Necrothreading my own but it's been a few years.... tech in lighting has improved and more importantly, battery tech has improved!
I'm thinking, with a nice, easy replace, lithium pack, in a large enough base..... +3000 lm properly defused at 35w(ish), no cooling concerns unlike LED, can be fairly color friendly, more durable (ime) since electronics are sealed and bulb is relatively inert, more lumens than a gas lantern, less sensitive then LED......
I still think there may be a place for these.
Albeit not for universal usage (no real dimming, has warm up time & cool down time) but maybe as the "main" usage for dinner time or pasture walking.
