Dorhui 60W UV Exposure Unit
The Dorhui 60W unit uses a 395 nm wavelength, designed to burn screens quickly with uniform illumination. Exposure times can drop to about 3–5 minutes depending on emulsion thickness. It includes an adjustable height and angle stand, and a 360° rotating light to minimize dead spots. The light is positioned to evenly cover larger areas, making it a solid choice for small to medium screens and cyanotype work.
Best for: Hobbyists and small shops needing a compact, adjustable unit with quick exposure.
Why chosen: It provides a balance of power, adjustability, and efficient light distribution for consistent results.
Caution: Exposure times vary with emulsion thickness, so perform a test exposure before running a full batch.
Caydo 100W LED Exposure Unit
The Caydo 100W model provides a strong, uniform 395 nm exposure with a built-in timing device. It’s suitable for larger screens and frames, covering 10 x 14 inches up to 20 x 24 inches. The timing feature supports exposure from 0.5 to 9.5 minutes, turning off automatically when the set time ends. This helps prevent overexposure and saves material. The unit’s frame is compatible with multiple screen sizes for flexible workflows.
Best for: Medium to large screens and users who value precise exposure timing and automation.
Why chosen: The combination of high power, broad frame compatibility, and a practical timer makes it a workhorse for regular production.
Caution: Timed exposure requires occasional calibration to ensure consistency across batches.
Feghezja 100W UV Exposure Unit
The Feghezja unit delivers 395 nm UV light with 100W power, designed for uniform and stable illumination. It supports quick cure times of about 2 minutes, depending on emulsion thickness. A robust fixing clamp and a 360° adjustable stand reduce tipping and blind spots, enabling even curing on large or irregular items. The stand design helps position the lamp at the optimal angle and height for diverse screens and materials.
Best for: Users needing a sturdy setup for larger items and varied exposure angles.
Why chosen: The combination of a strong light source and a stable, rotatable stand minimizes shadows and uneven exposure.
Caution: The larger stand and clamp may require more table space in tighter studios.
Caydo 50W LED UV Screen Printing Light
This 50W Caydo light operates at 395 nm and includes a timing device that supports exposure from 1 to 99 minutes. It’s a straightforward option for beginners or smaller frames, offering reliable, repeatable exposure without unnecessary complexity. The system is designed to fit frames up to 16 x 12 inches, making it a practical entry point for hobbyists or small-batch projects.
Best for: Beginners and small-frame screen printing tasks.
Why chosen: Its simple operation and dependable exposure time help new users build consistent results quickly.
Caution: The smaller exposure area may not suit larger screens, and users should verify frame size compatibility before purchase.
Caydo 54 Pieces Screen Printing Kit
This all-in-one Caydo kit includes a 50W exposure light, a complete set of screen printing materials, and accessories. It comes with three screen frames, six inks, photo emulsion, and various tools to support a full workflow from prep to printing. The 50W exposure lamp provides stable and even exposure, while the included emulsion and ink enable immediate testing and production.
Best for: Complete starter kits for new users building a full screen printing workflow.
Why chosen: It provides everything needed to begin screen printing, reducing the need to source multiple items separately.
Caution: Because it includes many components, the kit may be larger and less portable than single-light options.
Buying Guide: Light Table And Exposure Unit Considerations
- Screen size compatibility: Choose a unit that covers the largest screen you plan to expose. Look for models that explicitly list supported frame sizes.
- Wavelength and exposure speed: Most screen emulsions respond to around 395 nm. Higher wattage speeds exposure but may cause more heat; balance power with emulsion thickness and materials used.
- Stand adjustability: A flexible stand (height, angle, and 360° rotation) helps minimize shadows and ensures even curing on irregular items.
- Timing features: A built-in timer helps enforce consistent exposure and prevents overexposure. Some models remember last settings, which aids repeatability.
- All-in-one kits: Starter kits bundle ink, emulsion, and frames. They are efficient for beginners but may be bulkier and require more space.
- Durability and protection: Look for a stable base, secure clamps, and quality lens or glass covers to reduce light loss and protect the emulsion.
Frequently Asked Questions
- What exposure time should I expect for standard photo emulsion? It varies with emulsion thickness, but many systems target 2–5 minutes for standard emulsions with 395 nm light. Always run a test exposure first.
- Can I use these lights for cyanotypes? Yes. The 395 nm UV exposure aids cyanotype development, and a large stand helps cover cyanotype papers evenly.
- Is higher wattage always better? Not necessarily. Higher wattage speeds exposure but can introduce more heat and larger energy consumption. Match wattage to your screen size and material.
- What should I consider for large-format screens? Prioritize units with wide exposure areas and adjustable stands to avoid dark spots and ensure uniform exposure across the entire frame.
- Are all-in-one kits worth it? They are convenient for beginners who need everything in one package, but they may be less portable and require more storage space.
- Do these units require calibration? Periodic calibration helps maintain consistent exposure across sessions. Keep a log of test exposures to track changes over time.
