I think having one around is good for reference purposes. I bought a 7.2v Xenon UltraFire WF-502B (and an extra 3.7v Xenon drop-in) ten or more years ago and I still keep it just in case I want to see what 100 CRI looks like.
Pretty useless as a torch with a small hotspot with not much spill, and being too demanding on low drain cells.
I still have a Streamlight Stinger from 2007? Maybe sooner. It was my first ‘serious’ flashlight and was as bright as a 4D Mag and a lot smaller. Really popular with police officers. It still works awesome, just need to get new battery packs.
Tiger brand and Aoki flashlight featuring their younger brother, Lumintop EDC05 
I have two Victorian oil lamps, one is modern (late 1990’s), the other belonged to my Great Grandmother and dates back to the early 20th century (still works).
i already mentioned inc. lights, but forgot about my hid navy battle lantern conversion, do not use it much either, just sits on a shelf,
Hi, I'm new here. I have two 2d maglites, one 6d maglite, three 2aa mini mags, one 3aaa mini mag and a solitaire. I also have a 2d rayovac industrial and a 4aa something. All are incans.
I still have six incan flashlights and two Coleman propane lanterns.
One 3D Mag 85.
One 2cC Mag ROP
One old Rayovac from the 30s with a magnum star 5cell bulb and 6aa nimh cells
One old eveready (?) 3D “miner’s” light running a halogen bulb on 6aa nimh.
One Surefire e2e stock because the beam is fantastic.
Lastly, a Maglite Solitaire so I don’t forget how it used to be…
I still use them all; probably the ROP the most, because with the lop FM reflector, the beam is perfect.
Two 2 x AA Mini Maglight and one 2 xAA inspection light.
I have two 3D maglights. Worthless.
I have a bunch of 2AA maglights. Worthless.
I have two AAA maglights, solitaire or whatever. These were worthless even before the LED was ever invented .
Times have changed, do we want to live in the past or the future? Although, I have no intention of ever going to Mars.
Still got a coupla hotwire P60s. In a pinch, they’ll work right through another Carrington Event if need be.
Being a pedant, my lights are NiMh and Li-ion powered 
But yes, P60 xenon drop-in in a Solarforce L1T host is quite nice, something quite satisfying about the beam, it’s also handy for informal comparisons to lower CCT LEDs.
I have a bunch of MagLites that sit empty in a closet. Never could bring myself to upgrade them because it costs more than a new Led light. Might keep the largest in the car for a thumper.
Are there incand. Lights with driver and mode level on the market?
I have given up on them… retired my last Mag this spring after I dropped it and the bulb popped and the spare in the tailcap had already been used. I would like 1 P60 incan, but have never picked one up.
Someone gave me a Maglite Solitaire. It’s a nice looking blue tube, but a pathetic excuse for a light. I’d be better off with a box of matches I think. It’s on a spare keychain until I decide what keychain light I want to get.
Yes indeed. I carried by Firefoxes FF5 HID last night. It’s a beast and doesn’t overheat even on full blast. Wish I could say the same about my nutburner pocket LEDs
I’ve got a fancy old Philips incandescent bulb in my bedside lamp which has some sort of coating that transforms the already lovely ~2000K incan lighting into a very tasty rose tinted warm glow. I will miss it when it no longer illuminates my boudoir.
...still own any non-led.... No. No incans for me. The transition from sub-junk incans to real performance led lights is one of the very few modern events that I am happy about.
...still not yet own any non led... Yes. No lep, hid, etc, for me, yet. I do not want to accidentally cause problem for anyone far away, and I like to rapid cycle on/off on certain occasions.
Yes I still have a bunch of incans including a Streamlite TL3, Tekna Splashlite (still a nice light in my opinion), and the notorious USL of much CPF drama. (I also have the older LED version of the Spashlite). I don’t know if my USL still works. I haven’t used any of these in ages, but I used to carry the Splashlite once in a while, so I might do it again soon just because. The rest, meh, I guess I can give them away to thankful takers if there is a power failure here.
I still have an incandescent Surefire P60 I keep as a CRI reference. No LEPs this far, I’m more of a floody urban EDC kind of guy.
