Fission Led 480W V2.0 Light – Mixed Spectrum Quantum Board for 1.2m Tents

The Fission Led 480W V2.0 Light is the definitive lighting upgrade for your indoor grow, designed to deliver professional-grade density and resin production using advanced Quantum Board technology. This mixed spectrum luminaire ensures your plants receive the exact light intensity they need from seedling to harvest, maximizing efficiency in a 120 x 120 cm space without the heat issues of older technologies.

Is your grow room turning into a sauna every time the lights turn on? You know the drill: you wake up to check your girls, and the thermometer is spiking. You're constantly battling heat stress, your extractor fan is running at full blast like a jet engine, and you're dreading the electricity bill at the end of the month. It feels like you're working for your equipment rather than your equipment working for you.

Continuing with inefficient lighting is burning a hole in your pocket and stressing your plants. Every degree of excess heat burns off terpenes, and every decibel of noise risks your discretion. It's frustrating to pour time and nutrients into a crop only to get airy, fluffy buds because the light distribution was uneven or the heat stunted their growth. You're leaving yield on the table.

The Fission Led 480W V2.0 flips the script completely. By switching to this high-efficiency LED, you instantly drop the room temperature, silence the noise (thanks to passive cooling), and bathe your canopy in uniform, penetrating light. Suddenly, your environment is stable, your plants are praying to the light, and you're set up for a record-breaking harvest with significantly less hassle.

What the Fission Led 480W V2.0 Light delivers exactly

This isn't just a bulb; it's a complete lighting system engineered for the modern grower who wants results without the headache. Here is what makes this unit a beast:

• Quantum Board Technology: Ensures even light distribution, eliminating hot spots and shadow zones.
• Mixed Spectrum: Perfectly balanced for both vegetative growth and flowering stages.
• Adjustable Dimmer: 4 power settings (40%, 60%, 80%, 100%) to match the plant's life cycle.
• Passive Cooling: A robust aluminum heat sink dissipates heat without noisy fans that can break down.
• High Efficiency: 2.43 μmol/J with a PPF of 1166 μmol/s, meaning more light for less electricity.

How your routine changes from now on

Once you hang the Fission Led 480W, the vibe in your grow room changes. Gone are the days of constantly adjusting cool tubes or fighting with air conditioners. Because this light runs cooler than HPS or older LEDs, your climate control becomes a breeze. You can get closer to the canopy without burning the tips, allowing for deeper light penetration and denser lower buds.

Your daily checks become a pleasure rather than a chore. With the dimmer knob, you have total control. Start seedlings at 40% to save energy, and crank it to 100% when the flowers start stacking. It’s a set-it-and-forget-it solution that gives you back your peace of mind and lets you focus on what matters: keeping your plants happy.

Advantages and benefits you'll notice from day one

• Massive Energy Savings: Cut your electric bill significantly compared to 600W HPS systems while getting better light output.
• Silent Operation: No fans means zero noise, keeping your operation discreet and quiet.
• Full Cycle Solution: No need to change bulbs between veg and bloom; the mixed spectrum handles it all.
• Bigger, Harder Buds: The optimized spectrum and high PPF lead to tighter internodes and heavier flowers.
• Longevity: LEDs last for years without losing intensity, unlike HID bulbs that need replacing every few crops.

Tips to combine it with other Pevgrow products

To truly unlock the potential of the Fission Led 480W, you need to pair it with the right nutrition and environment. Since LEDs don't evaporate as much water as HPS lights, you might need to adjust your watering schedule.

• Nutrition: With the increased metabolism under this light, your plants will be hungry. A solid nutrient line like Hesi Fertilizers ensures they have the fuel to match the light intensity.
• Environment: While the light runs cool, good airflow is still key. Ensure your extraction is dialed in to replenish CO2.
• Harvest: When you finally chop down those dense colas, make sure you have the right gear for Harvesting and Drying Marijuana to preserve those terpenes you worked so hard for.

Frequently Asked Questions

What size grow tent is this light best for?

The Fission Led 480W V2.0 is optimized for a 120 x 120 cm coverage area. It provides perfect edge-to-edge light distribution in this space.

Do I need to add extra fans for cooling?

No, the unit uses passive cooling technology with a high-quality heat sink. It dissipates heat naturally, so no built-in fans are needed, making it silent and reliable.

How far should I hang the light from my plants?

We recommend a distance of 40 to 60 cm from the canopy. You can use the dimmer to reduce intensity if the plants are young, rather than moving the light further away.

Is this light suitable for autoflowering strains?

Absolutely. For autos, you can run this light on a 20/4 cycle from seed to harvest. The mixed spectrum is perfect for their rapid life cycle.

Personal Experience of Pevgrow's CEO (Alan)

"I've seen a lot of growers hesitate to switch from HPS to LED because of the price tag, but the Fission 480W V2.0 is the game changer. I set this up in a 1.2m tent with four large photoperiod plants. The first thing I noticed? The silence. It's weirdly quiet if you're used to buzzing ballasts.

But the real magic happened in week 5 of flowering. The resin production was off the charts compared to my old setup, likely due to the spectrum quality and lower heat stress. I ran it at 100% power during the peak bloom, and the buds were rock hard right down to the lower branches. If you want to upgrade your game without spending a fortune on the most expensive brands, this is the sweet spot of performance and value."
