I've had my Aladdin lamp since 1988 and use it regularly (except in the summer - puts out too dang much heat!). I burn only K1 kerosene and it is completely odorless except for a quick whiff when you start it and when you extinguish it. They really are awesome!
For a good LED flashlight, I've been really happy with these:
Rayovac 2AA LED. They are $15 at Home Depot and they are really bright. The other nice thing is it will drain the batteries down to around 1.1V per cell before it quits, while maintaining consistent brightness. Some other lights I've had get flaky below 1.2V or even higher.
You can also still buy gaslights from several places, my favorite being Lehman's:
Lehman's gas lightsI still take one of several of my Coleman white gas lanterns on camping trips and my 413G stove puts out way more heat than any propane stove I've tried. I can't make the switch to LED lanterns. The ritual, the glow, and the gentle hiss from the Coleman just defines camping.
