlamp.
