IUV 250 UV Curing Flood Lamp clear UV-A glass filter

Part no Description Transmission wavelengths Applications
Clear UV-A 315nm upwards Fitted as standard. Provides high intensity long wave UV-A and bright visible light. Suitable for curing UV and UV/visible light adhesives, coatings, etc.
IUV250-21 Blue UV-A 315nm to 460nm Provides high intensity long wave UV-A and some visible blue light. Suitable for UV curing. This filter cuts down on the bright visible glare from the Clear UV-A filter, but gives approximately 20% less curing energy.


When switched on, we recommend that the IUV 400 UV Curing Flood Lamp be stored on our IUV250-30 Stand, which has an integral Light Shield. This stand has mounting holes which allow it to be fixed to a bench. Alternatively, the IUV250-31 Fixed Mounting Bracket can be attached to the lamp with adjusting hand wheels, allowing the IUV 400 to be fixed to a wall, ceiling or bench and angled to suit. A 5 metre power extension cable (from lamp to power supply) is available for maximum mobility.
