UV Lamps for Resin: Which Type to Choose and How to Use It
UV resin only hardens under ultraviolet light, so a UV lamp for resin is the one tool you cannot skip. The right lamp depends on what you make: tiny earrings, a tray of charms, or larger pieces and repairs. This guide compares the main types and explains how to cure UV resin properly.
UV lamp types compared
Handheld lamps
Small and portable, handheld lamps are ideal for beginners and for spot curing. Hold them over the piece and move them around to reach every part.
- Hand Held UV Light (Lite): a lightweight, budget-friendly lamp for getting started.
- Hand Held UV Light (USB): USB powered, compact and easy to use anywhere.
- Hand Held UV Light (Heavy): a stronger, more durable handheld lamp for regular makers.
Desktop lamps
Desktop lamps let you place pieces underneath and keep both hands free. They suit jewellery makers curing several small pieces at a time.
- UV Light Desktop Small 15W: a compact desktop lamp for earrings, pendants and charms.
- Desktop UV Light (Panda shape): a fun panda-shaped lamp that is popular with young makers and as a gift.
Flashlight lamps
The UV Light Flash Light Type 20W is a torch-style lamp with 20W output for larger or awkward pieces, repairs and spot curing where a desktop lamp will not fit.
Prices change, so see each product page for today’s price.
Which UV light for resin should you choose?
- Just starting with earrings and charms: a Lite or USB handheld lamp, or the 15W desktop lamp.
- Making jewellery regularly: the 15W desktop lamp for batches, plus a handheld lamp for touch-ups.
- Larger pieces, bookmarks and repairs: the 20W flashlight or the Heavy handheld lamp.
- A gift for a young crafter: the Panda desktop lamp with a small bottle of UV resin, used with adult supervision.
How to cure UV resin properly
- Pour or dome a thin layer of UV Resin 50g into the mould or frame.
- Pop bubbles with a toothpick before curing; they are fixed once cured.
- Cure under the lamp for the time on the resin label, turning the piece or moving the lamp so light reaches every side.
- Add the next thin layer and cure again. Thin layers cure fully; thick layers can stay soft inside.
- Demould and cure the back as well, since moulds can block some light.
- If the surface feels slightly tacky, give it a little more curing time.
Our UV resin guide for beginners covers the resin itself, and resin jewellery making has project ideas.
Safety with UV lamps
- Never look directly into a UV light, and do not shine it at anyone’s eyes or skin.
- Wear gloves when handling uncured resin.
- Keep the lamp clean, dry and away from water.
- Supervise children closely and store lamps out of their reach.
- Work in a ventilated space.
Looking after your lamp
Wipe resin drips off the lamp as soon as possible, before they cure. Store it in a dry place, and keep USB cables untangled. Clean the base of desktop lamps regularly so cured resin does not build up.
Frequently asked questions
Can I cure UV resin in sunlight?
Sunlight contains UV and can cure thin layers slowly, but results vary. A UV lamp is faster and more reliable.
Does a UV lamp cure epoxy resin?
No. Epoxy resin cures by chemical reaction between resin and hardener, not by UV light.
Why is my piece sticky after curing?
The layer may be too thick, or it needs more curing time. Cure in thin layers and reach every side.
