I’m guessing your E07 uses Anduril and your ROT66 uses NarsilM. You might want to check this.
Is it an old ROT66 before the AUX LED's in the head? If so, might be NarsilM. Once the AUX LED's were added, they went to Anduril, I believe.
No, I have 2 with Aux LED’s and NarsilM
I think you are right…It’s running NarsilM. I have aux leds in mine.
What made me post about it is that my E07 is much brighter than my ROT66. I have HG2 in the ROT66 and 40T for the E07.
A 40T pulls about 20-24 amps in the E07 with SST-20 4000K's. The HG2 probably can't compete with that, and depends on the LED's you have in the ROT66.
Forgot to mention…both have the same XP-L HI 5000k.
Does anybody know which version of Anduril the SST-20 versions use? Is it the reduced current 219 version or the full current one?
Somebody take a look and tell me if I’m dreaming or if the 219B version really is in stock again:
I also see the Nichias listed for the E07, but not the PL47.
I noticed that as well. If the copper E07 has all the QC issues worked out I may have to pick one up. :+1:
I know this is an old question, but it should use the standard version for 14 x 7135 chips.
If you’re asking about the version for the D4 and D4S with 219C emitters that reduces the FET channel output to a maximum of 80%, my understanding is no, neither version of Anduril for the ROT66 does this.

I tried to order a N219B ROT66 way back in January but after 6 weeks just cancelled my order.
I already ordered one last night right before bed at the new discounted price! That’s an amazing deal! 
You guys are discontinuing the ROT66?
Are you discontinuing it for an improved version ?
For something new ? 
ROT66 will get minor changes for next batch, model number should stay the same
Battery carrier gets changed to battery tube plus contact ring like Q8 or SP36
Does Fireflies have a new batch of 219B to use in the ROT and other lights or are we still just getting the dregs of the original batch?
I think it’s a new batch.
I think the original batch were the 98CRI versions and the second wave are 95CRI versions.
if you check their website they indicate the specifics of the 219Bs they have now
