Made in The UK, (original Poole factory complex).
High quality glass bottles, properly made electrical connections, polished chrome metal fittings, rich vibrant long lasting colours, great service from Mathmos, spares available (ever dented a cap top)? ..& proven long lasting product.
I put my Mathmos collection through "consumer hell" & they come up trumps time & time again, spares & support on the other end of a uk phoneline, well designed, stable of lava lamps!
This one, amongst others is about as iconic as it gets, when you see a lava lamp on a tv set it's invariably a mathmos, not some no-name dubious knock off, why? they're instantly recogniseable, & work for decades.
This model slots together so easily (the fins) & is stable enough for me to have had it in my daughters room since she was 4, prior to that it was a jet version as they're even safer in terms of stability.
Interchangeable oil / wax colour bottles, so change as you change your decor if you so wish, these bottles are from the smaller range "Astro-baby" ..so any you fancy from that range will fit in this model, interchangeable nature of the bottles has stood Mathmos in good stead throughout it's long life.
The glass bottles are tough, I've never managed to break one yet (thank god)
For the energy conscious (me too) these take a 25 watt screw in bulb so make fdr a pretty low wattage nightlight or decoration.
A really cold room will slow the wax but typically expect some movement within 40 minutes or so.
I leave mine on all night & it's fine! (just in case you were wondering) ...as good as the day it was bought in terms of colour, vibrancy etc (no decay).
Do keep them out of harsh sunlight which WILL GRADUALLY make the wax colour fade, but such is the high quality of mathmos it will take some doing & even them will look better than a cheapo version.
Enjoy!
