Too far away CCT mixes can and usually will screw up the CRI, although it may not matter much (if at all) depending on user preferences. To avoid too much CRI loss I get along with a maximum of 1 to 1.5K CCT distance when mixing high CRI emitter dyads. Some testing in this regard would be nice to see (CCT emitter delta vs CRI loss), but we need to convince some tester about this. maukka has a nice deal of high CRI emitters… O:)
It’s probably normal but as I am now working with the springs, I noticed that the small spring (from the previous gb of course) remains shorter when compressed the first time?
Yes, with these springs, both small and large, it is normal for it to stay somewhat compressed permanently from the first use. The new ones will be the same too. It shouldn’t get any worse though. Once that little bit of length is lost the first time, that should be all.
Yeah, it’s more of a problem with the smaller spring compared to the larger one, because the wire thickness/spring diameter ratio is lower than the big spring, meaning more room for deformation.
Therefore, it will deform it more compared to the large spring in terms of %.
The small springs I've used in a coupe of lights are pretty stiff, stiffer than most stock springs. Maybe good for some mods, and for others may make it harder to thread on a tailcap - I'm having some of that trouble on a couple mods. Was debating cutting the spring down, but getting it all flat may be a challenge for me. Shame because I've decided against using them in some lights. I'd assume if I try cutting then grinding flat, I'd be taking off a fair amount of the conductive coating, or is the full spring conductive to the core?
