Sorry, I think I got confused with the list # between this light and a different group buy. I’m not sure what number I’m on the list and if there even is a list for this.
I wouldn’t trust a light using an e-switch for a WML light that wasn’t designed specifically for it, especially on a rifle or shotgun. Any loss of contact means the light shuts off and in the case of Anduril will leave any “momentary” modes, etc.
This comparison vid has some options that are pretty throwy:
Cloud Defensive and Modlite are spendy, but not overpriced for what you get.
Weltool and I think Maxtoch? offer some options using Osram emitters as well. Weltool shows several of their models being used for WML, dunno how they hold up under real use though.
Malkoff has some new models/heads that use White Flats and very throwy optics, not sure if they’re hitting the kind of numbers you’re looking for.
Got my shipping notification for KR1 and D4SV2, hooray! For something different I’m going to see how much productive stuff I can get done between now and NLD. Maybe I’ll read a book, build a garden, start a new routine…
Would not recommend using any performance-oriented enthusiast lights on a weapon. Performance lights are designed to minimize resistance and maximize current… but a weapon light needs to minimize shock and maximize reliability. Totally different goals.
Get something with long, sturdy springs at both ends of the battery, with a protected cell… not something like this which is sized for an unprotected cell and designed to let the spring lay flat during use.
Received my kr4 today. Really like the nonslip feel of this light. Really appreciate the quality too especially after the Meote …
Yes, there will be in the future.
E21A beamshot tint side by side please?

Great to know E21A is here but Hank I wish you got the E21A 2000K instead of the 2200k because the 2000K is 9090 whereas the 2200K is 9050. The 2000K also has less positive DUV so less yellow and the closest to natural candle light which is 1800K. The E21A 2000K also has the least blue wavelength of any LED I’ve seen and has practically no impact on your sleep/melatonin, attracts almost no insects for night time hikes and very little impact on night vision, so it serves some very specialized uses. I hope you can get some 2000K for your next order.
You can compare their parameters with Maukka’s spreadsheet.
Above link to E21 version is broken. Right one

That looks like a good overall range of color temperatures to offer.
We should be able to get other CCT’s from Clemence once shipping returns to normal. Granted, swaps aren’t for everyone. This would also likely be one of the more difficult swaps, since the the KR4 has the aux board to remove and reinstall, as well, and E21A’s are reportedly harder to reflow than typical XP-footprint emitters.
By the way, I know Clemence’s E21A’s measured better than R9080 for the 2000K, but the Nichia datasheet does not list R9080 options for either the 2000K or the 2200K. I don’t know if the 2000K consistently turn out better than specified, if Clemence got a special batch, or if it was just luck of the draw. Regardless, I would not assume 2000K are easy to get in R9080.
However both 2200K and 2000K are rated R9050, there is no R9080 that is somehow could have been an actual option.
Besides, the amount of bins Nichia offers does not make them all equal, actually quite different, like any LED there are more than one bin for a certain CCT. So one example does not mean all are the same.
Despite the E21A 2000K is rated at 9050, the batches Clemence got always measured 9080 and above. I’m thinking it is consistent. The 16 emitters mule with the 2000K would make the perfect candle light with Anduril. I bet it would look so natural, you can’t tell the difference from a real candle.
I wish, but for his last restock a few days ago they didn’t have 2000K in same the flux/color rank as before, quote from when I asked him :
Why is E21A so special?
Why shold I buy this LED?
Which version of 4 available will you buy?
If having the highest CRI is your #1 attribute then you would want this. If you value output/efficiency/beam profile above CRI then you may be better served with a different LED, just depends on use case.
Color temp is personal preference but since he has a few to choose from you could combine them to make nearly anything between 2200K and 5000K
Hi Hank, do you plan to release a KR4 tailcap with lanyard hole? Like the D4v2?
Probably not since it comes with a lanyard clip.
And there is a lanyard ring comes with the light which many customers may not even be aware of.
