# **How to Choose a UV Pen Light for Curing UV Resin Fast When Fly Tying, for Making Fishing Flies**
When it comes to fly tying, UV resin has revolutionized the way anglers create durable, high-quality fishing flies. However, the curing process is just as crucial as the application itself. A **UV pen light** is an essential tool for quickly hardening UV resin, ensuring your flies are strong, glossy, and ready for action.
But not all UV lights are created equal. Choosing the right one can make the difference between a perfectly cured fly and a sticky, half-set mess. In this guide, we’ll break down the key factors to consider when selecting the best **UV pen light** for fly tying, ensuring fast, reliable curing every time.
## **1. Wavelength Matters: 365nm vs. 395nm**
UV resin cures under specific wavelengths of ultraviolet light, typically **365nm or 395nm**.
– **365nm UV Light**:
– More effective for deep curing, especially with thicker resin layers.
– Produces less visible light, reducing eye strain during prolonged use.
– Slightly slower curing time but ensures thorough hardening.
– **395nm UV Light**:
– Faster curing on the surface, ideal for thin resin applications.
– Brighter visible purple light, which can be harsh on the eyes.
– May not penetrate as deeply as 365nm.
For fly tying, where precision and quick curing are key, **365nm is often the better choice**, especially when working with layered resin.
## **2. Power Output (mW/cm²) – The Stronger, The Faster**
The **power output** of a UV pen light determines how quickly it cures resin. Measured in **milliwatts per square centimeter (mW/cm²)**, higher numbers mean faster curing.
– **Low Power (5-50 mW/cm²)**:
– Budget-friendly but slow (may take 30+ seconds per layer).
– Risk of incomplete curing if resin is too thick.
– **Medium Power (50-100 mW/cm²)**:
– Good balance between speed and cost.
– Cures most UV resins in 10-20 seconds.
– **High Power (100+ mW/cm²)**:
– Professional-grade, cures resin in **5-10 seconds**.
– Best for frequent fly tyers who need efficiency.
For fast, reliable curing, **aim for at least 80-100 mW/cm²**—especially if you’re using thicker resin formulas.
## **3. Battery Life & Rechargeability**
A dead UV light mid-project is frustrating. Consider:
– **Rechargeable vs. Replaceable Batteries**:
– **Rechargeable (USB-C/Lithium)**: More eco-friendly and cost-effective long-term.
– **AAA/Button Batteries**: Convenient for backup but may need frequent replacement.
– **Runtime**:
– A good UV pen light should last **at least 30-60 minutes** of continuous use.
– Look for models with **auto-shutoff** to conserve battery.
## **4. Beam Focus & Ergonomics**
Since fly tying requires precision, the **beam focus** of your UV pen light is critical.
– **Narrow Beam (5-10mm)**:
– Concentrated light for small, detailed work.
– Prevents accidental curing of surrounding areas.
– **Adjustable Focus**:
– Some models allow beam widening for larger applications.
Additionally, **ergonomic design** matters—especially for long tying sessions. A lightweight, pen-style light with a **comfortable grip** reduces hand fatigue.
## **5. Durability & Water Resistance**
Fly tying can be messy, and UV lights often get exposed to resin, water, or drops. Look for:
– **Metal Housing**: More durable than plastic.
– **Water-Resistant Design**: Protects against accidental spills.
