Fission LED 240W V2.0 Grow Light – Full Spectrum Dimmable Panel

The Fission LED 240W V2.0 is much more than just a light panel; it is a precision tool designed to transform your indoor cultivation into a high-performance laboratory. This system offers you a full spectrum that mimics natural sunlight, including UV and IR, ensuring that your plants express their maximum genetic potential from the first root to the last bud, all while keeping your electricity bill under control.

Why settle for less when you can have total control?

Problem: Many growers underestimate the importance of spectrum and intensity control, using fixed-power lights or outdated technologies that generate too much heat. This forces them to battle high temperatures, install noisy fans, and limit their growing cycles to colder months, missing out on the potential of a year-round harvest.

Agitation: Sticking to inefficient lighting doesn't just spike your electricity costs; it stresses your plants and stunts terpene production. Every degree of excess heat is a gram lost, and the lack of proper spectrum regulation means you are essentially feeding your plants "junk food" instead of a balanced diet, resulting in airy buds and lackluster flavors.

Solution: The Fission LED 240W V2.0 solves this equation with its high efficiency (2.43 µmol/J) and passive cooling system. It allows you to cultivate in silence, manage heat effortlessly, and provide the exact light intensity needed thanks to its 4-step dimmer. It is the versatile engine that adapts to your environment, not the other way around.

Use case 1: The King of the 80x80 Tent

This is the natural habitat for the Fission 240W. If you are running one of our Grow tents 80X80, this panel is mathematically perfect for you. It covers the footprint edge-to-edge without creating hot spots, ensuring that even the plants in the corners get the same love as the ones in the center.

In this scenario, you can start with the dimmer at 40% for seedlings, ramp it up to 60-80% during vegetation, and blast full 100% power during flowering. The result? Dense, rock-hard buds without the need for an industrial-sized extractor fan, keeping your operation stealthy and quiet.

Use case 2: The Summer Saver & Mother Keeper

Do you stop growing in July because your HPS turns your room into an oven? The Fission V2.0 changes that. Its passive dissipation technology means it emits significantly less radiant heat towards the canopy. This makes it the ultimate choice for summer runs or for growers living in warmer climates who want to keep the quality high without burning off the terpenes.

It is also an exceptional tool for maintaining mother plants or a vegetative closet. By running it at 40% or 60%, you provide high-quality Full spectrum led grow lights that keep internodal spacing tight and plants healthy, ready for cloning whenever you need them, with minimal power draw.

How to choose the best use for you

Not sure if this is the right fit for your setup? Here is a quick guide to help you decide:

• If you are a home grower with limited space (up to 1m²): This is your main light. It replaces a 400W HPS while consuming nearly half the power.
• If you value silence and discretion: The fanless design makes it invisible to the ears, perfect for bedroom grows or apartments.
• If you are an advanced grower: Use it to supplement dark corners in a larger room or as a dedicated vegetative light to speed up your cycles.

Advantages and benefits that show up in every case

• Total Control: The built-in dimmer (40%-60%-80%-100%) puts you in the driver's seat, allowing you to save electricity when full power isn't needed.
• Silent Operation: No moving parts means zero noise and fewer things that can break. Your peace of mind is included.
• Superior Resin Production: The inclusion of UV (395nm) and Far Red (730nm) diodes stimulates the production of trichomes and essential oils.
• Plug & Play: Lightweight (3.05 kg) and easy to hang. Don't forget to check your water quality with reliable PH meters to ensure your plants can absorb all the energy this light provides.
• Longevity: With a lifespan of 50,000 hours, you are set for years of continuous harvesting.

Frequently Asked Questions

How high should I hang the Fission LED 240W?

For seedlings, start around 50-60 cm at 40% power. In vegetative stage, 40-50 cm at 60-80%. For flowering, you can get as close as 30 cm at 100% power, always monitoring the plant's response.

Does it produce a lot of heat?

Compared to HPS or CMH, it runs very cool. However, all electronics produce some heat. The passive aluminum heatsink dissipates it upwards, so a small clip fan blowing over the top helps keep the unit cool and efficient.

Is it suitable for the entire cycle?

Absolutely. The full spectrum is designed to cover everything from germination to harvest. The 3000K and 5000K white LEDs provide the base, while the 660nm Red boosts flowering explosiveness.

Do I need a ballast?

No, the driver is integrated into the unit. You just plug it into the wall and you are ready to grow.

Personal Experience of Pevgrow’s CEO (Alan)

I've tested the Fission 240W in a standard 80x80 tent during a hot Spanish summer, and honestly, the difference in temperature management compared to my old sodium setup was night and day. What I really appreciate is the dimmer; being able to dial it down for seedlings without raising the light constantly is a huge comfort.

My favorite aspect? The silence. You can sleep in the same room with the tent and not hear a thing. If you are looking for quality buds without the headache of heat stress or noise, this panel is a solid 10/10 investment for the modern home grower.
