I finally built a tint-mixed triple in a Convoy S6 host that I have wanted for some time. I had the parts from RMM lying around for nearly a year!
I love the resultant beam tint - to me, seems very pure neutral white. I don’t have CRI measuring equipment, but the tint-mixed, wider spectrum light does seem to result in impressive color rendering- at least to my eyes. I realize I could be fooled into thinking the CRI of the mixed tint system has improved relative to same-tint LEDs. However, I also have a hard time telling the beam difference between the triple tint mixed S6 build and a triple Nichia 219B 90+ CRI I have built in the past using an S2 host.
In the mixed tint S6 build, I chose the following LEDs, available at the time of order:
- XP-G2 Q2 7C4 (90+ CRI)
- XP-G2 R5 3C
- XP-G2 S2 1D
The combined mixed-tint using the above LEDs results in a target mixed tint of about 5000K. The resultant tint calculation for the 3 mixed LEDs was determined by using the approach described by ToyKeeper in Post #2193 of the following link:
I used RMM’s FET + 7135 Driver (MTN17DD) flashed with (then) standard firmware with turbo timer of 120 seconds. Also used in this build is RMM’s Copper Spacer for the S2/S6. I bypassed the springs on both the clicky switch and on the driver. For some reason, I could not extract the switch from the S6 tailcap. The retaining ring seemed to be stripped in place out of the box. I luckily had a spare S3 host lying around from a previous build and was able to use the already-spring-bypassed S3 tailcap on the S6.
Presently, this is my favorite EDC torch. It has great tint and really good modes.
I now have parts on order to build a tint-mixed triple using the short 18350 version of the S2+ host with associated copper spacer. I’ll be using an updated 17mm Driver available via RMM (MTN17DDm-NUV) flashed with Toykeeper’s BLF A6 firmware using a 30 sec turbo timer. The LEDs I have on order that were available to target a resultant ~5000K beam are:
XP-L HI U3 3000K 80+ CRI
XP-L HI V2 1A
XP-L HI V2 3D
I’m really looking forward to this S2+ triple tint mix build as a more compact, lighter version of the above tint-mixed S6 triple. I realize this will heat up pretty fast and drain an 18350 quickly in turbo mode, but I don’t expect to use Turbo mode except for short bursts.
