Condensation in ground spotlights

Ground spotlights for pathways, façades or stages must function reliably even under changing weather conditions. However, large temperature differences between operation and cooling phase frequently cause condensation inside the housing – a problem that can lead to corrosion, short circuits or clouding of the light surfaces in the long term.

Challenge: moisture in ground-level luminaire housings

When the luminaire is switched off, the housing cools down and negative pressure is created. This draws in moist ambient air via seals or micro-cracks, which then condenses on the cold interior surfaces. Even with high-quality, IP-protected luminaires, this effect can hardly be avoided over time, especially with frequent temperature changes outdoors. The consequences range from fogged light surfaces and electrical failures to shortened luminaire service life.

Solution: Use of BoxDryy® high-performance desiccant

To reliably prevent condensation, ThoMar recommends the use of a salt-starch-based high-performance desiccant such as BoxDryy®. It is placed directly inside the luminaire housing and binds the moisture drawn in during cooling before it can condense. Installation is straightforward, can also be carried out retrospectively and can be easily integrated into existing maintenance routines.

Result: Protection against moisture damage and longer luminaire service life

BoxDryy® prevents condensation formation in the housing, protects electronic components from corrosion and permanently maintains light output. For manufacturers, this means: higher product safety, fewer complaints and a longer service life for the luminaires – even under demanding environmental conditions.
