70W Handheld UV Black Light Torch CG-SP-70A

The CG-SP-70A is a 70W handheld LED UV black light torch built for fast, on-site curing of UV ink, varnish, coating and adhesive. With a 5W/cm2 UV intensity and a 15-20mm best emitting distance, it delivers concentrated ultraviolet output exactly where the operator needs it, replacing bulky mercury lamp sets in screen printing, packaging, electronics bonding and inspection work.

Key Advantages

• 70W LED UV output - one 70W LED UV torch matches the drying effect of a 6000W mercury lamp while drawing a fraction of the power.
• Selectable wavelength - 365nm, 385nm, 395nm and 405nm options cover adhesive curing, printing ink and coating applications.
• Instant on and off - no warm-up and no cool-down cycle, so operators start curing the moment the torch is switched on.
• No mercury, no ozone, no VOC discharge - a clean alternative to mercury arc lamps for workshops with strict environmental requirements.
• Low temperature operation - air-cooled aluminium housing keeps heat away from PE film and thin substrates that cannot take thermal load.
• 10000 hour LED lifespan - Epistar chips and quartz lens maintain stable intensity over long production runs.
• Portable form factor - 113 x 42 x 42mm body with AC85-265V universal input, ready for 220V or 110V workshops.

FAQ

Q: Which wavelength should I choose?
A: 395nm and 385nm suit printing machine ink; 365nm is preferred for adhesives and inspection work.

Q: Can the UV intensity be adjusted?
A: No. The CG-SP-70A runs at a fixed 5W/cm2 output; total energy delivered depends on emitting time.

Q: How far should the torch be held from the material?
A: Keep the lens 15-20mm from the surface for the strongest cure.
