UV LED torches

UV LED torches are the modern standard for black lights in Non-Destructive Testing (NDT), replacing older mercury vapor lamps. These highly portable devices use powerful LEDs to emit a specific UV-A wavelength (typically 365 nm), which is essential for illuminating fluorescent magnetic particles (MPI) and fluorescent penetrants (PT). Key advantages include instant start-up, long battery life, high intensity, and cooler operation, making them crucial tools for clearly identifying surface and near-surface defects in the field.
