Review on 🕯️ Firefly Kosher Lamp Oil Fuel - Safe, Green, Non-Toxic & Biodegradable - Virtually Odorless Paraffin Alternative for Indoor/Outdoor Use - Ideal for Lamps, Lanterns, Candles, and Tiki Torches - 5 Gallons (Bulk) by Jessica Lopez

So yeah, it's anything but "virtually odorless" unless you have a serious sinus infection. It must have a strong smell. So much so that my wife came in from the next room to ask me what the change was. After using this in a small table lamp for about 5 minutes, so much smoke came out that it set off a fire alarm in the room it was in. Note: This was on a brand new lamp that has never had any other chemicals/oils in it. Well I would strongly recommend NOT using this stuff indoors unless you like weird little things and enjoy the shrill sound of a fire alarm. I think it's nice outside.
