Choosing between traditional Mercury Lamps and advanced UV LED Curing is critical for wood coating lines. While mercury lamps were the old standard, UV LED technology has become the modern game-changer for furniture and flooring factories.

Here is a quick look at a real upgrade case from a furniture manufacturer who replaced three 12kW mercury lamps with a custom UV LED system (365nm + 395nm).

• Mercury: Consumed 36 kW/h continuously. Required long preheating and stayed at 100% power even during line gaps.

• UV LED: Consumes only 12 kW/h. Features instant on/off, drawing power only when wood passes under the light.

• Result: Saved over $8,000 USD annually in electricity.

• Mercury: Emits massive Infrared (IR) heat (80°C - 100°C), warping thin oak veneers and causing resin bleed.

• UV LED: A "Cold Light Source" (<35°C).

• Result: Rejection rate dropped from 5% to under 0.2%, protecting heat-sensitive wood.

• Mercury: Lasts only 1,000–1,500 hours. Intensity drops quickly, causing uneven curing.

• UV LED: Lasts over 20,000–30,000 hours with stable UV output.

• Result: Eliminated quarterly bulb changes, boosting production throughput by 12%.
