200W COB LED Panel – CREE CXB3590 Full Spectrum Grow Light

Meet the **200W COB LED Panel with CREE CXB3590 chips**, the lighting system that finally retires your old HPS without sacrificing a single gram of yield. This isn't just a lamp; it's a precision tool designed to cover a 120x60cm area with full-spectrum light (3500K), drastically lowering your electricity bill while boosting resin production thanks to its superior photon efficiency.

Are you drowning in a sea of misleading LED information?

Let's be honest: the market is flooded with cheap lights promising "1000W equivalent" power for a few bucks, only to deliver disappointing harvests. There is a massive amount of contradictory opinions, myths, and unrealistic expectations surrounding LED technology, leaving many growers confused about what actually works for cannabis cultivation.

This confusion often leads to poor buying decisions. You might end up with a light that lacks penetration, causing fluffy buds, or one with a spectrum that stresses your plants rather than feeding them. The worst part? You might think "LEDs don't work," when in reality, you just haven't used the right technology. It's frustrating to invest time and money only to get a mediocre result because of bad advice.

The solution is opting for proven engineering. This **200W COB LED Panel** is a clear example of what you can really expect from high-end lighting: density, weight, and terpenes. This description is your honest guide to understanding why COB (Chip on Board) technology, specifically with CREE chips, is the game-changer you've been looking for.

Typical myths about this type of product

• Myth: LEDs don't penetrate the canopy like HPS. Reality: High-quality COB LEDs like the CXB3590 act as a point source of light, offering excellent penetration deep into the plant structure, often matching or beating HPS in focused intensity.
• Myth: You need purple (blurple) light for plants to grow. Reality: Plants thrive under full-spectrum white light (like the 3500K in this panel). It mimics natural sunlight and allows you to spot pests or deficiencies instantly, which is impossible under purple lights.
• Myth: LEDs produce zero heat. Reality: They produce significantly less heat than HID lamps, but they still emit thermal energy. The difference is that it's much easier to manage, keeping your grow room climate stable.
• Myth: More watts always equals more buds. Reality: It's about PAR (Photosynthetically Active Radiation) and efficiency. This 200W unit can outperform inefficient 400W systems because it converts more electricity into usable light, not heat.

What this product really does (and what it doesn't)

The **200W COB LED Panel** brings professional-grade efficiency to your home grow. By using two 100W CREE CXB3590 chips, it delivers a powerful, concentrated beam of light that drives photosynthesis to the max. It improves your resin production and terpene profile because the lower heat emission preserves the volatile compounds in your flowers that HPS often burns off.

It allows you to dim the power, meaning you can save even more electricity during the vegetative stage when plants don't need full intensity. However, it cannot cover a massive 1.5m x 1.5m tent by itself. It is optimized for a rectangular footprint (ideal for 120x60cm), so setting expectations correctly regarding coverage is key to getting those rock-hard buds.

Advantages and benefits when used properly

• Energy Efficiency: Because of the premium CREE chips, you get more light per watt. This means you can replace a 400W HPS setup, saving roughly 50% on your electric bill while maintaining yield.
• Full Cycle Spectrum (3500K): You don't need to change bulbs. This spectrum is perfect for both vegetative growth and flowering, simplifying your operation.
• Temperature Control: Emitting less radiant heat means you won't need to run your air extraction at full blast all the time. This makes it easier to maintain optimal VPD (Vapor Pressure Deficit) without a massive AC unit.
• Dimmable Driver: You have total control. Start seedlings at low power to avoid stress, and crank it up to 200W when the flowers start to fatten.
• Longevity: Unlike HPS bulbs that degrade quickly, these COBs are built to last for years (approx. 50,000 hours) with minimal loss of intensity.

Tips to choose well according to your expectations

This panel is ideal for the grower who values quality over sheer quantity of biomass, although it delivers heavy yields too. If you are working in a rectangular wardrobe or a closet, the form factor of this 2-chip panel is perfect. It distributes light more evenly in a 120x60cm space than a single square light would.

• If you expect maximum gram/watt efficiency, this COB panel is the right choice over older SMD LED arrays.
• If you struggle with high temperatures in summer, this light will save your harvest.
• If you want simplicity, the plug-and-play nature with a single spectrum for the whole cycle is your best friend.

For those needing to manage the environment even more precisely alongside this light, a good Humidity controller is the perfect companion to ensure your plants transpire correctly under the LEDs.

Frequently Asked Questions

Does this light really replace a 400W HPS?

In terms of yield quality and usable light for the plants, yes, it is comparable to a 400W HPS but consumes only 200W. You get similar results with half the electricity cost and much less heat.

What is the recommended distance from the plants?

For vegetative growth, keep it around 50-60cm away. For flowering, you can lower it to 30-40cm. Since it's dimmable, you can also keep it fixed and just adjust the intensity.

Can I use this for autoflowering seeds?

Absolutely. The 3500K spectrum is fantastic for the rapid life cycle of autoflowers, providing the blue light needed for structure and the red light needed for fat buds.

Do I need extra ventilation?

While it runs cooler than HPS, good airflow is still necessary for the plants. However, you won't need as aggressive extraction as you would with traditional Grow lights.

Personal Experience of Pevgrow’s CEO (Alan)

I've heard so many growers say "LEDs just don't have the punch of sodium," and honestly, that used to be true ten years ago. But when I first tested these CREE CXB3590 COBs, the difference was night and day compared to the cheap "blurple" panels. The density of the flowers really surprised me; we aren't talking about airy buds anymore, but solid rocks that look like they were grown under 600W HPS.

In my experience, the trick with this 200W panel is not to get too close too soon. The light intensity is deceptive because it doesn't feel hot on your skin, but it's very powerful for the plants. I recommend starting at 50% power during the first weeks of veg. It’s amazing to see how the plants pray to the light without heat stress. If you want a hassle-free grow with top-shelf results, this technology is currently one of my favorites.
