For vulnerable areas such as stairwells, toilet blocks and public buildings where vandalism is a problem, a robust lighting solution is required. Our Holt Die-Cast Bulkhead model is manufactured from a die-cast aluminium base and secured with stainless steel anti-tamper screws to deter and hinder vandals.


The diffuser is designed from a high-grade polycarbonate material to maximise the LOR (Light Output Ratio) for premium illumination in high-security areas. Presence detection options make this model even more suited for problematic spaces as the light model can be adjusted to come on instantly after sensing movement to deter individuals.
