Can I ask why it will produce terrible color rendering? In addition to commercial scanners that used narrowband trichromatic (RGB) light sources, hobbyists are creating their own RGB light sources to digitize color negative film claiming superior results and putting forward arguments why this is better:
(NB: Most film I shoot is slide film, which I’ve been told doesn’t benefit from RGB light sources because it’s intended viewing was projected with a broad-spectrum white light [likely a warmer than daylight (but color temperature isn’t much of a concern for digitizing slides)] so I haven’t dug into this much.)
RGB should be fine, especially if you use a genuine ultra-high CRI source. A few companies make them, I think Waveform is one of the more well-known. If you really want to spend money, the optics suppliers like ThorLabs sell broadband LED sources. In an ideal world you could calibrate the image sensor against a known spectrum so you'd know its response. If you can estimate colour to a reasonable degree then you can transform it to what it "should" look like. Nevermind that pixels are single-wavelength as well.
Negative Supply use something similar in their light tables, though I don't know exactly what the source or spectrum is. They're highly regarded enough that I think it's not an issue.
You can also use LEDs for enlarging, but you need to be careful about buying the right bands for the paper. I've used Luxeon SunPlus with some success as you can buy the correct green/blue for the different contrast layers. Though for B&W, even a random 5500K module from Cree worked quite well.
I got one of these from the latest batch last week and I’m not entirely convinced by it yet. I need to experiment some more but I went back and did a couple rolls from this summer and so far I think the cslite warm setting + negative lab pro results are better and more consistent. I’m still getting some wonky colour casts with it. It’s nice that the control app lets you change the power of each LED colour separately, so that’s the next thing I’m going to experiment with.
I’ll also note that negative lab pro hates negatives that are scanned with it. They don’t turn out at all. If you’re using it, you should expect to be inverting them manually, which is kind of a pain. I was quietly hoping (but not expecting) to still see some of the benefits of it when passing them through NLP.
But also export your config because you will inevitably forget to screenshot a thing or seven and you can poke around the config export for that port number or IP address.
Worst case scenario, you can spin up a VM of pfsense quickly and reimport the config if you have to.
I have off-box backups of my configs. Thanks for the VM idea; sometimes I forget to use VMs to do things "embedded" devices usually do for me; switches, routers, etc!
There's going to be a point soon where I have two fiber providers (and thus two WAN links) for a little while, I'll try move the existing pfSense off of my Protectli box to a VM, keep everything up for the family while I configure OPNSense on the Protectli, then if I do it right, I can move everything over with minimal reconfiguration.

Mine mnemonic is use e.g. when you could say “for eg-zample” and use i.e. when you could say “that is” — ie to is. Admittedly, the second half isn’t as good as the first. : )
