What is a UV nail lamp?

Quick science: UV lamps emit a broad spectrum of UV-A light, compatible with all gel types—but they’re sloooow. Expect each layer to cure in 2–4 minutes, and those bulbs typically last around 1,000–4,000 hours before needing replacement

Example product:

Rio 36W UV/LED Dual Nail Lamp — combines UV & LED bulbs so you can cure any polish type. Great for versatility!

What Is an LED Nail Lamp?

LED lamps emit a narrower, targeted wavelength, curing gel in a flash—usually between 30 seconds to 60 seconds per coat. The bulbs also last up to 50,000 hours, making them a long-term investment.

Example product:

Mylee Petite LED Nail Lamp — compact, stylish, perfect for mobile kit or home use.

Key differences between UV & LED lamps

Feature	UV Lamp	LED Lamp
Curing time	2–4 minutes	30–60 seconds
Gel compatibility	Works with all gels	Works only with LED-compatible gels
Bulb lifespan	~1,000–4,000 hours (replace often)	Up to ~50,000 hours (rarely replace)
Cost	Budget-friendly upfront	Slightly pricier but worth it long-term
UV exposure	More exposure per session	Less exposure, deemed safer

Which should you choose?

For beginners / home use

✅ Go LED—faster sessions, safer exposure, less bulb hassle.

For pro nail techs / training kits

✅ Hybrid or UV+LED is a winner. Flexibility is everything when clients bring their own polishes.

For sensitive skin clients

✅ LED emits less UV, so it’s the gentler choice. Pair with SPF gloves if concerned

What the experts say

“Most professional LED and UV nail lamps are at least 36 watts. This is because higher-watt bulbs can cure gel polish faster – which is very important in a salon setting. For LED polish, a high-wattage LED lamp can cure it within seconds, while a UV lamp will always take a little longer.”

• Safety check: Dermatologists say both emit minimal UVA—roughly same as a short walk outside. Still, SPF gloves = smart
