Another aspect to consider is possible damage to the glass tubes due to external influences. For example, if a single glass element (system) gradually loses luminosity, the reason may be, in addition to the electrical accessories (as described above), a break or crack in the glass through which gas escapes. Do not worry, this is not harmful to people, but the hairline cracks can be so fine that they are not visible to the naked eye.
Damage to the glass tube cannot be repaired, so the affected element must be reproduced and replaced. If your neon is behaving abnormally – e.g. flickering or visibly reduced brightness – and no clear defects are detectable, please contact our support team for further action.
Over time, the gas content of the neon tube may decrease due to physical processes. Theoretically, it is possible to refill the gas. However, since this is a logistically and financially very costly undertaking, it is usually more efficient to replace the glass element in question.
