Frolight vs. Candles: A New Way to Protect Your Crops from Frost

Frost candles… A true classic in the vineyard world. Easy to understand, relatively accessible, and for years, they’ve been the go-to solution for those freezing nights. Their glowing flames lighting up the vines in the dark have almost become iconic. And yes — they do work, up to a point.

But as useful as they are, candles aren’t quite cutting it anymore when it comes to today’s expectations for performance, convenience, and sustainability.

👉 And that’s where the magic of Frolight steps in.

Want to discover a smart, automated, and seriously stress-free solution? Let me tell you about Frolight — you're going to love it.

The Birth of Frolight: Where Smart Tech Meets Agricultural Know-How

It all started back in 2019, with one simple but bold idea:

"What if we used infrared heat to protect crops from frost, in a precise and intelligent way?"

That question kicked off years of research and development, aiming to create a solution that would be efficient, sustainable, automated, and easy to use.

Frolight, Innovation Born from Frost

Tested, patented, and launched in 2021, Frolight quickly expanded into over 12 countries. Today, with 600 km of infrared tubes installed, it’s become a global benchmark in eco-friendly, automated frost protection.

Why Frost is a Real Threat to Growers

When temperatures drop below freezing, buds and young shoots are the first to suffer. From just -2°C, damage begins — and at -4°C or colder, you could lose a big part (or even all) of your harvest.

And it’s not just about temperature. Humidity, wind, and thermal inversion all play a role. That’s why you need a solution that’s reliable, proactive, and precise — and why candles often fall short these days.

Candles: The Traditional Method — But at What Cost?

For years, frost candles were the most accessible solution. You’ve probably seen them — little paraffin pots lined up in vineyards and orchards, lit as night falls.

Here’s the catch:

• Protects down to -3.5°C, but not beyond
• Requires 400 to 500 candles per hectare
• Labor-intensive, especially during the night
• High environmental impact (CO₂ emissions, smoke, and burning paraffin)
• No automation, meaning you’re on weather-watch duty all night

Frolight: A Cleaner, Smarter, More Efficient Solution

Frolight flips the script — instead of heating the air around the crops, it directly warms the plants using an intelligent system of infrared tubes.

The result? Targeted heat, optimized energy use, zero human intervention, and reliable protection down to -6°C, even during extreme frost.

Why Frolight Makes All the Difference:

• ✅ No night labor — fully automated activation
• ✅ Eco-friendly — no smoke, no combustion
• ✅ Works in any weather — no thermal inversion needed
• ✅ Simple installation and intuitive use
• ✅ No permits required — just plug and protect

Conclusion: The Choice is Clear

Yes, candles served us well. But now, there’s a better way. Frolight brings you a new generation of frost protection: automated, eco-friendly, cost-effective, and reliable.

And best of all? You sleep peacefully while Frolight watches over your crops.
