The VIVOSUN VS4000 LED Grow Light has been a game-changer for my indoor gardening setup. Here’s why I’m giving it five stars: High-Quality LEDs: The Samsung LM301 diodes provide excellent light output and efficiency. The full spectrum light is perfect for all stages of plant growth, from seedling to bloom. My plants are thriving under this light, showing vigorous growth and vibrant health. Dimmable and Versatile: The dimmable feature is incredibly useful, allowing me to adjust the light intensity according to the needs of my plants. This flexibility is perfect for managing different growth stages and ensuring optimal light conditions. Durable and Well-Built: The build quality of the VS4000 is impressive. It feels sturdy and durable, with a solid construction that gives me confidence in its longevity. The included hanging kit makes it easy to set up and adjust the height as needed. Energy Efficient: Despite its powerful output, the VS4000 is energy-efficient, helping to keep my electricity costs down while providing ample light for my plants. It runs cool, preventing any issues with overheating. Additional Accessories: The included glasses are a nice touch, providing eye protection from the intense light. The user manual is clear and helpful, making the setup process straightforward. Great Coverage: The light covers my 4x4 grow tent perfectly, providing even light distribution across the entire canopy. This ensures that all my plants receive adequate light without any dark spots. Overall, the VIVOSUN VS4000 LED Grow Light has exceeded my expectations. It offers high-quality lighting, energy efficiency, and versatile features that cater to all my indoor gardening needs.

Well built light and assembly. Fairly lightweight and easy to install. I like how it connects to the main controller unit using the included connector cable. I will continue to purchase vivosun products as their system works well and is intelligent.

These lights work great. I used 50% light intensity during seedling and veg stage for my tomato plants and then switched to 75% when I went into Flowering stage for the first 4 weeks. Then after defoliating, I went to full 100% for the remainder of the flower cycle. The best bud set and tomatoes I have ever gotten!!

We purchased this 200w grow light to replace a 2 foot 4 x T5 fluorescent grow light and the difference is... night and day. It comes with a dimmer knob with: 25%/50%/75%/100% and we leave it on 25% even with a large number of leafy plants beneath. At full power, the room is painfully bright and we'd need to wear sunglasses just so sit on the couch! The good: + Staggering brightness at higher power settings + Good efficiency (easily twice the efficiency of our previous fluorescent grow light) + Generates very little heat and no audible hum or noise. + Multiple emitter spectrums keep our plants very happy. + COLOR is pleasant; you can sit comfortably near the lamp without the 'Blurple' so many old ones had. The Bad: - The power cord is shorter than the model we replaced. - 100% power is too bright to sit in the room with. Really. - Only time will tell how good Vivosun's engineering was, hopefully, the arrays live up to their LXX numbers.

I just barely set up the VIVOSUN VS1500 grow lights, and so far, I'm impressed with their performance. These lights are incredibly bright, providing ample coverage for my indoor plants. The build quality is top-notch; they have a sleek design that feels durable and well-made. One of the standout features is the ability to daisy chain multiple units together, which is a big plus for expanding your setup. This feature makes it easy to manage multiple lights efficiently. However, there is a downside, cable management. With the number of cables required for the lights and daisy chaining, things can get messy pretty quickly. It’s a bit of a hassle to keep everything tidy, especially if you’re particular about maintaining an organized space. Overall, the VIVOSUN VS1500 is an excellent grow light that delivers on brightness and quality, with just a minor drawback in cable management.

I've purchased a lot of Vivosun's products for their competitive prices but their quality has never failed me. This set of light is hands down gorgeous and efficient. I use it in my 5x5 grow tent, and the plants are doing great under it. The things I love about this light: + The affordable price. Nothing beats Vivosun's in that matter. A comparable light with Samsung diodes could run easily over $500. + Look at how thin and lightweight it is in the attached photos. Amazing!! + It is so bright you NEED to make sure to wear glasses. My plants are loving it. Light has the dimming function; simply turn the knob to set it at 40%, 50%, 60%, 80% and 100% capacity. + It's completely quiet. No more annoying ticking sounds from the failing purple/pinkish light that I previously used. + The green quick-release button is an awesome feature for easy rope adjustment. + It could run a little warm in a small enclosed space, but nothing out of ordinary for a 4000 light. In fact, I think it's emitting less heat than the 2000 (200w) light I got from another brand. Personally, I'm not using it with a fan, but it wouldn't hurt if you want one.
