FAQs

What coverage area does the LumaLight 400W provide?+

The LumaLight 400W is designed to provide high-intensity, uniform light coverage for a 4'x4' area, making it an ideal choice for standard-sized 4x4 grow tents during the flowering stage.

Do I need to purchase the GrowHub separately for smart control?+

Yes, the VIVOSUN GrowHub controller is sold separately. However, the LumaLight features a built-in 4-level manual dimming knob (25%, 50%, 75%, 100%), so you can adjust light intensity without the GrowHub. The controller adds advanced features like remote app control and automated scheduling.

Can I use this light throughout my entire grow cycle?+

Absolutely. The LumaLight's full-spectrum design (3000K, 5000K, 660nm red, 750nm far-red) is optimized for all growth stages—from seedling and vegetative growth to flowering and harvest. The far-red spectrum specifically helps accelerate flowering time and enhance yield quality.

How does the IP65 waterproof rating benefit my grow operation?+

The IP65 rating means the LumaLight is completely sealed against dust and protected from water jets from any direction. You can safely spray water or nutrient solutions in your grow space without worrying about damaging the light, making it perfect for high-humidity environments.

What does the 36,000-hour lifespan mean for my growing schedule?+

With a Q90 flux maintenance rate of 36,000 hours, the LumaLight maintains at least 90% of its original light output for the entire lifespan. Running 18 hours daily, that's over 5.5 years of consistent, high-intensity light. This longevity reduces replacement costs and ensures stable growing conditions season after season.

Does this light produce a lot of heat?+

No. The LumaLight features advanced thermal management technology that efficiently dissipates heat, keeping the light cool during operation. This protects internal components, extends lifespan, and reduces heat stress on your plants, minimizing the need for additional cooling equipment.

Can I daisy-chain multiple LumaLight units together?+

Yes, when using the VIVOSUN GrowHub controller, you can connect and control multiple LumaLight units simultaneously through a single app interface. This makes it easy to manage larger grow operations or multiple tents with synchronized lighting schedules.

How do I choose between different LumaLight wattage options?+

The LumaLight series offers multiple wattage options including the 100W, 150W, and 200W models. Select a model based on your grow space size and plant density. All models feature the same professional spectrum and smart control compatibility.

What's the difference between this and cheaper LED grow lights?+

The LumaLight delivers superior PPFD uniformity through strategic diode placement, ensuring every plant receives optimal light. The optimized full spectrum includes far-red LEDs for faster flowering, IP65 waterproofing for durability, and a proven 36,000-hour lifespan. For more details, check our LED grow light buying guide.
