I'm on my 3rd Mathmos bulb for my heritage lamp. The first lasted about a month, the second lasted 5 months. If the third blows in short space of time, I think I'll just get something cheaper. You can apparently get a pack of 10 from AMAzon for the same price as 1 from Mathmos!
Thank you! Such a kooky and wonderful website. Glad I stumbled onto it. The new teal wax lamp is certainly gorgeous. Water still a bit cloudy, but will run my lamp for a few days and see what happens. Really nice flow. After reading about changing the liquid, I'm getting excited to try one myself. Will have to learn more about the Goo Kit (?) Anyway, cheers!
