The fact that LED lamps contain no filaments actually makes them more resistant to vibrations and impact than traditional metal halide lamps. This is a crucial consideration for the construction and mining industries, which naturally demand that its equipment must be durable enough to survive harsh working conditions. But, it is not only the bulbs themselves that must be robust; the housing must be tough too. Look for LED lamps that are contained in shock-proof housing and offer ingress protection against dirt and other particles. Transportation is another factor to consider, since this is typically when breakages can occur. It is not just the LED lamp itself, but the whole unit that must fold down into a compact form that is capable of withstanding the pressures of being moved across and between sites.
