  • Service life exceeds 10× traditional mercury lamp equivalents

Hetai Tech 400W UV Curing Lamp

The Hetai Tech 400W UV LED curing lamp is a portable unit built for rapid curing of UV shadowless adhesives. It uses imported UV LED chips to deliver high energy with stable output and uniform illumination. The cold light source produces no heat radiation, keeping the illuminated surface cool during operation. It reaches 100 percent power instantly without any preheating delay.

Who this suits and who should look elsewhere

This lamp suits technicians and production lines that need fast, consistent curing for LCD edge sealing, film printing or inkjet photo printer heads. It is not for buyers who require a mains-powered industrial conveyor system or a unit with a built-in timer and intensity meter. It also does not fit applications needing deep penetration beyond the 395nm wavelength range.

Deciding specification: 395nm wavelength

The emitted wavelength of 395nm determines which UV adhesives and inks will cure correctly with this lamp. Match this figure to the material datasheet before purchase. If the chemistry requires 365nm or 410nm activation, this unit will not provide full cure depth.

Questions about this item

How often will the UV LED chip need replacing compared with a traditional mercury lamp?

The LED light source lasts more than 10 times longer than a traditional lamp machine, so replacement intervals are dramatically extended.

What limits continuous output during long curing sessions?

The lamp delivers 100 % UV output instantly with no pre-heat, and its cold-light design keeps surface temperature low, so thermal throttling is not the limiting factor.

How much heat and noise does the 400 W unit produce when running all day?

It operates as a cold light source with no heat radiation, low heat generation and no fan noise, keeping the illuminated surface temperature low.
