Weissman EVO V1 LED Grow Light – Evocrop Full Spectrum COB 200W & 300W

The Weissman EVO V1 LED Grow Light by Evocrop is designed to be the definitive tool for indoor growers who want to leave inefficient HPS lamps behind and step into high-performance cultivation. This panel isn't just a light source; it's a yield generator that uses COB (Chip on Board) technology to deliver a full spectrum identical to sunlight, ensuring your plants produce denser buds, more resin, and richer terpene profiles.

Are you tired of hearing contradictory advice about cheap vs. expensive LEDs?

There is a massive amount of noise in the growing community. Some say you need to spend a fortune on top-tier bars to get decent results, while others buy cheap, purple "blurple" lights from general marketplaces and end up with wispy, airy flowers. This confusion often leads growers to make poor investments, buying lights that either lack the power to penetrate the canopy or are overkill for their tent size, resulting in heat issues and wasted electricity.

The Weissman EVO V1 is the reality check you need. It sits perfectly in the sweet spot: it offers professional-grade spectrum and intensity thanks to its Bridgelux COBs, but at a price point that makes sense for the home grower. This description is your honest guide to understanding exactly how this equipment works, stripping away the hype so you can focus on what matters: the harvest.

Typical myths about COB LED panels

• Myth: "LEDs don't produce as much weight as HPS lights."
  Reality: High-quality COBs like these have a better light spectrum (Full Spectrum) than HPS, often exceeding the 1g/watt ratio because the plant uses the light more efficiently.
• Myth: "You need purple light for plants to grow."
  Reality: Plants thrive under full-spectrum white light (3500K). It mimics the sun and allows you to spot deficiencies or pests much easier than under purple lights.
• Myth: "200W LED is the same as 200W HPS."
  Reality: In terms of power draw, yes, but in terms of output (PAR), a 200W LED like the Weissman usually outperforms a 250W HPS because it directs all light downwards without relying on reflectors.
• Myth: "LEDs produce zero heat."
  Reality: All electronics produce heat. While cooler than HPS, powerful COBs still generate warmth, which is why the Weissman EVO V1 includes active fan cooling to keep temps stable.

What the Weissman EVO V1 really does (and what it doesn't)

The Weissman EVO V1 is engineered to provide deep canopy penetration. Unlike older diode boards that scatter light, the COB technology concentrates light intensity, ensuring that even the lower branches of your feminized seeds receive the energy they need to fatten up. It delivers a spectrum ranging from 380nm to 780nm, covering the entire PAR range, which triggers rapid vegetative growth and explosive flowering.

However, it is important to manage expectations. This is a compact, high-intensity unit. It is not a bar-style light that spreads intensity over a massive footprint; it is designed to punch hard in specific areas (80x80cm for the 200W and 100x100cm for the 300W). It actively dissipates heat through fans, so while it runs cooler than a sodium lamp, it is not completely silent, though at 26dB, it's quieter than a whisper.

Advantages and benefits when used properly

• Bridgelux COB Technology: You get high-intensity light penetration, meaning fewer "popcorn buds" at the bottom of the plant and more solid colas.
• Dimmable Power (50% / 100%): You can save electricity during the seedling and early veg phase by running it at half power, then switch to 100% for the bloom phase.
• Full Spectrum (3500K): Your plants produce more complex terpene profiles compared to narrow-spectrum lights, resulting in better tasting and smelling crops.
• Plug & Play Simplicity: No ballasts, no complex wiring. Just hang it in your grow tents, plug it in, and grow.
• IP67 Protection: The unit is sealed against humidity and dust, ensuring durability even in the humid environment of a grow room.

Tips to choose well according to your expectations

Choosing the right model depends entirely on your grow space. If you are working with a standard 80x80cm tent, the 200W model is your perfect match, providing optimal coverage without light stress. If you have a slightly larger space, like a 1m x 1m or are upgrading from a 300W Grow light LED of an older generation, the 300W model gives you that extra intensity needed to maximize yield.

• If you expect silent operation: Remember this unit has fans. They are quiet, but not passive.
• If you want maximum yield: Keep the light at the correct distance (approx 40-50cm in bloom) to avoid light burn, as COBs are intense points of light.
• If you want longevity: The 50,000-hour lifespan means you won't be changing bulbs every few crops like with HPS.

Frequently Asked Questions

What is the recommended hanging distance?

For vegetative growth, start around 50-60cm. In flowering, you can lower it to 30-40cm. Watch your plants; if leaves curl up, raise the light.

Does it come with the hanging kit?

Yes, it typically requires pulleys or yo-yos (sold separately or included depending on the specific promo), but the unit is ready to hang. It connects directly to the mains.

Can I use the 300W model in a 60x60cm tent?

It is possible, but you would likely need to run it at 50% power or keep it very high up to avoid heat issues and light stress. The 200W is much better suited for smaller spaces.

Is it suitable for autoflowering plants?

Absolutely. The full spectrum is perfect for the entire life cycle of autoflowers, from seed to harvest, without needing to change the light schedule or spectrum.

Personal Experience of Pevgrow’s CEO (Alan)

I've seen a lot of skepticism around COB panels because the market was flooded with cheap knock-offs a few years ago. But when I tested the Weissman EVO V1, I was genuinely surprised by the punch it packs. The Bridgelux chips are no joke—they deliver a light intensity that penetrates deep into the canopy, something that many panel LEDs struggle with.

In my experience, the 300W model is a beast for a 1-square-meter tent. If you manage your ventilation well, you can pull yields that rival 400W HPS systems easily, but with better resin quality due to the spectrum. It's a solid, no-nonsense piece of gear for growers who want performance without paying the "hype tax" of big-name brands.
