Caydo 2-Pack 50W LED UV Exposure Lights
The Caydo 2-Pack 50W LED UV exposure units are designed for flexibility and scalability. Each unit delivers 395 nm wavelength with uniform illumination, supporting exposure times of 3–5 minutes depending on emulsion thickness. The package includes two 50W lamps, two PVC stands, and multiple mounting accessories to support both small 10 x 14-inch screens and larger 20 x 24-inch frames when used together. A 2-in-1 design enables independent or combined operation for varied production runs, making them suitable for cyanotype and standard screen printing tasks.
Key considerations: ease of setup, compatibility with standard frames, uniform exposure, and maintenance needs. This option is practical for shops that alternate between smaller runs and larger frames, reducing the need for multiple separate systems.
Caydo 100W UV Exposure Unit for Screen Printing
The Caydo 100W UV exposure lamp provides a higher power option for faster cure times, with a 395 nm wavelength and uniform light distribution. Typical exposure time is around 1.5 minutes, depending on emulsion thickness. A built-in timing device supports durations from 0.5 to 9.5 minutes, with increments of 0.5 minutes. The unit features a wide exposure area compatible with screens from 10 x 14 inches up to 20 x 24 inches, enabling efficient handling of larger frames without needing multiple lamps.
Key considerations: exact exposure time by emulsion, timer reliability, and frame size compatibility. This model suits users seeking quicker curing and a robust timer feature for repetitive workflows.
Dorhui 50W LED Exposure Unit for Screen Printing
The Dorhui 50W UV exposure lamp uses a 395 nm wavelength to deliver uniform illumination with an exposure time of approximately 3–5 minutes, depending on emulsion thickness. The unit’s adjustable height and 360° rotating lamp head enable precise targeting of the emulsion layer and minimize dead zones. The light stand supports flexible positioning, making it suitable for various screen sizes. This setup emphasizes adaptability for different project scales and environments, from small batch tests to mid-sized production runs.
Key considerations: adjustable position accuracy, reach of the stand, and operating noise or heat during longer sessions. It is a solid choice for operators who need versatile angling and reliable curing performance.
Caydo 50W LED UV Exposure Unit with Retractable Stand
This Caydo model offers a 50W UV exposure lamp with a retractable and adjustable stand, designed to accommodate different screen sizes and heights. The lamp emits at 395 nm for efficient curing and features adjustable height and angle to align precisely with the emulsion. With a compact footprint, it suits home studios and small shops needing flexible setup without sacrificing exposure consistency. The user interface emphasizes quick on/off operation for streamlined workflows.
Key considerations: stand stability, ease of height adjustment, and compatibility with standard frames. This option is ideal for users who value space efficiency and adjustable positioning in a single package.
Ecoofor 2 Pcs 50 W LED UV Light for Screen Printing
The Ecoofor kit includes two 50W LED UV exposure lights with dual stands, a comprehensive set of mounting hardware, and an instruction manual. The 395 nm UV lamps offer rapid curing for photosensitive emulsions and cyanotypes, typically within 3–5 minutes, depending on emulsion thickness. The two-light setup provides flexibility for larger screens or parallel exposure tasks, enabling faster throughput in small to mid-sized production contexts.
Key considerations: full kit value, simultaneous two-light operation, and assembly requirements. This pair-based option is well-suited for users needing higher throughput without investing in separate systems.
Buying Guide: Key Purchase Considerations
- Wavelength and power: Most screen printing emulsions cure at around 395 nm. Higher wattage (50–100W) generally reduces exposure time, but uniformity and cooling are important to avoid hot spots or uneven curing.
- Exposure area compatibility: Ensure the unit supports your screen sizes (commonly 10 x 14 inches to 20 x 24 inches). Some models offer two-light configurations for larger frames.
- Timing features: A built-in timer helps prevent over-exposure. Look for increments that match your typical emulsion thickness and a memory function for repeat usage.
- Stand design and adjustability: Adjustable height, angle, and stable stands improve exposure accuracy. Retractable or foldable stands save workspace space.
- Portability and setup: For hobbyists or small studios, compact units with simple assembly reduce downtime between jobs. Dual-light kits can increase throughput for bigger runs.
- Durability and materials: Iron or metal-framed units with rust-resistant coatings tend to be more durable for long-term use. Ensure user manuals provide clear installation steps.
- Maintenance and safety: Check for heat generation, ventilation needs, and easy access to replaceable LEDs or tubes. Follow safety guidelines for UV exposure.
- Cost of ownership: Evaluate total package value (lamps, stands, cables, and manuals). A two-light kit may offer better value for shops handling mixed job sizes.
