ST-45A is specifically designed for aerospace. This type of NDT UV lamp features 5 UV-A LEDs and no white light LED. The intensity has been adjusted to never exceed 4,500 µW/cm2 @ 38cm and is compliant with ASTM UV-A intensity levels.

Features:
100% solid state circuitry ensures that it works properly in strong magnetic fields
Switch function between UV light and White light
Safe, pure UV-A content with no UV-B or UV-C; almost no visible light.
Standard Intensity: 4.500 µW/cm2 @ 38cm
Large coverage area of up to 20cm, with a minimum UV-A intensity of 1.200 µW/cm2
Unique mechanical cooling system keeps the LEDs cool maintaining optimum light output during extended use.
Each LED has an estimated 50.000 hour lifespan
The start button provides instant power and the light is operated with a multifunctional switch - UV/OFF/White light - on the pistol handle for ease of use.
Equipped with a current regulator to keep the intensity stable when the battery fades
Wavelength specifications for FPI and MPI, IP43 approved for water spray and external bodies.
