Bulb breakage is not an issue:
- my lamps died without breakage so far
- little, if any, free metal vapour inside the bulb, as it re-deposits on the filament (hence halogen lamps are longer life ones)
So, the main problems with this
mod are:
- energy inefficiency (=> to be powered from USB port)
- liquid inefficiency (=> more vapour, more liquid consumed)
- heat up time (=> to be continuously swithed on while smoking)
